Genosyl (nitric oxide) - Dosing, PA Forms & Info (2026)

Indications & Usage

INDICATIONS AND USAGE

GENOSYL ^®is indicated to improve oxygenation and reduce the need for extracorporeal membrane oxygenation in term and near-term (>34 weeks gestation) neonates with hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension in conjunction with ventilatory support and other appropriate agents.

Dosage & Administration

DOSAGE AND ADMINISTRATION

The recommended dose is 20 ppm, maintained for up to 14 days or until the underlying oxygen desaturation has resolved (2.1 ).

Doses greater than 20 ppm are not recommended (2.1 , 5.2 ).

Administration: Avoid abrupt discontinuation (2.2 , 5.1 ).

Dosage

Term and near-term neonates with hypoxic respiratory failure

The recommended dose of GENOSYL is 20 ppm. Maintain treatment up to 14 days or until the underlying oxygen desaturation has resolved and the neonate is ready to be weaned from GENOSYL therapy.

Doses greater than 20 ppm are not recommended [see Warnings and Precautions (5.2) ].

Administration

Nitric Oxide Delivery System

GENOSYL must be administered using a calibrated GENOSYL Delivery System. Only validated ventilator systems should be used in conjunction with GENOSYL [see Description (11) ].

Consult the GENOSYL Delivery System Operator's Manual or call 1-877-337-4118 or visit www.vero-biotech.com for needed information on training and technical support for users of GENOSYL with the GENOSYL Delivery System .

Keep available a backup power supply to address power failures. The GENOSYL Delivery System consists of a primary system and a fully functional second system that can be used as backup in the event of primary system failure.

Monitoring

Measure methemoglobin within 4-8 hours after initiation of treatment with GENOSYL and periodically throughout treatment [see Warnings and Precautions (5.2) ].

Monitor for PaO ₂and inspired NO ₂during GENOSYL administration [see Warnings and Precautions 5.3) ].

Weaning and Discontinuation

Avoid abrupt discontinuation of GENOSYL [see Warnings and Precautions (5.1) ]. To wean GENOSYL, down titrate in several steps, pausing several hours at each step to monitor for hypoxemia.

Dosage Forms & Strengths

DOSAGE FORMS AND STRENGTHS

GENOSYL (nitric oxide) is a gas available at concentrations up to 800 ppm [see Description (11) ].

Pregnancy & Lactation

USE IN SPECIFIC POPULATIONS

Pediatric Use

The safety and efficacy of nitric oxide for inhalation has been demonstrated in term and near-term neonates with hypoxic respiratory failure associated with evidence of pulmonary hypertension [see Clinical Studies (14.1) ] . Additional studies conducted in premature neonates for the prevention of bronchopulmonary dysplasia have not demonstrated substantial evidence of efficacy [see Clinical Studies (14.3) ]. No information about its effectiveness in other age populations is available.

Geriatric Use

Nitric oxide is not indicated for use in the adult population.

Contraindications

CONTRAINDICATIONS

GENOSYL is contraindicated in neonates dependent on right-to-left shunting of blood.

Warnings & Precautions

WARNINGS AND PRECAUTIONS

Rebound Pulmonary Hypertension: Abrupt discontinuation of GENOSYL may lead to worsening oxygenation and increasing pulmonary artery pressure (5.1 ).

Methemoglobinemia: Methemoglobin increases with the dose of nitric oxide; following discontinuation or reduction of nitric oxide, methemoglobin levels return to baseline over a period of hours (5.2 ).

Elevated NO ₂Levels: Monitor NO ₂levels (5.3 ).

Heart Failure: In patients with pre-existing left ventricular dysfunction, GENOSYL may increase pulmonary capillary wedge pressure leading to pulmonary edema (5.4 ).

Rebound Pulmonary Hypertension Syndrome following Abrupt Discontinuation

Wean from GENOSYL [see Dosage and Administration (2.2) ]. Abrupt discontinuation of GENOSYL may lead to worsening oxygenation and increasing pulmonary artery pressure, i.e., Rebound Pulmonary Hypertension Syndrome. Signs and symptoms of Rebound Pulmonary Hypertension Syndrome include hypoxemia, systemic hypotension, bradycardia, and decreased cardiac output. If Rebound Pulmonary Hypertension occurs, reinstate GENOSYL therapy immediately.

Hypoxemia from Methemoglobinemia

Nitric oxide combines with hemoglobin to form methemoglobin, which does not transport oxygen. Methemoglobin levels increase with the dose of GENOSYL; it can take 8 hours or more before steady-state methemoglobin levels are attained. Monitor methemoglobin and adjust the dose of GENOSYL to optimize oxygenation.

If methemoglobin levels do not resolve with decrease in dose or discontinuation of GENOSYL, additional therapy may be warranted to treat methemoglobinemia [see Overdosage (10) ] .

Airway Injury from Nitrogen Dioxide

Nitrogen dioxide (NO ₂) forms in gas mixtures containing NO and O ₂. Nitrogen dioxide may cause airway inflammation and damage to lung tissues.

If there is an unexpected change in NO ₂concentration, or if the NO ₂concentration reaches 0.5 ppm when measured in the breathing circuit, then the delivery system should be assessed in accordance with the GENOSYL Delivery System Operator's Manual troubleshooting section, and the NO ₂analyzer should be recalibrated. The dose of GENOSYL and/or FiO ₂should be adjusted as appropriate.

Worsening Heart Failure

Patients with left ventricular dysfunction treated with GENOSYL may experience pulmonary edema, increased pulmonary capillary wedge pressure, worsening of left ventricular dysfunction, systemic hypotension, bradycardia and cardiac arrest. Discontinue GENOSYL while providing symptomatic care.

Adverse Reactions

ADVERSE REACTIONS

The following adverse reactions are discussed elsewhere in the label;

Hypoxemia [see Warnings and Precautions (5.2) ]

Worsening Heart Failure [see Warnings and Precautions (5.4) ]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from the clinical studies does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.

Controlled studies have included 325 patients on nitric oxide doses of 5 to 80 ppm and 251 patients on placebo. Total mortality in the pooled trials was 11% on placebo and 9% on nitric oxide gas for inhalation, a result adequate to exclude nitric oxide mortality being more than 40% worse than placebo.

In both the NINOS and CINRGI studies, the duration of hospitalization was similar in nitric oxide gas for inhalation and placebo-treated groups.

From all controlled studies, at least 6 months of follow-up is available for 278 patients who received nitric oxide gas and 212 patients who received placebo. Among these patients, there was no evidence of an adverse effect of treatment on the need for re-hospitalization, special medical services, pulmonary disease, and neurological sequelae.

In the NINOS study, treatment groups were similar with respect to the incidence and severity of intracranial hemorrhage, Grade IV hemorrhage, periventricular leukomalacia, cerebral infarction, seizures requiring anticonvulsant therapy, pulmonary hemorrhage, or gastrointestinal hemorrhage.

In CINRGI, the only adverse reaction (>2% higher incidence on nitric oxide gas for inhalation than on placebo) was hypotension (14% vs. 11%).

Postmarketing Experience

Post marketing reports of accidental exposure to nitric oxide for inhalation in hospital staff have been associated with chest discomfort, dizziness, dry throat, dyspnea, and headache.

Drug Interactions

DRUG INTERACTIONS

Nitric oxide donor compounds may increase the risk of developing methemoglobinemia (7 ).

Nitric Oxide Donor Agents

Nitric oxide donor agents such as prilocaine, sodium nitroprusside and nitroglycerine may increase the risk of developing methemoglobinemia.

Description

DESCRIPTION

GENOSYL (nitric oxide) is administered by inhalation. Nitric oxide is a pulmonary vasodilator. Nitric oxide is generated from liquid dinitrogen tetroxide (N ₂O ₄) by the Cassette in the GENOSYL Delivery System. Upon initiation of GENOSYL Delivery System, the liquid N ₂O ₄is heated and the equilibrium shifts to nitrogen dioxide (NO ₂) gas. The NO ₂is then converted into nitric oxide (NO) using the antioxidant Cartridges, and nitric oxide is delivered to the patient by means of a ventilator or a nasal cannula. The amount of nitric oxide administered to the patient is set by controlling the temperature of the N ₂O ₄liquid module, which controls the pressure inside the liquid module, which in turn controls the mass of NO ₂that is sent to the primary Cartridges, and hence the mass of nitric oxide. The mass flow of nitric oxide, together with the air from the pump, control the nitric oxide concentration. A nitric oxide sensor monitors the nitric oxide in the patient line. GENOSYL Delivery System is designed to deliver a controlled level of nitric oxide blended with breathing air or oxygen-enriched breathing air.

The GENOSYL Delivery System controls the flow of nitric oxide mixed with air delivered to the patient.

The structural formula of nitric oxide (NO) is shown below:

Pharmacology

CLINICAL PHARMACOLOGY

Mechanism of Action

Nitric oxide relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase, activating guanylate cyclase and increasing intracellular levels of cyclic guanosine 3',5'-monophosphate, which then leads to vasodilation. When inhaled, nitric oxide selectively dilates the pulmonary vasculature, and because of efficient scavenging by hemoglobin, has minimal effect on the systemic vasculature.

GENOSYL appears to increase the partial pressure of arterial oxygen (PaO ₂) by dilating pulmonary vessels in better ventilated areas of the lung, redistributing pulmonary blood flow away from lung regions with low ventilation/perfusion (V/Q) ratios toward regions with normal ratios.

