GENERAL INFORMATION
1.1.
Introduction
This manual describes the theory of operation, frequently used features, safety
considerations, specifications, and maintenance for the AeroNOx 2.0 nitric oxide (NO)
delivery system. Each AeroNOx 2.0 provides the basic equipment required for NO
delivery and accessories are available to accommodate specific installations.
The AeroNOx 2.0 system includes an integrated nitric oxide gas delivery system and
nitric oxide (NO), nitrogen dioxide (NO2), and oxygen (O2) analyzer. The AeroNOx 2.0
is a stand-alone, lightweight, portable unit designed to continuously monitor NO, NO2,
and O2 concentrations in a breathing circuit.
The AeroNOx 2.0 system is specifically designed for the delivery and monitoring of
gaseous nitric oxide (NO) in parts per million (ppm) concentrations.
The AeroNOx 2.0 is designed for use within a hospital or during patient transfer via
rescue vehicle, fixed wing aircraft, or helicopter.
1.2.
Intended Use
The AeroNOx 2.0 is intended to provide a constant controlled concentration of nitric
oxide in breathing gas by delivering a constant controlled flow of nitric oxide into the
inspiratory limb of a mechanical ventilator that operates using a continuous constant flow
of fresh gas into the inspiratory limb of the ventilator. The AeroNOx 2.0 is also
intended to be used with a flow inflating manual ventilator (an AeroNOx 2.0 accessory),
by introducing controlled flows of nitric oxide into the fresh gas flow to the manual
ventilator. It is also intended to monitor nitric oxide, nitrogen dioxide, and oxygen
concentrations in the breathing gas.
The AeroNOx 2.0 is intended to be used within a hospital or during air or ground
transport outside the hospital.
1.3.
1.4.
Medical Indication
Nitric oxide therapy is intended to treat late pre-term neonates ( 34 weeks gestation,
< 14 days of age) diagnosed with Persistent Pulmonary Hypertension of the Newborn
(PPHN) described as:
a.
A failure to achieve transition to air breathing due to a lung parenchymal disease
such as meconium aspiration syndrome, pneumonia, or infant respiratory distress
b.
Idiopathic PPHN in which the lung parenchyma is normal but the pulmonary
vasculature has been remodeled
c.
Documentation of pulmonary hypertension by a pediatric cardiologist
Contraindication
The only contraindication for inhaled nitric oxide therapy is neonates dependent on rightto-left shunting of blood. Always refer to the inhaled Nitric Oxide Gas prescribing
information sheet.

The AeroNOx 2.0 must be used in accordance with indications, usage, contraindications, warnings,
and cautions described in this manual.
The use of devices which radiate high intensity electrical fields may affect the operation of the
AeroNOx 2.0. Constant assessment of the patient and all life support equipment is mandatory
whenever interfering devices are operating on or near patient.
When using the AeroNOx 2.0 adjacent to or stacked with other equipment, observe the operation of
the AeroNOx 2.0 and the other equipment to ensure normal operation.
Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm to any part of the AeroNOx 2.0 and associated
cables. Otherwise, degradation of the performance of this equipment could occur.
Do not use the AeroNOx 2.0 with helium/oxygen mixtures. The AeroNOx 2.0 is only intended to
deliver NO in conjunction with oxygen/air mixtures.
Anytime a new NO gas cylinder and regulator is used, the user must purge to prevent inadvertent
delivery of NO2 to the patient.
If the AeroNOx 2.0 is not going to be used within 10 minutes, depressurize the regulator supply line.
If the AeroNOx 2.0 is pressurized and not used within 10 minutes, repeat the purge procedure.
If the AeroNOx 2.0 is not depressurized and not used within 12 hours, repeat the pre-use procedure.
A backup NO delivery system must always be available in the event the primary system should fail.
Set AeroNOx 2.0 alarm thresholds for the current patient conditions to monitor any inadvertent
changes in treatment. For alarm information, see Section 4., ALARMS.
Be certain all lines and cables are organized to prevent damage or occlusion.
Use only parts, accessories, transducers, and cables designated by International Biomedical for use
with the AeroNOx 2.0. Cables and accessories other than those supplied by International
Biomedical may result in unacceptable operation of the AeroNOx 2.0 and will void the equipment
warranty.
The AeroNOx 2.0 samples gas at a rate of 220 mL/min; this can affect the sensitivity of flow triggered
synchronized breath of some ventilators. The trigger sensitivity, if equipped, should be checked after
connecting AeroNOx 2.0 to the breathing circuit.
Do not change NO, NO2, or O2 sensors while in use.
Do not attempt to maintain, diagnose, or repair the AeroNOx 2.0 while delivering NO to a patient.
No modification of the AeroNOx 2.0 is allowed.
Improper sensor or battery replacement will result in a non-functional or inaccurate device.
Sample/Delivery accessories are single patient use only. DO NOT re-use.

