WARNING: Integrated Pneumatic Backup
• The integrated pneumatic backup is intended for short term use when the electronic delivery system fails until a replacement NO delivery device can be brought to the bedside. • The integrated pneumatic backup delivers a variable concentration of NO to the patient depending on the ventilator flow being used. • When using the integrated pneumatic backup with breathing circuit gas flows of 5 L/min, the delivered NO dose will be approximately 40 ppm. Breathing circuit gas flows less than 5 L/min will deliver an NO dose greater than 40 ppm.
Changing Cylinders • Only use manufacturer supplied drug cylinders, regulators and adapters (see Changing INOMAX Cylinders and Purging the Regulator Assembly, Section 3/ Patient Application). • Cylinders should be stored between 59-86 degrees F (15-30 degrees C). • Always secure a cylinder when not using it. • Never lift a cylinder by its valve. • Never drop a cylinder. • Never use a hammer, pry or wedge to loosen a valve or protection cap. The valve and protection cap should be operated by hand. • Never let oil, grease or other combustibles come in contact with a cylinder or valve. • Never remove or deface cylinder labeling or markings. • Never attempt to repair a leaking cylinder valve or its safety relief device. • Never operate equipment that is leaking. • Never ship a leaking cylinder. • Never store cylinders: - where damage can result from the elements, such as standing water or temperatures over 125 degrees F (52 degrees C). - where they can contact corrosive substances. - where they can be cut or abraded by an object. - next to a walkway, elevator or platform edge.

WARNING:
Maintenance • Handle and dispose of sensors according to facility biohazard policies. Do not incinerate. • If the MR injector module has been used in the wet/humidified part of the breathing circuit, it should be sterilized between each patient use. • Do not use the RS 232 data output while in the MR scanner room. • Use only RS 232 cables that are shielded (see Section 7/ Product Specifications for more detail). • Keep the test magnet tool away from pacemakers, ICDs and other implanted medical devices.
Manually Bagging a Patient with a MR Injector Module • Do not place the injector module in-line with a manual resuscitation bag.
Manually Bagging a Patient with the INOblender
• The purge procedure must be followed to help ensure NO2 is purged from the system before the manual resuscitator bag is connected to the patient. • The manual bag should be squeezed repeatedly during use to avoid NO2 building up in the bag. • If the bag is not squeezed repeatedly while delivering INOMAX, the bag should be removed from the patient and the bag purge procedure performed before continuing. • The INOblender should be upright when setting the oxygen flowrate for accurate setting. • Do not use pneumatically powered nebulizers with the INOblender. This will result in significant over delivery of INOMAX in excess of 80 parts per million (ppm). - The INOblender outlet pressure has been validated for use up to 400 millibar (5.8 psig) pressure. The amount of back-pressure generated by pneumatic nebulizers is significantly greater (20-30 psig) and will result in over delivery of INOMAX in excess of 80 ppm. The user adjusted dose setting on the INOblender will not correlate with, or have an effect on the actual delivered dose. - In addition, the INOblender flowmeter is not back-pressure compensated and will display a lower flow rate than actual when pressure is applied to the outlet.
Purging the INOmax DSIR Plus MRI
• All INOmax DSIR Plus MRI devices must be purged before use to ensure the patient does not receive an excess level of NO2. • If the INOmax DSIR Plus MRI is not going to be used on a patient within 10 minutes, depressurize the regulator supply line. • If the INOmax DSIR Plus MRI is not used and is pressurized for more than 10 minutes, repeat automated or manual purge procedure. • If the INOmax DSIR Plus MRI is depressurized and not used within 12 hours, repeat pre-use procedure.