Pharmacodynamics

Effects on Pulmonary Vascular Tone in PPHN

Persistent pulmonary hypertension of the newborn (PPHN) occurs as a primary developmental defect or as a condition secondary to other diseases such as meconium aspiration syndrome (MAS), pneumonia, sepsis, hyaline membrane disease, congenital diaphragmatic hernia (CDH), and pulmonary hypoplasia. In these states, pulmonary vascular resistance (PVR) is high, which results in hypoxemia secondary to right-to-left shunting of blood through the patent ductus arteriosus and foramen ovale. In neonates with PPHN, nitric oxide gas for inhalation improves oxygenation (as indicated by significant increases in PaO ₂).

Pharmacokinetics

The pharmacokinetics of nitric oxide has been studied in adults.

Absorption and Distribution

Nitric oxide is absorbed systemically after inhalation. Most of it traverses the pulmonary capillary bed where it combines with hemoglobin that is 60% to 100% oxygen-saturated. At this level of oxygen saturation, nitric oxide combines predominantly with oxyhemoglobin to produce methemoglobin and nitrate. At low oxygen saturation, nitric oxide can combine with deoxyhemoglobin to transiently form nitrosylhemoglobin, which is converted to nitrogen oxides and methemoglobin upon exposure to oxygen. Within the pulmonary system, nitric oxide can combine with oxygen and water to produce nitrogen dioxide and nitrite, respectively, which interact with oxyhemoglobin to produce methemoglobin and nitrate. Thus, the end products of nitric oxide that enter the systemic circulation are predominantly methemoglobin and nitrate.

Metabolism

Methemoglobin disposition has been investigated as a function of time and nitric oxide exposure concentration in neonates with respiratory failure. The methemoglobin (MetHb) concentration-time profiles during the first 12 hours of exposure to 0, 5, 20, and 80 ppm nitric oxide are shown in Figure 1.

Methemoglobin concentrations increased during the first 8 hours of nitric oxide exposure. The mean methemoglobin level remained below 1% in the placebo group and in the 5 ppm and 20 ppm nitric oxide gas groups, but reached approximately 5% in the 80 ppm nitric oxide gas group. Methemoglobin levels >7% were attained only in patients receiving 80 ppm, where they comprised 35% of the group. The average time to reach peak methemoglobin was 10 ± 9 (SD) hours (median, 8 hours) in these 13 patients, but one patient did not exceed 7% until 40 hours.

Elimination

Nitrate has been identified as the predominant nitric oxide metabolite excreted in the urine, accounting for >70% of the nitric oxide dose inhaled. Nitrate is cleared from the plasma by the kidney at rates approaching the rate of glomerular filtration.

Nonclinical Toxicology

NONCLINICAL TOXICOLOGY

Carcinogenesis, Mutagenesis, Impairment of Fertility

No evidence of a carcinogenic effect was apparent, at inhalation exposures up to the recommended dose (20 ppm), in rats for 20 hr/day for up to two years. Higher exposures have not been investigated.

Nitric oxide gas has demonstrated genotoxicity in Salmonella (Ames Test), human lymphocytes, and after in vivo exposure in rats. There are no animal or human studies to evaluate nitric oxide for effects on fertility.

Clinical Studies

CLINICAL STUDIES

Treatment of Hypoxic Respiratory Failure (HRF)

The efficacy of nitric oxide gas was investigated in term and near-term newborns with hypoxic respiratory failure (HRF) resulting from a variety of etiologies. Inhalation of nitric oxide gas reduces the oxygenation index (OI= mean airway pressure in cm H ₂O × fraction of inspired oxygen concentration [FiO ₂]× 100 divided by systemic arterial concentration in mmHg [PaO ₂]) and increases PaO ₂ [see Clinical Pharmacology (12.1) ].

NINOS Study

The Neonatal Inhaled Nitric Oxide Study (NINOS) was a double-blind, randomized, placebo-controlled, multicenter trial in 235 neonates with hypoxic respiratory failure. The objective of the study was to determine whether inhaled nitric oxide would reduce the occurrence of death and/or initiation of extracorporeal membrane oxygenation (ECMO) in a prospectively defined cohort of term or near-term neonates with hypoxic respiratory failure unresponsive to conventional therapy. Hypoxic respiratory failure was caused by meconium aspiration syndrome (MAS; 49%), pneumonia/sepsis (21%), idiopathic primary pulmonary hypertension of the newborn (PPHN; 17%), or respiratory distress syndrome (RDS; 11%). Infants ≤14 days of age (mean, 1.7 days) with a mean PaO ₂of 46 mmHg and a mean oxygenation index (OI) of 43 cm H ₂O / mmHg were initially randomized to receive 100% O ₂with (n=114) or without (n=121) 20 ppm nitric oxide for up to 14 days. Response to study drug was defined as a change from baseline in PaO ₂30 minutes after starting treatment (full response = >20 mmHg, partial = 10–20 mmHg, no response = <10 mmHg). Neonates with a less than full response were evaluated for a response to 80 ppm nitric oxide or control gas. The primary results of this study are presented in Table 1.

Table 1: Summary of Clinical Results from Hypoxic Respiratory Failure Study
Control (n=121)	Nitric Oxide gas (n=114)	P value
Death or ECMO Extracorporeal membrane oxygenation ^, Death or need for ECMO was the primary end point of this study	77 (64%)	52 (46%)	0.006
Death	20 (17%)	16 (14%)	0.60
ECMO	66 (55%)	44 (39%)	0.014

Although the incidence of death by 120 days of age was similar in both groups (NO, 14%; control 17%), significantly fewer infants in the nitric oxide group required ECMO compared with controls (39% vs. 55%, p = 0.014). The combined incidence of death and/or initiation of ECMO showed a significant advantage for the nitric oxide treated group (46% vs. 64%, p = 0.006). The nitric oxide group also had significantly greater increases in PaO ₂and greater decreases in the OI and the alveolar-arterial oxygen gradient than the control group (p<0.001 for all parameters). Significantly more patients had at least a partial response to the initial administration of study drug in the nitric oxide group (66%) than the control group (26%, p<0.001). Of the 125 infants who did not respond to 20 ppm nitric oxide control, similar percentages of NO-treated (18%) and control (20%) patients had at least a partial response to 80 ppm nitric oxide gas for inhalation or control drug, suggesting a lack of additional benefit for the higher dose of nitric oxide. No infant had study drug discontinued for toxicity. Inhaled nitric oxide gas had no detectable effect on mortality. The adverse events collected in the NINOS trial occurred at similar incidence rates in both treatment groups [see Adverse Reactions (6.1) ] . Follow-up exams were performed at 18-24 months for the infants enrolled in this trial. In the infants with available follow-up, the two treatment groups were similar with respect to their mental, motor, audiologic, or neurologic evaluations.

CINRGI Study

This study was a double-blind, randomized, placebo-controlled, multi-center trial of 186 term and near-term neonates with pulmonary hypertension and hypoxic respiratory failure. The primary objective of the study was to determine whether nitric oxide gas would reduce the receipt of ECMO in these patients. Hypoxic respiratory failure was caused by MAS (35%), idiopathic PPHN (30%), pneumonia/sepsis (24%), or RDS (8%). Patients with a mean PaO ₂of 54 mmHg and a mean OI of 44 cm H ₂O / mmHg were randomly assigned to receive either 20 ppm nitric oxide gas (n=97) or nitrogen gas (placebo; n=89) in addition to their ventilatory support. Patients who exhibited a PaO ₂>60 mmHg and a pH < 7.55 were weaned to 5 ppm nitric oxide gas or placebo. The primary results from the CINRGI study are presented in Table 2.

Table 2: Summary of Clinical Results from Persistent Pulmonary Hypertension of the Newborn Study
Placebo	Nitric oxide gas	P value
ECMO Extracorporeal membrane oxygenation ^, ECMO was the primary end point of this study	51/89 (57%)	30/97 (31%)	<0.001
Death	5/89 (6%)	3/97 (3%)	0.48

Significantly fewer neonates in the nitric oxide gas group required ECMO compared to the control group (31% vs. 57%, p<0.001). While the number of deaths were similar in both groups (Nitric oxide gas, 3%; placebo, 6%), the combined incidence of death and/or receipt of ECMO was decreased in the nitric oxide gas group (33% vs. 58%, p<0.001).

In addition, the nitric oxide gas group had significantly improved oxygenation as measured by PaO ₂, OI, and alveolar-arterial gradient (p<0.001 for all parameters). Of the 97 patients treated with nitric oxide gas, 2 (2%) were withdrawn from study drug due to methemoglobin levels >4%. The frequency and number of adverse events reported were similar in the two study groups [see Adverse Reactions (6.1) ].

In clinical trials, reduction in the need for ECMO has not been demonstrated with the use of inhaled nitric oxide in neonates with congenital diaphragmatic hernia (CDH).

Ineffective in Adult Respiratory Distress Syndrome (ARDS)

In a randomized, double-blind, parallel, multicenter study, 385 patients with adult respiratory distress syndrome (ARDS) associated with pneumonia (46%), surgery (33%), multiple trauma (26%), aspiration (23%), pulmonary contusion (18%), and other causes, with PaO ₂/FiO ₂<250 mmHg despite optimal oxygenation and ventilation, received placebo (n=193) or nitric oxide gas (n=192), 5 ppm, for 4 hours to 28 days or until weaned because of improvements in oxygenation. Despite acute improvements in oxygenation, there was no effect of nitric oxide gas on the primary endpoint of days alive and off ventilator support. These results were consistent with outcome data from a smaller dose ranging study of nitric oxide (1.25 to 80 ppm). GENOSYL (nitric oxide) for inhalation is not indicated for use in ARDS.

