Prepare the AeroNOx
Transport Nitric Oxide
Titration & Monitoring System
for initial operation as follows:
1. Unpack the AeroNOxand inspect for damage.
2. Install battery as per SECTION III, “Battery”.
3. Unpack 12 V universal power supply (P/N 293-0040) and Medical Grade Power Cord
(P/N 711-0179). Plug in AeroNOxand charge for ~ 24 hrs.
4. Calibrate AeroNOx. (See SECTION V.)
5. Attach CGA 626 regulators to the transport tanks as per “Purge procedures to follow
when changing tanks and/or regulators” in this section.
6. Connect selected regulator outlet to the AeroNOxgas inlet using the stainless steel hose
with quick connect adapters.
7. Turn on nitric oxide gas supply.
8. Attach the delivery line from the AeroNOxBagger (See Diagram # 2) or the AeroNOx
delivery line (P/N 415-0001) found in the AeroNOx“NO WORRIES” connector sample
pak to the female luer connector marked “NITRIC OXIDE DELIVERY OUTLET” on the
AeroNOx. Tee the other end of the delivery line into the patient breathing circuit at least
30 - 40 cm upstream of the sampling site (see Diagram # 1).
9. Attach the “NO WORRIES” sample line (P/N 415-0004) to the male luer connector
marked “ANALYSIS SAMPLE INLET” on the AeroNOx.
10. Select the appropriate sample gas connector from your “NO WORRIES” connector
sample pak and attach it to the free end of the sample line. *NB if attaching the sample
line to the bagger, skip this step.
11. Connect the sample gas connector to the patient breathing circuit. The connector should
be placed in the inspiratory limb, just prior to the patient wye connection (refer to Diagram
# 1).
OR
Connect the sample line to the sampling port on the bagger (see Diagram # 2).
12. “Flush” your system according to “Suggested flush procedure for the delivery portion of
the AeroNOxsystem”, or according to the instructions for the AeroNOxBagger.
13. You are now ready to deliver NO gas and sample mixed inspired gases.
CAUTION!
Never turn on the NO delivery gas without first turning on the
ventilator or bagger flow. Failure to do this will result in undiluted
delivery gas entering the sampling chamber and exposing the
sensors to levels of NO and/or NO2which may damage the
sensors.
CAUTION!
NO2gas may have collected in the AeroNOxdelivery circuitry. Prior
to delivering gas to the patient, “flush” your delivery system with
fresh NO delivery gas. This should be repeated every time you begin
NO gas administration. Analyze the gas for high NO2levels prior to
patient connection.

Document No. 715-7000 Revision E Page 9 of 63
Suggested “flush” procedure for the delivery portion of the AeroNOxsystem:
1. Set up the AeroNOxfor delivery as outlined in “AeroNOxTransport Nitric Oxide
Titration & Monitoring System for initial operation”.
2. Hook up the ventilator to a test lung (patient should be manually ventilated during this
procedure and the ventilator parameters should be set to the patient’s pre-NO gas
settings).
3. Inactivate the “Safety Shut Off” system by simultaneously depressing the NO and NO2
alarm silence buttons for 5 seconds or until the display reads “SAFETY OFF”. For more
information on the “Safety Shut Off” system, see “Safety Shut Off” in SECTION III.
4. Turn on the NO gas flow to 2 lpm by turning the knob on the precision metering valve in a
counter-clockwise direction. This knob is located in the bottom right hand quadrant of the
front panel of the AeroNOxbelow the LCD flow display. Allow the gas to flow into the
ventilator circuit.
5. As soon as the NO2value has dropped to a stable level, allow the gas to run for an
additional 3 seconds and then adjust the NO flow to the desired level (see SECTION VII -
Calculations for NO Delivery to determine flow required for desired NO concentration).
6. Re-activate the “Safety Shut Off” system by simultaneously depressing the NO and NO2
alarm silence buttons for at least 5 seconds or until the display reads “SAFETY ON”.
7. Once the desired NO concentration has been reached, ensure that NO2level is
acceptable for patient administration. Below you will find a table which will give you the
approximate NO2values you can expect for a given NO concentration and ventilator flow
at an FiO2of 1.0.
Minute Volume / Ventilator Flow
[NO] 5 10 15 20
5 ppm 0.5 0.1 0.1 0.1
10 ppm 0.5 0.2 0.2 0.1
20 ppm 0.5 0.3 0.2 0.2
40 ppm 0.8 0.6 0.4 0.4
80 ppm 2.0 1.5 1.2 1.1
NO2in PPM
The table above is for reference only.
Factors such as the accuracy of the ventilator flow, percent error in delivery apparatus,
and human error, may all affect the actual delivered patient dose. The calculated NO flow
should be compared with the analyzed NO dose to confirm accurate NO dosing. Should
the actual NO flow differ from the calculated NO flow by more than 10% beyond
published specifications, the cause must be determined and corrected immediately. If the
cause can not be immediately determined, ensure patient safety and contact International
Biomedical at 1-800-433-5615 for further assistance.
8. Connect the patient to the ventilator and monitor according to study and/or institution
protocol.
CAUTION!
The flush procedure must be performed each time NO therapy is
started. This includes initial therapy starts, tank changes, and re-
starting therapy after trials off NO.