Persons using the AeroNOx 2.0 should be trained and experienced in the use of this device to
assure effective administration of NO, and to avoid injury to the patient or to others resulting from
inhalation of excess NO, NO2, or other reaction products. Not for use by patients.
Persons using this device who may be particularly sensitive to nitric oxide or nitrogen dioxide, 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 AeroNOx 2.0 does not scavenge the exhaust gas, and that this gas is vented from the
underside of the AeroNOx 2.0, or through the side vent in the event that the bottom port is occluded.
Ambient concentrations of nitric oxide or nitrogen dioxide expected to result from the use of this device
are less than 50 ppb.
Only use International Biomedical approved batteries for AeroNOx 2.0.
Even when the external power supply is not connected, the battery provides a bias charge to the NO,
NO2, and O2 cells to keep sensors in a ready state. The power drawn from biasing the sensors will
deplete a new fully charged battery in approximately one week. Because of this, it is recommended
the external power supply of the AeroNOx 2.0 remain plugged in at all times to maintain battery
charge.
Disconnect the battery or leave charging when not in use for extended periods of time.
Allowing the battery to fully discharge repeatedly will reduce the overall number of cycles in the life of
the battery.
Attempting to run the AeroNOx 2.0 for longer than five hours on battery only could result in an
interruption of nitric oxide therapy.
The specified power supply is defined as part of the ME Equipment. Use only the International
Biomedical approved universal power supply for AeroNOx 2.0.
No other devices are known to cause potential interference with the AeroNOx 2.0. If interference
occurs, discontinue use of the AeroNOx 2.0 and use the INOstat Bagger.
Never turn on the NO delivery gas without first turning on the ventilator or bagger flow. Failure to do
this will result in undiluted gas delivery entering the sampling chamber and exposing the sensors to
levels of NO and /or NO2 which may damage the sensors.
NO2 gas may have collected in the AeroNOx 2.0 delivery or ventilator circuit during setup. Run
ventilator and AeroNOx 2.0 on a test lung 30 seconds prior to patient connection to ensure analyzed
levels of NO2 and NO are appropriate.
Only use the NO Worries Sample line with filter and Nafion tubing when operating the AeroNOx 2.0.
Failure to do so may result in the egress of moisture which can impair function as well as damage
internal components.
NO flow must be continually evaluated during nitric oxide administration to ensure accurate dosing.
NO cannot be administered during the calibration process.
Do not sterilize or disinfect with power connected.
Part No. 715-0086, Rev. A
-7-
Page 11
Allow unit to dry thoroughly before use. Immediate use after exposure to excessive cleaning agents
such as Isopropyl Alcohol can affect sensor performance.
Do not push on LCD display.
The VESA 75 mount is required for mounting during transport.
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.
The flush procedure must be performed each time NO therapy is started. This includes initial therapy
starts, tank changes, and re-starting therapy after NO has been off.
Powering the unit off will shut off the delivery gas flow. Gas flow is terminated when the unit is
powered off, whether intentionally, or during a complete loss of power.
DO NOT exceed 2.00 LPM as displayed on the AeroNOx 2.0 flow display. Displayed values in
excess of 2.00 LPM are not accurate. If the flow on the AeroNOx 2.0 flow meter is set at a value
greater than 2.00 LPM, the delivered flow will be higher than the displayed flow value.
The NO2 sensor may easily be damaged by inadvertent high levels of NO2. Use Nitrogen or air to
flush the system after high levels of NO (> 100 ppm) or NO2 (> 20 ppm) have been introduced to the
sensor.
Setting alarm limits to extreme values can render the alarm system useless.
After storage at the extremes of the allowable temperature range, it is recommended that the AeroNOx
2.0 be given at least an hour at room temperature before use.
NOTES:
The Low Cal does not require calibration gases.
Connections to various ventilators are unique to each manufacturer as well as their corresponding
disposable circuits.
When AeroNOx 2.0 is connected to a ventilator and patient is breathing spontaneously, a slight
change in NO ppm (< 10%) may be noted.
When performing high range calibration, make sure to select the correct calibration gas and confirm
expiration date before using.
Never connect calibration circuit to a pressure source > 50 cm H2O; this could damage the sampling
system.
Protective cover not shown in many images throughout this manual should be used at all times to
provide extra impact resistance if dropped.
AeroNOx 2.0 is shipped with battery uninstalled. Follow installation procedure in Section 7.
Part No. 715-0086, Rev. A
-8-
Page 12
Do not mount or position the AeroNOx 2.0 such that the rear power connection, exhaust ports, or the
NO inlet are blocked.
The recommended storage temperature limits are within operational temperature limits to preserve
sensor life. No specific time to cool or warm from storage temperature extremes is indicated. Before
normal use, a pre-check must be performed to allow sensors to stabilize.
Use the tethered rubber plug to seal the DC input jack from the environment when not in use.