Ineffective in Prevention of Bronchopulmonary Dysplasia (BPD)

The safety and efficacy of nitric oxide gas for the prevention of chronic lung disease [bronchopulmonary dysplasia (BPD)] in neonates ≤ 34 weeks gestational age requiring respiratory support has been studied in four large previously conducted multicenter, double-blind, placebo-controlled clinical trials in a total of 2,600 preterm infants. Of these, 1,290 received placebo, and 1,310 received inhaled nitric oxide at doses ranging from 5-20 ppm, for treatment periods of 7-24 days duration. The primary endpoint for these studies was alive and without BPD at 36 weeks postmenstrual age (PMA). The need for supplemental oxygen at 36 weeks PMA served as a surrogate endpoint for the presence of BPD. Overall, efficacy for the prevention of bronchopulmonary dysplasia in preterm infants was not established. There were no meaningful differences between treatment groups with regard to overall deaths, methemoglobin levels, or adverse events commonly observed in premature infants, including intraventricular hemorrhage, patent ductus arteriosus, pulmonary hemorrhage, and retinopathy of prematurity.

The use of GENOSYL (nitric oxide) for prevention of BPD in preterm neonates ≤34 weeks gestational age is not recommended.

Throughout this Operator's Manual, warnings, cautions, and notes will be displayed in the following manner.

WARNING
The warning box will alert the user to possible injury, death, or serious adverse reactions associated with the use or misuse of the device.

CAUTION
The caution box will alert the user about proper use of the equipment and any conditions that could result in equipment damage or failure. The user should read and adhere to all warnings and cautions.

NOTE
The note box provides information, clarification, or supplemental information to assist and educate the user on the use of the equipment.

A complete list of Warnings and Cautions for the GENOSYL DS are shown below. Where appropriate, some of these will also be shown throughout this manual.

WARNINGS
Please consult the package insert for a complete list of contraindications.
Alarms ALWAYS acknowledge and follow information provided from alarms. An alarm indicates an abnormal condition, and ignoring alarms can result in possible injury, death, or serious adverse reactions. ALWAYS use clinical judgement when setting upper or lower alarm limits. Failure to do so could result in possible injury or death.
Consoles ALWAYS have a second Console present and properly connected when a Dosing Console is connected to the patient. If the Dosing Console malfunctions, switch to the Back-up Console. If the Back-up Console is not available or properly connected, this may result in patient injury or death. DO NOT clean the GENOSYL DS with the power connected and the System turned ON, as this may lead to injury (e.g., shock). Unplug AC/DC power supply external to the System prior to cleaning. NEVER modify the equipment. Modifications of the equipment may result in malfunction, which may result in a fire, shock, injury, or death. NEVER turn the rear power switch OFF until the System has gone through a controlled shutdown or instructed by VERO Technical Support. Turning the rear power switch OFF prematurely (e.g., while it is still in use) will immediately shut down the device. This may result in interruption in NO delivery to the patient, which may cause injury or death.
Cassette DO NOT use the Cassette if the Cassette State Window is not blue. A Cassette State Window that is any color other than blue may affect the Cassette's ability to provide the correct NO dosage to the patient, which may cause injury or death. DO NOT use a Cassette that is beyond its expiration date. Using an expired Cassette may affect the Cassette's ability to provide the correct NO dosage to the patient, which may cause injury or death. MAKE SURE the System stabilizes to the prescribed concentration (ppm) of NO prior to leaving the Console unattended. Failure to do so could result in under delivery of the target NO, leading to injury or harm. ALWAYS replace a Cassette once depleted. A depleted Cassette will interrupt patient dosing and can lead to underdosing and/or injury to the patient. ALWAYS follow Cassette inspection instructions prior to Cassette insertion. Not inspecting the Cassette prior to insertion may lead to using a faulty Cassette, resulting in injury.
Use in the MR Environment The GENOSYL DS is classified as MR Conditional with MR scanners of 1.5 or 3.0 Tesla strength ONLY in areas where the field strength is less than 100 gauss. ALWAYS operate at a fringe field of less than 100 gauss. This device contains ferromagnetic components and may experience strong attraction close to the magnet. DO NOT exceed 100 gauss; System operation may be impacted. Confirm Cart caster lock function. Optionally connect tether. NEVER use the GENOSYL DS in the MR scanner room without gauss alarms installed. ALWAYS verify at least one gauss alarm is functioning properly prior to use in the MR environment. DO NOT use the GENOSYL DS in the MR environment if neither gauss alarm is functional. ALWAYS move System away from the MR scanner if the gauss alarm sounds. The gauss alarm will sound if the System is too close to the MR scanner. Move System away from the MR scanner until the gauss alarm stops sounding. ALWAYS verify that the GENOSYL DS Cart casters are locked after positioning the System in the MR scanner room. ALWAYS verify that the GENOSYL DS is securely attached to the Cart. ALWAYS arrange power cord, MR patient gas sample line, and NO delivery line to avoid entanglement, strangulation and/or a trip hazard. DO NOT use the GENOSYL DS in the MR environment if the Cart moves when the brake caster locks are engaged. NEVER perform NO or NO ₂calibration within the MR scanner room. Calibration equipment is a potential projectile hazard.
Transport ALWAYS ensure the GENOSYL DS Dosing and Back-up Consoles are securely affixed to the External Transport Mounts when the System will be used in a transport vehicle. ALWAYS ensure Consoles are placed into External Transport Mode before inserting a Cassette for external transport outside of the hospital. ONLY use External Transport Cassettes, identified by orange color and transport sticker, in external transport outside of the hospital. ALWAYS ensure the External Transport Mounts are secured during patient transport, per hospital protocols.
Use with Anesthesia Gas Machines ALWAYS use the Anesthesia Gas Machine (AGM) in accordance with the manufacturer's instructions. The flow out of the anesthesia gas machine via the INSPIRATORY breathing circuit limb must pass through the GENOSYL DS Gas Injection Assembly. The GENOSYL DS injects and samples gas from the patient respiratory circuit which may affect the triggering sensitivity of the anesthesia gas machine (AGM). ALWAYS ensure the trigger sensitivity of the AGM is checked after connecting the GENOSYL DS to the breathing circuit and starting iNO delivery or when the dose is changed and adjust trigger sensitivity as necessary. Failure to do so may lead to AGM auto cycling or apnea alarm. ALWAYS ensure the patient disconnect and high–pressure alarms are used with the AGM. Ensure the Injection Assembly and the Gas Sample Tee are BOTH inserted on the inspiratory limb of the circuit.
Connections ALWAYS follow pre-use setup instructions for the routing and connections of tubing to avoid patient strangulation. MAKE SURE the System has all tubing connected as described in the instructions. Not connecting all tubing may result in inaccurate dosage and harm the patient. NEVER touch the electrical connectors of the System or its accessories, and the patient simultaneously. If the user touches another device with a ground-fault failure and simultaneously touches the GENOSYL DS, this can result in injury (e.g., shock) should a grounding failure be present.
Battery ONLY properly trained personnel should replace the battery. Incorrectly replacing the battery may result in a hazard such as excessive temperatures, fire, or explosion. MAKE SURE the GENOSYL DS is connected to AC wall power to charge the battery a minimum of once every 3 months to maintain a minimum battery charge. Failure to recharge the Console battery for extended timeframes may result in full discharge of the battery. If a Battery Error message occurs during startup of the System, contact Technical Support at 877-337-4118 for assistance.
User ONLY intended users who are experienced in the use of this System should use this device. US federal law restricts device use to licensed medical professionals. If device is used by unintended users, device can be misused and lead to injury or death.
Alternative Means of Ventilation ALWAYS ensure that the manual flow displayed on the Console matches the flow set into the resuscitation bag. Incorrect flow settings may result in an incorrect estimation of NO delivery. If the flow into the manual equipment is too low, there is risk of overdosing the patient with NO. ALWAYS squeeze the bag several times, after starting fresh gas flow, to empty residual gas in the bag prior to using the System to ventilate a patient. Failure to do so could result in higher NO ₂levels being delivered to the patient. ALWAYS use the smallest bag adequate to deliver the desired tidal volume. Failure to do so could result in higher NO ₂levels being delivered to the patient.
Patient Monitoring ALWAYS constantly monitor the patient. System malfunctions can occur if device and patient are not monitored and can result in injury or death. Careful monitoring is required by care personnel whenever the System is used on a patient. The use of an alarm and a monitoring system does not give an absolute assurance of warning for every malfunction that may occur. Certain alarms may require immediate response.
Use with Breathing Devices ONLY use a manual resuscitation bag with the GENOSYL DS for a short time (e.g., less than one hour) when on battery only. Otherwise, the System may shut off and may result in injury or death. The GENOSYL DS injects and samples gas from the patient respiratory circuit which may affect the triggering sensitivity of the ventilator. ALWAYS ensure the trigger sensitivity of the ventilator is checked after connecting the GENOSYL DS to the breathing circuit or when the dose is changed and adjust trigger sensitivity as necessary. Failure to do so may lead to ventilator auto cycling or apnea alarm. ALWAYS ensure the patient disconnect and high-pressure alarms are used with the ventilator. ONLY use the GENOSYL DS with Bio-Med Crossvent 2+ with Constant Flow ON. Not doing so may lead to elevated NO2 levels or dose variability.
Set-up ONLY VERO Biotech authorized equipment technicians are to perform the initial System set-up prior to initial use. Failure to use an authorized equipment technician can result in a patient or user injury. ONLY store the GENOSYL DS as outlined in the storage instructions. Not storing the device in alignment with its storage instructions can cause the device to be unsafe and lead to injury or death. AVOID using the GENOSYL DS adjacent to or stacked with other equipment, as it may result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally. DO NOT use accessories or cables other than those specified or provided by the manufacturer of this equipment, as this may result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation. DO NOT place portable RF communications equipment (including peripherals such as antenna cables and external antennas) closer than 30cm (12 inches) to any part of the GENOSYL DS, including cables specified. Otherwise, degradation of the performance of this equipment could occur, resulting in injury. Only connect to a power outlet with protective earth. Failure to connect to an outlet with protective earth may result in an electrical shock.
Troubleshooting ALWAYS ensure patient safety before troubleshooting (such as an activated alarm) or replacing a problematic item. Not monitoring the patient prior to attending to an alarm can result in injury or death.
Calibration ONLY use the calibration gas pressure regulators supplied by the manufacturer. Pressure regulators not supplied by the manufacturer may damage the sensors and may lead to patient injury. ALWAYS verify the correct NIST traceable calibration gas is being used and confirm the expiration date of the calibration gas prior to performing calibration. The use of incorrect or expired gas may result in inaccurate sensor readings and can lead to patient injury.
Cleaning and Maintenance NEVER submerge the GENOSYL DS, Cassettes, or non-disposable Adaptive Sensor Cable. Submerging in liquids will damage the System and could cause electrical shorts which may result in injury or death.
Water Trap ALWAYS empty Water Trap when prompted by the System, and when the trap is more than half full. Allowing the Water Trap to completely fill will occlude the Sample Line which will interrupt patient gas NO, NO ₂, and O ₂concentration monitoring. Failure to monitor the patient gas NO, NO ₂, and O ₂concentrations may result in patient injury. ALWAYS conduct Water Trap / Sample Line Leak Test every time you empty and replace the Water Trap, as failure to do so may lead to an incorrect NO reading, which can result in injury or death. ALWAYS use a Water Trap supplied by the manufacturer. Using an incorrect Water Trap could result in non-functioning or inaccurate sensor readings.
Use Outside of Product Labeling ALWAYS use the GENOSYL DS in accordance with the indications, usage, contraindications, warnings, and precautions described in the GENOSYL prescribing information and labeling. Refer to latest approved prescribing information and labeling prior to use. The approved patient population for the GENOSYL DS as specified in the drug labeling for GENOSYL (nitric oxide) for inhalation, is limited to neonates. The GENOSYL DS is not intended to be used in other patient populations. ONLY use the GENOSYL DS, its parts, and accessories as instructed. Using non-specified components may result in product malfunction, injury, or death ONLY trained personnel should operate the GENOSYL DS. Failure to do so can result in injury or death. ONLY mechanical ventilators validated with the GENOSYL DS should be used. Not using a validated ventilator system can result in injury or harm.