Document No. 715-7000 Revision E Page 10 of 63
Purge Procedures to follow when changing tanks and/or regulators.
Important!
Purge Procedure Required before Use
Please follow purge instructions below to ensure gas purity. Failure to follow these
instructions may introduce potentially harmful contaminants into the patient’s
breathing gas or may affect the monitoring analyzer’s accuracy by introduction of
contaminants into the calibration gas.
Warning:Perform cylinder connection and purge procedures in well-ventilated areas
to prevent inadvertent exposure to nitric oxide or nitrogen dioxide gas. Follow your
facility’s safety procedures for handling medical gas cylinders.
Purge Procedures for use with Medical Gas Regulators:
1. Connect cylinder to a matching CGA nitric oxide or nitrogen dioxide
regulator only.
2. Open, then immediately close the cylinder valve.
3. Release (bleed) all of the gas from the regulator.
4. Repeat steps 2 and 3 four more times for a total of five purge cycles.
5. Leave the regulator installed until it is time to change to a new cylinder.
6. Repeat the purge procedure any time a regulator is reattached.
Any time a regulator is installed on a tank or cylinder of compressed gas, certain precautions
must be followed. This is to prevent contamination of the gas in the tank and in the system by
air that is trapped in the dead space of the regulator and fittings. To eliminate the possibility of
the oxygen in this air reacting with the nitric oxide to form nitrogen dioxide in the system, the
regulator and fittings must be purged before use. The valve on the tank must not be opened
and left open until the regulator is purged. The stainless steel line must also be purged prior to
connection to the AeroNOx.
CAUTION!
Should there be a sudden need to change therapy tanks, a second tank
should always be purged and ready for immediate use. Perform the
purge procedure immediately upon installation of a new regulator.
Although the dead space volume in the regulator and hose assembly is physically small, if it had
been exposed to room air for a period of time it will contain sufficient oxygen to convert a
significant amount of nitric oxide to nitrogen dioxide.