WARNING:
Troubleshooting or Calibrating • If an alarm occurs, safeguard the patient first before troubleshooting or repair procedures. • Abrupt discontinuation of INOMAX may lead to worsening oxygenation and increasing pulmonary artery pressure, i.e., Rebound Pulmonary Hypertension Syndrome. To avoid abrupt discontinuation, utilize the INOblender or integrated pneumatic backup if necessary. If Rebound Pulmonary Hypertension occurs, reinstate INOMAX therapy immediately. (See the INOMAX prescribing Information for further details). • If the high NO2 alarm activates, the delivery system should be assessed for proper setup while maintaining INOMAX delivery. Adjust INOMAX and/or FiO2 as appropriate. (See INOMAX Prescribing Information for further details on the effects of Nitrogen Dioxide, NO2). If unable to determine the cause of the increased NO2 levels, call technical support and do not discontinue therapy. • Use caution when troubleshooting the INOmax DSIR Plus MRI while in use for a patient. When possible, replace the unit in question and perform troubleshooting procedure once the unit is removed from the MR scanner room. • Do not perform a high calibration procedure in the MR scanner room. Calibration equipment is a potential projectile hazard. • Do not remove rear sensor cover in the MR scanner room due to potential projectile hazard. • Do not change any sensor while delivering NO to a patient. • Loss of communication between the INOmax DSIR Plus MRI and the INOMAX cylinder for more than one hour will result in interruption of INOMAX delivery.
Use in a MR Environment
• A strong magnetic field such as that from an MRI system can affect the ability of the INOmeter to detect if the cylinder valve is open. This can cause a “Cylinder Valve Closed” alarm to occur when the cylinder valve is actually open. If this alarm occurs, reposition/rotate the INOmax DSIR Plus MRI cart outside the 100 Gauss area to reduce the magnetic interference in the area of the INOmeter until the cylinder handle graphic on the display turns green. This will resolve the “Cylinder Valve Closed” alarm. Typically the required INOmax DSIR Plus MRI cart location adjustment is less than 6 inches (15 cm) / 90 degrees. Note that Interruption of INOMAX therapy will occur one hour from point when the “Cylinder Valve Closed” alarm is activated if the alarm is not resolved. • Only use a size “88” (1,963 liters) cylinder that is marked “MR Conditional. Keep cylinder at 100 gauss or less.” with the INOmax DSIR Plus MRI while in the scanner room. Use of any other cylinder may create a projectile hazard. • The INOmax DSIR Plus MRI 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. • This device contains ferromagnetic components and hence will experience strong attraction close to the magnet. It should be operated at a fringe field of less than 100 gauss. • Do not exceed 100 gauss; system operation may be impacted. Confirm cart auto-brake function. Optionally connect tether. • Verify at least one gauss alarm is functioning properly prior to use. • Do not use the INOmax DSIR Plus MRI if neither gauss alarm is functional.
Part No. 20568 Rev-01 2015-08
v
WARNING: Use in a MR Environment continued
• The gauss alarm will sound if the INOmax DSIR Plus MRI system is too close to the MR scanner. If alarm sounds, move system away from the MR scanner until the gauss alarm stops sounding. • Always verify that the INOmax DSIR Plus MRI auto-brake is engaged after positioning in the MR scanner room. • Always verify that the INOmax DSIR Plus MRI and INOblender are securely attached to the cart. • Never attach an oxygen cylinder to the INOmax DSIR Plus MRI cart. • Arrange power cord, MR patient gas sample line, MR injector tubing and MR injector module cable to avoid entanglement, strangulation and/or a trip hazard. • If the cart fails to move when the brake handle is pulled, or moves when the brake handle is not pulled, do not use the INOmax DSIR Plus MRI and contact your local representative.
Use Outside of Product Labeling • The INOmax DSIR Plus MRI must only be used in accordance with the indications, usage, contraindications, warnings and precautions described in the INOMAX (nitric oxide) drug package inserts and labeling. Refer to this material prior to use. • Outside of the United States, use of the INOmax DSIR Plus MRI is limited to the use in accordance with INOMAX nitric oxide for inhalation prescribing information as established with the national health authority. • Helium/oxygen mixtures should not be used with the INOmax DSIR Plus MRI. • The use of devices which radiate high-intensity electrical fields may affect the operation of the INOmax DSIR Plus MRI. Constant surveillance of all monitoring and life support equipment is mandatory whenever interfering devices are in operation on or near a patient. • The target patient population is controlled by the drug labeling for INOMAX and is currently neonates. The INOmax DSIR Plus MRI is not intended to be used in other patient populations.
Ventilators and Breathing Devices • The INOmax DSIR Plus MRI subtracts gas from the breathing circuit via the gas sampling system at 230 mL per minute which can cause the ventilator to autotrigger. Adjusting the flow sensitivity may be necessary. The trigger sensitivity of the ventilator should be checked after connecting the INOmax DSIR Plus MRI to the breathing circuit. • Set the INOmax DSIR Plus MRI alarm thresholds for the current patient conditions to monitor any inadvertent changes in treatment. • Be certain all cables and hoses are positioned to help prevent damaging or occluding them. • The use of pediatric and neonatal ventilator settings with adult size breathing circuits can result in higher levels of NO2. Always use the size of breathing circuit that is appropriate for the patient. • The humidifier chamber volume should not be more than 480 mL to minimize elevated NO2 values. • The patient gas sample tee must have the INOmax DSIR Plus MRI sample line attached or be capped off to avoid loss of ventilator circuit pressure. • Only use parts/accessories designated for use with this system.

GaussAlert™ (gauss alarm) WARNING:
Verify at least one gauss alarm is functioning properly prior to use. Do not use the INOmax DSIR Plus MRI if neither gauss alarm is functional.
GaussAlert Features: The GaussAlert is designed to help keep the INOmax DSIR Plus MRI outside of the MR exclusion zone. The GaussAlert is programmed to alarm when the preset magnetic field strength is exceeded. It produces a distinct audio alarm when the INOmax DSIR Plus MRI is placed too close to the MR scanner bore. • When the equipment to which GaussAlert is attached is exposed to a magnetic field strength greater than GaussAlert’s set alarm threshold (100 gauss), a loud and piercing whoop tone will sound continuously as long as the unit remains in the exclusion zone. • The alarm will cease when the INOmax DSIR Plus MRI is moved away from the scanner bore to a location where the magnetic field strength is less than the alarm trip point (100 gauss). Additional Information: • The GaussAlert functionality should be checked monthly (see Section 6/Maintenance). • Mallinckrodt will provide all maintenance for the GaussAlert.