CAUTIONS
Supplied Instructions ALWAYS refer to the instructions supplied with all equipment to be used in conjunction with the GENOSYL DS for their intended uses, contraindications, and potential complications. Misuse of the device or its components may damage the device.
Cassette DO NOT remove Cassette from packaging until ready to use. External packaging is designed to protect the Cassette from damage and/or contamination. User should always have a secondary Cassette inserted in the Dosing Console and preheated in order for auto transition to occur. User should replace depleted Cassette as soon as possible after ejection.
Consoles ALWAYS operate the Console on a level surface to avoid potential interruption to nitric oxide (NO) delivery. ONLY use recommended cleaning agents or a damp cloth to clean the Console and limit use of liquids around Console. Excess water can permanently damage the device. ONLY use the GENOSYL DS with the power cord supplied by the manufacturer. Use of a generic power cord may cause output voltage instability leading to a touch screen failure. ALWAYS ensure the power cord is firmly seated into the power supply and the wall outlet. A loose connection can result in damage to the device or faulty operation. Prolonged use in dry environments without humidification will damage the gas sensors. Supplemental humidification providing greater than 20% relative humidity (RH) in the patient circuit is recommended.
Use with Breathing Devices When using spontaneous breathing modes on respiratory device, NO ₂levels may exceed 3.0 ppm NO when dosing ≥ 57 ppm NO into 100% FiO ₂and maximum bias flow, resulting in nitric oxide delivery interruption. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose. Refer to Section 12.1.5 Table 13 for additional information. When using non-spontaneous breathing modes on respiratory device NO ₂levels may exceed 3.0 ppm when dosing ≥ 63 ppm NO into 100% FiO ₂and maximum bias flow, resulting in nitric oxide delivery interruption. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose. Refer to Section 12.1.5 Table 13 for additional information.
Use with Anesthesia Gas Machines The Adaptive Sensor is recommended for use with anesthesia gas machines (AGMs). When using an AGM without the Adaptive Sensor, transient dose excursions outside of the set NO dose may occur during Cassette transition, and changes in breathing circuit flow may cause fluctuations in measured levels of NO and NO ₂when using the manual ventilation bag integrated with the AGM. When using anesthesia gas machines, NO ₂levels may exceed 3.0 ppm when dosing ≥ 58 ppm NO into 100% FiO ₂, resulting in nitric oxide delivery interruption. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose. DO NOT use in environments with <20% relative humidity (RH) in the absence of supplemental humidification. Prolonged use in dry environments without humidification will damage the gas sensors. GENOSYL DS was validated with listed AGMs using a Heat Moisture Exchanger (HME) and was not tested with heated humidification connected to the respiratory circuit. Rebreathing validation testing was performed with semi-closed breathing systems. Non-rebreathing validation testing was perfumed with semi-open breathing systems. The GENOSYL DS has not been evaluated with fully open or fully closed anesthesia breathing systems.
Gas Sampling During Aerosol Delivery Pneumatic Nebulizers will dilute the delivered nitric oxide dose.
Calibration ALWAYS perform a full-scale calibration of the GENOSYL DS when prompted by the System prior to use. ALWAYS confirm the correct flow direction of the installed one-way check valve in the sampling tee to avoid over pressurization of the sample system and damage to the device.
Cleaning and Maintenance ALWAYS follow maintenance instructions in this manual for your safety and to prevent damage to the System. ALWAYS power down the GENOSYL DS Console when not in use. DO NOT sterilize (e.g., autoclave, gas sterilize) any of the components of the System, as this may compromise performance. DO NOT use harsh cleaning agents. Doing so may impair the structural integrity and/or function of the device. DO NOT touch or rub the display screen with abrasive cleaning compounds, as they may scratch and damage the screens. ALWAYS ensure the System is completely dry after cleaning before powering it ON. Failure to do so could result in equipment damage.
Switching OFF the System NEVER turn the rear power switch OFF until the System has gone through a controlled shutdown or instructed by VERO Technical Support. Turning the rear power switch OFF prematurely (e.g., while it is still in use) will immediately shut down the device and may cause improper operation upon restart.
Cart DO NOT stand or sit on the Cart. Standing or sitting on the Cart can damage the device. ALWAYS push or pull the Cart using the handle only. NOT doing so may result in damage to the device.

GENOSYL ^®DS

SECTION 1
GENERAL INFORMATION

1. GENERAL INFORMATION

1.1 User Responsibility

The GENOSYL DS (Console) will perform as described in this Operator's Manual, accompanying inserts, and/or labels when assembled, operated, maintained, and repaired in accordance with the instructions provided. The Console must be set up as described in Section 3 . If the Console does not perform as described in Section 3 or during assembly, the parts are found to be broken, missing, contaminated, or visibly worn, they should be replaced immediately.

In the case of repair or replacement of the Console is required, a telephone service request should be made to Technical Support at 877-337-4118. The GENOSYL DS or any of its parts should not be serviced or repaired by anyone other than a VERO Biotech Technical Engineer or without written permission from VERO Biotech Technical Engineering Department.

Any malfunction resulting from faulty maintenance, improper repair, damage, alteration by anyone other than a VERO Biotech Technical Engineer, and/or improper use will be the sole responsibility of the User.

WARNING
The GENOSYL DS must only be used in accordance with the approved indications, usage, contraindications, precautions, and warnings described in the GENOSYL DS labeling. Refer to the labeling prior to use.

CAUTION
U.S. Federal law restricts this device to sale by or on the order of a physician. Outside the U.S., check local laws for any restrictions that may apply.

NOTES
Prior to using the GENOSYL DS, read through this Operator's Manual. Follow all instructions and obey the Warnings and Cautions. Keep this Operator's Manual available to readily answer questions. Read through all manufacturer Operator's Manuals for the ventilator, humidifier and any other accessory items used.

1.2 General Information and Indications for Use

GENOSYL DS generates and delivers NO for inhalation at the point of use. The concentration of NO, as set by the user, is monitored, and adjusted to accurately dose the patient throughout an inspired breath. Only validated devices / components should be used with the GENOSYL DS.

The intended population for inhaled NO treatment is term and near-term neonates in neonatal intensive care units (NICUs). Refer to the GENOSYL (nitric oxide) for inhalation drug label for more detailed information.