Document No. 715-7000 Revision E Page 11 of 63
The following purge procedure must be followed any time a regulator is installed on a tank of
gas. It should be done immediately after connecting a regulator to a tank to avoid contaminating
a tank of gas with the air trapped in the dead space of the regulator in the event someone turns
on and leaves on the valve on the tank.
1. Install and tighten the regulator onto the tank.
2. Insert the quick-connect on one end of the stainless steel hose into the quick-connect
fitting on the regulator. Leave the other end of the stainless steel hose free.
3. Crack open and immediately close the tank valve.
4. Gently press the center tip of the quick-connect on the free end of the stainless steel hose
against a clean hard surface and allow the pressure to bleed to zero. A small amount of
high concentration delivery gas will be released at 50 psig. Keep the hose away from
patients and clinicians in order to avoid exposure to the gas.
5. Repeat Step 3 and Step 4 above five times (five complete purge cycles).
6. Connect equipment and open the tank valve as needed.
Any time a regulator is installed onto a cylinder and before each patient use, the
AeroNOxsystem should be purged. - NO EXCEPTIONS!!
AeroNOxBagger: Instructions for use with the AeroNOx
(See Diagram # 2.)
CAUTION!
Oxygen and Nitric Oxide mix in the reservoir bag and stagnant flow will cause NO2to be
formed. Turn off NO flow when not actively bagging patient. Flush the bagger with
oxygen for a least 20 seconds to completely remove NO and NO2before and after patient
use.
Concentrations of nitrogen dioxide in the reservoir bag may exceed 1 ppm. Large tidal
volumes may expose patients to the nitrogen dioxide in the reservoir bag.
Flush the bagger with oxygen for at least 20 seconds to completely remove NO and NO2
after any interruption in active patient bagging.
The AeroNOxmay not be able to detect rapid, short acting fluctuations in the
concentration of the delivered gas, including nitrogen dioxide. For this reason, the
AeroNOxBagger is designed for short-term use only.
If a patient requires nitric oxide concentrations other than 20 ppm, a separate system
capable of providing the required concentration must be available. DO NOT USE THE
AERONOXBAGGER TO DELIVER CONCENTRATIONS IN EXCESS OF 20 PPM!
The generation of nitrogen dioxide increases rapidly above this concentration.
Do not alter the length of the Bagger Gas Supply Tubing as this may cause generation of
excessive levels of nitrogen dioxide.

Document No. 715-7000 Revision E Page 12 of 63
Do not substitute AeroNOxBagger components! The AeroNOxBagger has been
designed and tested for patient safety with the components included in the current
configuration.
The AeroNOxBagger is designed for use only with the AeroNOxDelivery System. Do
not attempt to use the AeroNOxwith any other manual resuscitator. Do not attempt to
use the AeroNOxBagger with any other delivery system.
A backup system must always be available in the event that the primary system should
fail. For instructions for use of a Back-Up System in the event of a failure of the
AeroNOxsystem, please see SECTION III, Back-Up system.
The AeroNOxBagger is intended to be connected directly to the patient’s endotracheal
tube. Do not insert any additional tubing between the AeroNOxBagger and the
endotracheal tube.
The AeroNOxBagger is for single patient use only. Do not reprocess.
Persons using this device should be trained and experienced in the use of this device to
assure affective administration of nitric oxide, and to avoid injury to the patient or to
others resulting from inhalation of excess nitric oxide, nitrogen dioxide, or other reaction
products.
Persons using this device who may be particularly sensitive to nitric oxide, or who may be
exposed to these gases for prolonged periods as a result of the use of this device, should
be aware that the gases exiting the AeroNOxBagger are not scavenged.
1. Connect the large end of the bagger gas supply tubing to an oxygen source. Ensure that
the small end of this tubing is connected to the NO / O2gas inlet port on the bagger.
2. Connect AeroNOxBagger gas delivery line to the AeroNOxdelivery gas port.
3. Connect male end of the sample line (P/N 415-0004) to the sampling port on the bagger
gas supply tubing and the female end to the AeroNOxsampling port.
4. Set O2flow on the O2flow meter to exactly 10 LPM. Let the oxygen run for at least 20
seconds to flush out any residual NO or NO2left in the AeroNOxBagger.
5. Turn on NO delivery gas source to 0.25 LPM. If you have correctly set your O2flow at
exactly 10 LPM, the delivered NO concentration will be ~20 ppm and delivered NO2
values should not exceed 0.2 ppm. Do not exceed 20 ppm during manual ventilation!
6. Connect test lung and set overflow valve to desired positive end expiratory pressure
(PEEP).

Document No. 715-7000 Revision E Page 13 of 63
7. Continue to run the AeroNOxBagger with the test lung until the analyzed NO and NO2
values stabilize. This will prevent high doses of NO2, which can form in the bagger and
delivery line, from being delivered to your patient. The NO2sensor in the AeroNOx
Bagger may not react quickly enough to detect NO2boluses.If you do not have time
to use a test lung, in an emergency situation for example, you must still flush the
bagger with fresh gas for at least 20 seconds prior to patient connection!
8. Analyze NO and NO2concentration prior to patient administration.
9. Flush bagger with O2after each patient use to flush out residual NO and prevent
NO2formation.