The GENOSYL DS is intended for use in the hospital, 1.5 Tesla and 3.0 Tesla diagnostic imaging environments, during patient transfer via rescue vehicle, fixed wing aircraft, or helicopter, and the operating room in conjunction with validated anesthesia gas machines.

The GENOSYL DS is intended for use by healthcare professionals (HCPs) who are licensed and actively practicing pediatric and/or neonatal respiratory therapists (RTs), or HCPs in the operating room with the supervision of RTs in the United States. These users are required to set up, administer inhaled nitric oxide (iNO) and provide respiratory care (including initiation and maintenance of mechanical ventilators) in the critically ill neonatal population.

The GENOSYL DS starts with liquid N ₂O ₄/NO ₂, which is then converted in a proprietary Cassette to NO. The GENOSYL DS delivers NO into the ventilator stream, where the NO joins a stream of air or O ₂and is diluted to the prescribed concentration.

The NO concentration (dose) to be delivered to the patient is selected by the user and is set and maintained independently by means of computer-controlled air pumps, Cassette heaters, and a feedback loop that measures the delivered NO concentration.

The GENOSYL DS takes a gas sample removed from the NO gas flow stream immediately prior to the patient and provides real-time output of the NO, NO ₂, and O ₂concentrations that are being delivered to the patient. The continuous integrated gas monitoring includes a comprehensive alarm system.

The NO concentration detected from the sample line is used in a feedback loop to adjust the NO concentration delivered into the ventilator circuit.

The GENOSYL DS includes a redundant Console for complete back-up capability for delivery of NO for inhalation. Each Console has a back-up battery that is expected to last up to four hours under optimal conditions in the absence of an external power source. Console will alarm when less than 15 minutes of battery life remains.

1.3 Principles of Operation

GENOSYL DS . The GENOSYL DS continuously introduces a precisely controlled concentration of nitric oxide (NO) into the inspiratory limb of the ventilator circuit. GENOSYL DS utilizes the known properties of NO and other oxides of nitrogen, namely dinitrogen tetroxide (N ₂O ₄) and nitrogen dioxide (NO ₂), to create a "tankless" drug/device combination System to produce, at the point of use, ultra-high purity NO for inhalation, providing a consistent, prescribed dose to the patient.

Console. The GENOSYL DS Console contains the electronics to control the production and to maintain the constant and precise delivery of NO.

The primary features of the Console front panel are displayed in Figure 1.

NO generation. The Console uses Cassettes containing liquid N ₂O ₄/NO ₂inside a stainless-steel vessel (the liquid module) and an antioxidant cartridge. Upon initiation of a Cassette, the liquid N ₂O ₄is heated, producing NO ₂gas, which is mixed with up to 0.9 LPM ambient air supplied by the Console. The NO ₂/air is injected into the antioxidant cartridge inside the Cassette, which converts NO ₂to NO.

The Cassette is designed to provide NO in concentrations up to 80 ppm. The maximum and minimum delivered dose for a range of constant inspiratory flow rates is presented in Figure 2.

The maximum combination of dose (ppm) and flow (LPM) output of the System is 800 ppm × LPM (e.g., 20 ppm with 40 LPM, 40 ppm at 20 LPM, etc.). The System is capable of delivering NO at a minimum of 1 ppm × LPM (e.g., 1 ppm at 1 LPM).

The total time to deplete the Cassette N ₂O ₄contents depends on the rate of use. The minimum time to depletion based on use rate for Hospital Cassettes is shown in Figure 3. The minimum time to depletion of the External Transport Cassette based on use rate is shown in Figure 4. The calculated minimum remaining contents at the current output rate is indicated by a gauge presented on the Console display during use.

NO Injection into the Ventilator Circuit . After NO is produced in the Cassette, the NO injector introduces the concentrated NO into the ventilator circuit where the NO is diluted to the prescribed concentration (dose) and mixed with the O ₂or air supplied to the patient.

GENOSYL Smart Feedback System ^™Before the gas mixture reaches the patient, a sample line removes a small gas sample and sends it back to the Console, where gas sensors continuously measure the supplied NO, NO ₂and O2. The Console software then compares the measured NO concentration to the set NO concentration and continuously adjusts the delivery of NO to maintain the prescribed NO concentration (dose) delivered to the patient (closed loop control). The Console software commands the NO injection flow rate into the ventilator circuit with a maximum flow rate of 0.9 LPM. Changes in the ventilator settings by the user may cause brief transient changes in the measured NO value. The Console software will adjust the injected flow rate and the internal temperature of the Cassette to compensate for the changes in the total ventilator flow rate. For example, a higher minute ventilation will require a higher injection flow rate to produce the same NO concentration.

Mixer . An inline Mixer is used in the applicable ventilator circuit after the NO injection site and before the gas sample site to mix NO from the Console with the gas supplied by the ventilator, for specific ventilator and tidal volume use cases per Section 12.2.

Gas Monitoring. The gas mixture delivered to the patient by the GENOSYL DS is continuously monitored with two NO detectors, with one providing redundant back-up, as well as a detector for NO ₂and O ₂. A sample of inspired gas is taken from the inspiratory limb, close to the patient, and is measured by the gas sensor within the Console. The gas monitoring sensors are electrochemical; they are specific to each gas and provide an electronic signal that is proportional to the concentration of gas present.

Adaptive Sensor. The Adaptive Sensor is used to detect flow in the patient breathing circuit. When flow is not detected by the Adaptive Sensor, nitric oxide delivery will be interrupted until flow is detected. The Console will provide a visual and audible low priority alarm when flow is not detected to alert the user (see Section 10.5 ). Once flow is detected, the Console will auto resume delivery of nitric oxide at the previously set dose. An Adaptive Sensor is recommended for use with certain breathing devices. Refer to Section 3 for recommended set up diagrams. The GENOSYL DS will properly deliver and control nitric oxide dose in the absence of an Adaptive Sensor.

Alarms and Dosing Safeguard Fallback Modes. The GENOSYL DS alerts the user in the event of excursions of NO, NO ₂, and Oxygen from their expected ranges. Nitric oxide delivery interruption conditions are as follows:

NO > 100 ppm
NO ₂reaches 3 ppm
The measured respiratory circuit dilution flow drops below 0.3 LPM as measured by the Adaptive Sensor.

The Console will provide a visual and audible high priority alarm. When detecting a sustained gas level higher than the above limits for 11 consecutive seconds, the Console will interrupt delivery of NO until the sampled levels of NO and/or NO ₂decrease to a safe level. Once sampled levels are in acceptable range, the Console will resume delivery with previously set dose.

If the cause of the high gas cannot be resolved, the use of the Back-up Console may be required. Refer to Section 10.1 for additional information on alarms and dosing safeguards.

If NO delivery was interrupted due to the GENOSYL DS Adaptive Sensor reading dropping below 0.3 LPM, the Console will resume delivery with the previously set dose once the Adaptive Sensor reading exceeds 0.35 LPM. The automatic resumption of dose delivery after the interruption conditions listed above are cleared is one of the safety fallback modes of the GENOSYL DS.

Back-up NO Delivery. The Back-up Console is used to administer nitric oxide when the Dosing Console cannot be used. This Console has a separate power supply, and at least one Cassette loaded and preheated. If the Dosing Console fails to deliver NO, the Back-up Console is ready to begin dosing to continue NO delivery.

Transition to a new Cassette. When a Cassette approaches depletion, the Dosing Console will automatically transition to the second Cassette in the Console. Once the dosing Cassette is depleted, the Dosing Console will eject the depleted Cassette and alert the user to replace via the Cassette Status Indicator.

Disposal of the Cassette . Following use, any remaining Cassette contents are purged into an inerting chamber, where the contents are chemically neutralized, rendering the Cassette safe for disposal.

1.4 Exposure of Healthcare Providers to NO and NO ₂

Occupational exposure of healthcare providers to NO or NO ₂may occur during Inhaled NO therapy for patients. Below are examples of calculated and observed exposure to NO or NO ₂, in the context of guideline workplace exposure limits.

Calculated and observational methods show that the exposure levels to NO or NO ₂from an NO delivery system are significantly less than the levels recommended by the National Institute for Occupational Safety and Health (NIOSH).

Workplace Limits : NIOSH has recommended workplace exposure limits as follows NIOSH Pocket Guide to Chemical Hazards, Dept of Health & Human Services, Centers for Disease Control and Prevention, National Inst for Occupational Safety & Health. Publication 2005-149, Sept 2007. .

NO	time-weighted (8 hours) average concentration limit of 25 ppm
NO ₂	Recommended exposure limit of 1 ppm

Theoretical Calculation. The build-up of NO in a well-ventilated ICU room, with NO flowing directly into the room, can be evaluated using the following calculation:

Room size	1000 ft ³
Room volume	28,300 L
Room ventilation (6 complete exchanges/hour)	2,830 L/min
NO flow into the room	80 ppm at 14 L/min
Average NO room concentration	0.4 ppm of NO

Observations of NO Exposure . The theoretical calculation has been supplemented by actual measurements in three independent studies in actual therapeutic use settings. Hess et al, Use of Inhaled Nitric Oxide in patients with Acute Respiratory Distress Syndrome. Respiratory Care 1996; 41(5):424-446. ^, Phillips M, Hall TA, Sekar K, Tomey JL. Assessment of Medical Personnel Exposure to Nitrogen Oxides During Inhaled Nitric Oxide Treatment of neonatal and Pediatric Patients. Pediatrics. 1999;104(5):1095-1110. ^, Qureshi MA, Shah NJ, Hemmen CW, Thill MC, Kruse JA.Exposure of Intensive Care Nurses to Nitric Oxide and Nitrogen Dioxide during Therapeutic use of Inhaled Nitric Oxide in Adults with Acute Respiratory Distress Syndrome. Am. J. Crit Care, 2003;12(2):147-153. The studies found that detectable exposures to NO and NO ₂were brief, infrequent, and well below recommended exposure limits.

If the location for using NO has uncertain ventilation, then the location should be evaluated for NO and NO ₂build-up prior to use.

CASSETTE STATUS INDICATOR DISPLAY	DESCRIPTION
	This Cassette Status Indicator will be displayed when a Cassette is not loaded into the Console. The Cassette Status Indicator will display "REPLACE" and will alternate between a dark red and light red. The user is prompted to "Replace"
	This Cassette Status Indicator is displayed during the warmup phase when a new Cassette is inserted. This indicator will display "WARMING" alternating with "READY". Dose may be initiated while the Cassette is warming.
	This Cassette Status Indicator is displayed once the Cassette has achieved a fully preheated status.
	This Cassette Status Indicator is displayed during dosing. If a secondary Cassette has been inserted, the Cassette Status Indicator will display "Dosing" for the dosing Cassette and "Ready" for the secondary Cassette. If a secondary Cassette has not been inserted, the Cassette Status Indicator will display the percentage of nitric oxide remaining in the dosing Cassette and the secondary Cassette Status Indicator will be red and display "Replace". A low priority tone will also sound in ten second intervals until a secondary Cassette is inserted.
	This Cassette Status Indicator will be displayed when the Console is transitioning from the dosing Cassette to the secondary Cassette. The direction of the arrow indicates the Cassette that is being transitioned to.
	This Cassette Status Indicator will be displayed when less than one hour of Cassette life remains and no secondary Cassette is inserted. The indicator will display the percentage of life remaining in the dosing Cassette and the estimated time before depletion. The Cassette Status Indicator for the dosing Cassette will appear yellow and display "Dosing" and the other Cassette Status Indicator will appear red and display "Replace"
	This Cassette Status Indicator is displayed when a Cassette is depleted and no secondary Cassette is inserted in the Console. This status will only display if another Cassette is not present in the Console. The Cassette Status Indicator for the dosing Cassette will appear red and display "Dosing 0%" and "0m". The empty Cassette Status Indicator will appear red and display "Replace". Both indicators will alternate between a dark and light red color.
	This Cassette Status Indicator will be displayed when a Cassette that has previously been used is inserted in a Console. The Cassette display will alternate between "USED" and an "X" through the Cassette icon. The Console will automatically eject a previously used Cassette.
	This Cassette Status Indicator will be displayed two minutes after inserting one Cassette into the Back-up Console. The secondary Cassette Status Indicator on the screen will switch from a red flashing "REPLACE" to an empty gray Cassette outline. Once a dose is entered, and the inserted Cassette is activated, the outline will switch back to the red flashing "REPLACE" so the user is prompted to insert a secondary Cassette in the dosing Console.
	This Cassette Status Indicator is displayed when a Cassette is non-operational. A white X will appear over a red Cassette Status Indicator. The Console will eject a non-operational Cassette and dose from the secondary Cassette, if properly inserted. User will be prompted to replace Cassette after ejection.
	This Cassette Status Indicator is displayed when a Cassette is past its expiration date. The display will read "EXPIRED". An expired Cassette cannot be used for dosing and will be automatically ejected from the Console. User will then be prompted to replace the ejected Cassette via the Cassette Status Indicator.
	This Cassette Status Indicator will be displayed when the wrong Cassette type is inserted into the Console. The display will read "WRONG TYPE" then proceed to eject the incorrect Cassette from the Console. A Hospital Cassette will be ejected while External Transport Mode is turned ON and an External Transport Cassette will be ejected while External Transport Mode is turned OFF.

2.11 Display Screen - Adaptive Sensor Status

The following describes the Adaptive Sensor status that will be shown on the display screen. The Adaptive Sensor Icon is located on the top left of the Console display screen. To troubleshoot the Adaptive Sensor, see Section 10.8 Troubleshooting .

ADAPTIVE SENSOR DISPLAY	DESCRIPTION
	The Console has detected flow through the Adaptive Sensor.
	The Console has detected an Adaptive Sensor without flow. To initiate delivery, the Console requires flow detection. The Set button will not appear until flow is detected through the Adaptive Sensor. The screen will appear as pictured below. Once flow is detected, the "Set" button will appear and allow the user to set the dose. If the Adaptive Sensor stops detecting flow while dosing, the Console will interrupt delivery of NO into the circuit and display a turquoise "Flow Not Detected-Nitric Oxide Delivery Interrupted" message. This message will be accompanied by a low tone every 10 seconds. See Section 10.5 Low Priority Alarms and Messages .
	The Console does not detect an Adaptive Sensor is connected
	An Adaptive Sensor is detected but the Adaptive Sensor is either malfunctioning or not properly connected to the Adaptive Sensor Cable.

2.12 Cassette Insertion into Console

WARNING
ONLY use External Transport Cassettes, identified by orange color and transport sticker, in external transport outside of the hospital.

When inserting a Cassette into a Console, it is important to push the Cassette fully into the receptacle and confirm the Cassette has been registered on the screen.

PHOTO	DESCRIPTION
	Insert the Cassette into the receptacle. Push in until you hear the Cassette click into the mechanism.
	The on-screen Cassette Status Indicator will switch to say "READY" and then prompt the user to begin a Water Trap/ Sample Line Leak Test.

2.13 Water Trap / Sample Line Leak Test

A Water Trap / Sample Line Leak Test is initiated when a Cassette has been inserted into the Console and fully seated, and if the measured NO is less than 1.0 ppm. Its purpose is to test the integrity of the Water Trap seal, the proper seating of the Water Trap, and the Sample Line connection to each Console, prior to operation. This is important to ensure an accurate measurement of NO within the ventilator circuit.

After the test has been initiated, the screen will prompt the Operator to close the Stopcock Valve and the Operator will have 60 seconds within which to do this . A numerical timer and a horizontal progress bar provide a visual representation of the time elapsed (red) and time remaining (gray). Once the Stopcock Valve has been closed and if the test has been successfully completed, the entire progress bar will turn green.

TEST IN PROCESS	TEST PASSED

Figure 16: Water Trap / Sample Line Leak Test

If the test has failed, the progress bar will remain red throughout the full 60 seconds. The Operator will be notified and prompted to troubleshoot the potential cause

Prior to completion of the leak test and if a condition exists in which immediate NO delivery is required, the Operator may cancel the leak test. The GENOSYL DS will allow a dose of 20 ppm to be set in Primary Dosing Mode. If a different dose is required, a Water Trap /Sample Line Leak Test must be completed.

The Water Trap / Sample Line Leak Test may also be initiated manually via the "Settings" tab and pressing the "Perform Leak Test" button. This may be useful to test the integrity of the Water Trap and Sample Line independent of the need to initiate the delivery of nitric oxide (see Settings in Section 2.8 ).

2.14 Console Shutdown - Cassette Status Indicator

The following describes the Cassette Status Indicators that will be shown on the display screen as the Console is shutting down. For proper Console shutdown procedures, see Section 6 .

USE WITH ANESTHESIA GAS MACHINE

9. USE WITH ANESTHESIA GAS MACHINES

WARNING

ALWAYS use the GENOSYL DS in accordance with the indications, usage, contraindications, warnings, and precautions described in the GENOSYL prescribing information and labeling. Refer to latest approved prescribing information and labeling prior to use.
ALWAYS use the Anesthesia Gas Machine (AGM) in accordance with the manufacturer's instructions.
The approved patient population for the GENOSYL DS as specified in the drug labeling for GENOSYL (nitric oxide for inhalation (iNO)) is limited to neonates. The GENOSYL DS is not intended to be used in other patient populations.

CAUTION
Rebreathing validation testing was performed with semi-closed breathing systems. Non-rebreathing validation testing was performed with semi-open breathing systems. The GENOSYL DS has not been evaluated with fully open or fully closed anesthesia breathing systems.

NOTE

The GENOSYL DS performs as specified in this Operator's Manual independent of anesthetic agent, anesthetic agent concentration, and fresh gas flow rate.
Changes in the AGM ventilator settings, fresh gas flow rate, or pushing the Oxygen Flush button by the user may cause brief transient changes in the measured NO value.
Use of an Adaptive Sensor is recommended for use with AGMs. If not using an Adaptive Sensor:
- And using rebreathing fresh gas flow rates, it is recommended that the < 2.5 LPM Total Flow setting be selected.
- And using non-rebreathing fresh gas flow rates, it is recommended that the Total Flow selection based on the minute volume be selected

Compatibility testing has demonstrated performance meeting requirements for the GENOSYL DS operating range of 0 to 80 ppm with the following anesthesia gas machines at the operating ranges shown in Table 5 for both mechanical and manual AGM ventilation modes. Fresh gas flow rates between 0.5 LPM and 15 LPM (10 LPM maximum tested when rebreathing), and I:E ratios ranging from 1:2 to 1:4 were validated. At low breath rates and high tidal volume settings, NO doses above 60 ppm could result in elevated NO2 levels.

See Section 12.2 Table 14 for modes validated for each anesthesia gas machine.

The Adaptive Sensor is recommended for use with anesthesia gas machines (AGMs). When using an AGM without the Adaptive Sensor, transient dose excursions outside of the set NO dose may occur during Cassette transition, and changes in breathing circuit flow may cause fluctuations in measured levels of NO and NO ₂when using the manual ventilation bag integrated with the AGM.
When using anesthesia gas machines, NO ₂levels may exceed 3.0 ppm when dosing ≥ 58 ppm NO into 100% FiO ₂, resulting in nitric oxide delivery interruption. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose.

Table 5: Anesthesia Gas Machine Validation Compatibility Test Ranges Inspiratory Flow Rate is not measured by Anesthesia Gas Machines.

Peak Inspiratory Pressure If testing range is higher than the max setting of the Anesthesia Gas Machine, the highest setting available was tested.	0-70	cmH ₂O
Positive End Expiratory Pressure	0-20	cmH ₂O

Specific use cases may require the use of an Inline Mixer which is used to mix the NO gas with the gas supplied by the AGM through a filter containing silica gel to provide intra-breath NO delivery for certain scenarios. Refer to Table 6 below for use case scenarios.

9.1 Connection to a Dual Limb Anesthesia Circuit

The validated anesthesia circuit configurations are indicated in Table 6 above and an illustrated circuit diagram is presented in Figures 30 and 31 . For additional instructions on System set-up, refer to Section 3.5 GENOSYL DS Gas Line Connections, Section 4 System Start up, and Section 5 Nitric Oxide Administration.

NOTE
Connections to various AGMS are unique to each manufacturer as well as their corresponding disposable circuits.

CAUTION
DO NOT use in environments with <20% relative humidity (RH) in the absence of supplemental humidification. Prolonged use in dry environments without humidification will damage the gas sensors. GENOSYL DS was validated with listed AGMs using a Heat Moisture Exchanger (HME) and was not tested with heated humidification connected to the respiratory circuit.

9.2 Connection Instructions for the GENOSYL DS to an Anesthesia Gas Machine

WARNING

The flow out of the anesthesia gas machine via the INSPIRATORY breathing circuit limb must pass through the GENOSYL DS Gas Injection Assembly.
The GENOSYL DS injects and samples gas from the patient respiratory circuit which may affect the triggering sensitivity of the anesthesia gas machine (AGM). ALWAYS ensure the trigger sensitivity of the AGM is checked after connecting the GENOSYL DS to the breathing circuit and starting iNO delivery or when the dose is changed and adjust trigger sensitivity as necessary. Failure to do so may lead to AGM auto cycling or apnea alarm.
ALWAYS ensure the patient disconnect and high–pressure alarms are used with the AGM.

NOTE

A dual limb anesthesia breathing circuit should be used for iNO delivery with the GENOSYL DS.
The GENOSYL DS Sample Line must be placed on the INSPIRATORY limb of the breathing circuit between 6 and 12 inches from the patient wye. If the sampling line is placed greater than 6 inches from the patient wye it minimizes the sampling of mixed inspired/expired gas concentrations and if placed less than 12 inches from the patient wye it ensures correct iNO and NO ₂measurement.

DISPLAY	ACTION	Warnings, Cautions and Notes
	Connect the Inline Breathing Circuit Filter to the Gas Injection Adapter (22 mm ID × 22 mm OD). Connect the Adaptive Sensor to the inlet end of Gas Injection Adapter (22mm ID × 22 MM OD).	NOTE
		For detailed Injection Assembly with Adaptive Sensor instructions, refer to Section 3.4.1 . If an Inline Mixer is required per Table 6, refer to Section 3.4.2 for instructions to assemble and then proceed to Step 2.
	Attach the Injection Assembly with Adaptive Sensor to the Gas Injection Adapter on the Inspiratory Port on the AGM.
	Attach the inspiratory limb of the breathing circuit to the Inline Breathing Circuit Filter. If the breathing circuit has a Sample Gas Tee inserted, ensure this limb of the circuit is attached to the Inline Breathing Circuit Filter.
	Insert the Gas Sample Tee into the inspiratory limb of the breathing circuit, 6-12" from the patient wye.	WARNING
		Ensure the Injection Assembly and the Gas Sample Tee are BOTH inserted on the inspiratory limb of the circuit.
		NOTE
		Skip this step if a Gas Sample Tee is already connected and in-line with the circuit.
	Insert an Inline Breathing Circuit Filter between the Expiratory Port and expiratory limb. Skip this step if a bacterial filter is already present in the expiratory limb of the breathing circuit.	NOTE
		Skip this step if a bacteria filter is already connected and in-line with the circuit.
	Attach the expiratory limb of the breathing circuit to the Inline Breathing Circuit Filter on the Expiratory Port on the Anesthesia Machine
	Push and twist clockwise the luerlock collar from the NO injection line onto the NO injection port of the Gas Injection Adapter on the Injection Assembly.
	Push and twist clockwise the Luer-Lock Collar of the Stopcock on the Sample Line onto the Sampling Port of the Gas Sample Tee.	NOTE
		Refer to Section 4 for Console Start up instructions and Section 5 for nitric oxide administration instructions.
	Connect the distal end of the Adaptive Sensor Cable to the Adaptive Sensor on the Injection Assembly
Refer to Section 3.6 for connection instructions of the GENOSYL DS to a manual bagging system.

NOTE

When using the manual ventilation bag integrated with the AGM, nitric oxide can be delivered by leaving the Console in Primary Dosing Mode. Nitric oxide will be delivered through the Injection Assembly into the anesthesia gas circuit.
In the event of anesthesia gas machine failure, NO delivery can be continued using Manual Dosing Mode on the GENOSYL DS with a manual bag connected to the manual ventilation port on the front of the Console and an alternative gas source than the AGM. Refer to Section 3.6 for GENOSYL DS connection instructions and Section 5.4 for GENOSYL DS Manual Dosing Mode operating instructions.

The GENOSYL DS features a leak detection tool to inform the user that there may be a suspected leak in the GENOSYL DS circuit. The information will be displayed on the "Alarms" tab as pictured in Figure 35 . This feature is only available when an Adaptive Sensor is connected in the GENOSYL DS circuit. A leak is suspected if there is a difference between the flow measured by the Adaptive Sensor and estimated flow of the GENOSYL DS injection algorithm. This feature is a diagnostic tool only and the device is properly functioning and delivering NO, even when a leak is detected. However, a leak may result in a decreased Cassette life and should be addressed to ensure optimum Cassette life performance. Refer to Section 10.8 Troubleshooting for recommended actions to address a suspected leak.

11. SYSTEM MAINTENANCE

11.1 Calibration

This section describes the process for performing high and low calibration for NO, NO _2,and O ₂. Calibration of the GENOSYL DS should be performed every 28 days to ensure the accuracy of NO, NO ₂, and O ₂measurements. All calibrations can be performed at any time the Console is powered on, including while actively dosing. Air calibrates the low range for the NO and NO ₂sensors. The high range of the NO and NO ₂sensors are calibrated by using calibration gas tanks. The software will notify the user when calibration is due.

The display within the "Calibration" tab provides the status and the calibration due date of the different types of sensors. Air calibration provides the time of the last calibration since the System automatically performs this calibration every 4 hours while actively dosing or every 24 hours while powered on. A green check under status indicates that sensor has successfully been executed within the calibration period. A red X under status indicates that the sensor has not successfully been executed within the calibration period.

During calibration, the display will provide measured readings from each sensor. Note, there are two redundant NO sensors which are used to verify and ensure accuracy of the dosage provided by the System. During calibration, the display will provide a real-time status of the test with colored boxes to the right of the displayed sensor output. A yellow box indicates that the sensor is being calibrated. A green box indicates that calibration was successful for that sensor. A red box indicates that calibration for that sensor failed.

WARNING

ONLY use the calibration gas pressure regulators supplied by the manufacturer. Pressure regulators not supplied by the manufacturer may damage the sensors and may lead to patient injury.
ALWAYS verify the correct NIST traceable calibration gas is being used and confirm the expiration date of the calibration gas prior to performing calibration. The use of incorrect or expired gas may result in inaccurate sensor readings and can lead to patient injury.
NEVER perform NO or NO ₂calibration within the MR scanner room. Calibration equipment is a potential projectile hazard.

CAUTION
ALWAYS perform a full-scale calibration of the GENOSYL DS when prompted by the System prior to use. ALWAYS confirm the correct flow direction of the installed one-way check valve in the sampling tee to avoid over pressurization of the sample system and damage to the device.

GENOSYL ^®DS

SECTION 12
MECHANICAL VENTILATION

12. MECHANICAL VENTILATION

WARNING
ONLY mechanical ventilators validated with the GENOSYL DS should be used. Not using a validated ventilator system can result in injury or harm. DO NOT use the GENOSYL DS with circle anesthesia ventilator systems. The GENOSYL DS has not been characterized or qualified for use with anesthesia breathing systems with recirculation of gases.

12.1 Mechanical Ventilation

There are two main effects of connecting the GENOSYL DS to a ventilator breathing circuit:

The System injects up to 0.9 LPM of NO/air (21% Oxygen) into the inspiratory output of the ventilator.
The System samples up to 0.3LPM from the ventilator circuit as a measurement to the built-in gas analyzers

The results of adding and subtracting gas into the ventilator circuit are described in sections 12.1.1 to 12.1.4:

12.1.1 Oxygen Dilution

The ventilator typically is flowing gas to the patient with enhanced oxygen content from room air, ranging from 21% at 100% oxygen. The DS is injecting NO mixed with air with a concentration of oxygen at nominally 21%. Thus, except for the case where the ventilator is supplying gas to the patient at 21% oxygen, there is some dilution of the oxygen delivered to the patient.

This dilution may be determined with the following equation:

Percent O ₂to Patient = [{%O ₂/100 + (Flow _inj/Flow _vent)×0.21}/{1 + (Flow _inj/Flow _vent)}]×100

Where:

Flow _inj= Injection flow in same units as ventilator flow
Flow _vent= Ventilator flow in same units as injection flow
%O ₂= Percent oxygen out of ventilator
0.21 = Fraction of oxygen in injection flow (21%)

Table 12 below shows the maximal dilution effect on the concentration of oxygen supplied to the patient for set ventilator flow settings with NO doses ≤40 ppm and a nominal flow from the GENOSYL DS of 0.6 LPM of NO/air (21% oxygen) into the inspiratory output of the ventilator. Actual dilution may vary based on respiratory device settings and clinical scenarios.

This is applicable for all compatible gas delivery systems, unless otherwise noted below.

NOTE
The following respiratory devices demonstrated oxygen dilution that is representative of in ection flow greater than 0.6LPM in testing with NO doses ≤ 40 ppm. Use the calculation above to estimate maximal dilution using Flowinj = 0.64 LPM: Bio-Med Devices MVP-10

Table 12: Oxygen Dilution
Oxygen (%) Supplied from Ventilator
100	80	60	40	21
Ventilator Flow (LPM)	Oxygen (%) Delivered to Patient
70	99	79	60	40	21
20	98	78	59	39	21
15	97	78	59	39	21
10	96	77	58	39	21
9	95	76	58	39	21
8	94	76	57	39	21
7	94	75	57	39	21
6	93	75	56	38	21
5	92	74	56	38	21
4	90	72	55	38	21
3	87	70	54	37	21
2	82	66	51	36	21
1	70	58	45	33	21
0.5	57	48	39	30	21

Higher injection flows may be employed by the GENOSYL DS when administering NO doses >40 ppm. Use injection flow of 0.9 LPM to estimate the maximal dilution effect on the concentration of oxygen supplied to the patient when administering NO doses >40 ppm.

12.1.2 Minute Volume

When using volume ventilation with the GENOSYL DS, the tidal volume delivered to the patient may show small changes due to the addition and subtraction of gases by the Delivery System. Some minor ventilator adjustments to the minute volume may be required. Maximum total flow added to the ventilator circuit is 0.9 LPM of concentrated NO gas and the maximum total flow removed from the ventilator circuit is 0.3 LPM of sampled gas.

12.1.3 Trigger Sensitivity

The addition and subtraction of gases by the GENOSYL DS may affect the trigger sensitivity of the ventilator when using synchronized modes of ventilation. This may cause ventilators which have flow trigger modes to auto-cycle or result in apnea alarms, especially where the trigger flow is less than the total flow added.

12.1.4 Maximum NO Delivery

The maximum combination of dose (ppm) and flow (LPM) is 800 ppm × LPM (e.g., 20 ppm with 40 LPM, 40 ppm at 20 LPM, etc.). The System is capable of delivering NO at a minimum of 1 ppm × LPM (e.g., 1 ppm at 1 LPM). See the graph below for the minimum and maximum dose ranges for the System, based on ventilator circuit total minute volume.

12.1.5 Bias Flow and NO ₂

The GENOSYL DS has a safety fallback where the delivery of nitric oxide will be interrupted when a sampled value higher than 3 ppm NO ₂is detected. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose. The table below outlines the dose at which a delivery interruption was observed during validation testing in a laboratory setting due to high NO ₂. For validation testing, FiO ₂was set at 100% and the maximum bias flow setting for each ventilation device was used. If there is an unexpected change in NO ₂concentration, the delivery system should be assessed in accordance with the recommended actions for troubleshooting Section 10.8 , and the NO ₂analyzer should be recalibrated. The dose of GENOSYL and/or FiO ₂should be adjusted as appropriate.

CAUTION

When using spontaneous breathing modes on respiratory device, NO ₂levels may exceed 3.0 ppm when dosing ≥ 57 ppm NO into 100% FiO ₂and maximum bias flow, resulting in nitric oxide delivery interruption. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose. Refer to Section 12.1.5 Table 13 for additional information.
When using non-spontaneous breathing modes on respiratory device, NO ₂levels may exceed 3.0 ppm when dosing ≥ 63 ppm NO into 100% FiO ₂and maximum bias flow, resulting in nitric oxide delivery interruption. Once sample value of NO ₂is below 3.0 ppm, the Console will auto resume delivery of NO at set dose. Refer to Section 12.1.5 Table 13 for additional information.

12.2 Ventilator Compatibility

VERO Biotech performs validation testing which determines the compatibility of ventilator/gas delivery systems with the GENOSYL DS. During this compatibility testing, the GENOSYL DS is evaluated for the following parameters while connected to each ventilator/gas delivery system:

NO Dose Accuracy: Continuous and accurate delivery of a targeted dose of nitric oxide within ± 20% of setpoint or within ± 2 ppm, whichever is greater.
Respiratory Device Breath Delivery and Alarms: The respiratory device breath delivery and alarms continue to function as intended by the manufacturer across the range of operating conditions.
NO ₂Performance: NO ₂remains within acceptable limits less than 1.0 ppm with 60% FiO ₂and ≤40 ppm NO.
O ₂Dilution: Post dilution O ₂level delivery is maintained within acceptable limits and conforms with the information presented in the GENOSYL DS Operator's Manual, Section 12.1.1 , "Oxygen Dilution".
NO Concentration Transients: NO concentration transients are ≤150% of mean concentration and as low as 0.0 ppm as long as the transient duration does not exceed 10% of the volumetric duration of the breath.

The testing performed demonstrated conformance with all specified requirements. The following ventilators and non-invasive gas delivery systems in Table 14 have been validated for use with the GENOSYL DS. See Section 3.2 for use configurations.

WARNING

MR image artifact was evaluated using 1.5 T and 3 T MRI Systems. Testing was conducted using standard American College of Radiology (ACR) sequences and a standard ACR large phantom placed inside a transmit-receive head coil. Duplicate sequences were performed to acquire the same images with and without the GENOSYL DS operating on battery power inside the MRI suite.

The GENOSYL DS compatibility test results are as follows:

Artifact Dimensional Analysis	1.5 T	The maximum dimensional change in images acquired during the operation of the GENOSYL DS was < 1 mm.
Artifact Dimensional Analysis	3 T	The maximum dimensional change in images acquired during the operation of the GENOSYL DS was < 1 mm.
Image Quality Signal-to-Noise Ratio Analysis	1.5 T	The average SNR change was -35%. The average SFNR change was -42%. The PIU values were all 96%.
Image Quality Signal-to-Noise Ratio Analysis	3 T	The average SNR change was -25%. The average SFNR change was -22%. The PIU values were all greater than 94%.

The GENOSYL DS does not distort the geometric accuracy and the image intensity uniformity is not adversely affected by the presence of the GENOSYL DS at the 100 Gauss line. The SNR and SFNR are both impacted by the presence of the GENOSYL DS, to a more pronounced degree when the equipment is powered via a wall outlet inside the MRI suite versus operating on the battery.

NOTE
The test results presented here were obtained with the GENOSYL DS operating on battery power. If using the GENOSYL DS while connected to wall power, it is recommended to route the power cords through a waveguide.

Conducted RF IEC 61000-4-6	6 V rms 150 kHz to 80 MHz in ISM bands The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.	10 V 80% AM @ 1 kHz 150 kHz - 80 MHz in ISM bands,	Except as indicated on page 10-137, portable and mobile RF communications equipment, including cables, should be used no closer to any part of the GENOSYL DS than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance: d=1.2√P d=1.2√P d=1.2√P 80 MHz to 800 MHz d=2.3√P 800 MHz to 2.7 GHz where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.7 GHz are intended to decrease the likelihood that a portable communications device could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, Field strengths from fixed transmitters, such as base stations for radio (cellular cordless) telephones and land mobile radios, amateur radio, AM and F M radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed R transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the GENOSYL DS is used exceeds the applicable RF compliance level above, the GENOSYL DS should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the GENOSYL DS. should be less than the compliance level in each frequency range. Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m. Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE
NOTE 1 : At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

Recommended separation distances between portable and mobile RF communications equipment and the GENOSYL DS
The GENOSYL DS is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the GENOSYL DS can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the GENOSYL DS as recommended below, according to the maximum output power of the communications equipment except as indicated on page 10-166.

Mechanism of Action

Nitric oxide relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase, activating guanylate cyclase and increasing intracellular levels of cyclic guanosine 3',5'-monophosphate, which then leads to vasodilation. When inhaled, nitric oxide selectively dilates the pulmonary vasculature, and because of efficient scavenging by hemoglobin, has minimal effect on the systemic vasculature.

GENOSYL appears to increase the partial pressure of arterial oxygen (PaO ₂) by dilating pulmonary vessels in better ventilated areas of the lung, redistributing pulmonary blood flow away from lung regions with low ventilation/perfusion (V/Q) ratios toward regions with normal ratios.