*Calibration requires a calibration regulator. An INOstat Backup Bagger kit is also required in
the event of AeroNOx 2.0 failure during use. If your hospital does not have each of these,
they must be purchased as separate items shown below. The same regulator may be used
for NO and NO2, but a purge procedure must be completed each time it is attached to a new
bottle of gas.

1.13. Purge Procedure
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.
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, hose, 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, hose, 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 hose must also be purged prior to connection to the
AeroNOx 2.0.
1.13.1. Purge Procedures for use with Medical Gas Regulators:
a.
Connect cylinder to a matching CGA 626 nitric oxide or nitrogen dioxide
regulator only.
b.
Connect stainless steel hose to quick disconnect.
c.
Open, then immediately close the cylinder valve pressurizing the hose.
d.
Purge (bleed) all of the gas from the regulator and hose with the purge
pin on the AeroNOx 2.0.
e.
Repeat steps c. and d. four more times for a total of five purge cycles.
f.
Leave the regulator installed until it is time to change to a new cylinder.
g.
Repeat the purge procedure any time a regulator is reattached.
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.

1.18. Theory of Operation
The AeroN
NOx 2.0 NO
N delivery system pro
ovides a co
onstant dosse of NO ga
as into the
inspiratory
y limb of the
e ventilator circuit. The
e AeroNOxx 2.0 utilizzes a bi-logic design to
o
ensure saffe delivery of
o NO to the patient. F
First, a NO delivery logic system precisely
measures flow of NO to the venttilator circuit to mainta
ain an accurate NO levvel. Second
d,
a separate
e gas monittoring syste
em uses NO
O, NO2, and
d O2 sensorrs to continuously
measure and
a display concentrattions. The dual logic a
approach a
allows indep
pendent
delivery off NO and monitoring.
m
The dual lo
ogic also alllows the mo
onitoring syystem to sh
hut
down Aero
oNOx 2.0 delivery if it detects a fault in the
e delivery syystem (See
e Below). The
T
set-up deliivery and monitoring
m
is
s performed
d by a train
ned clinician

2.
NO gas enters
s the back of
o the AeroN
NOx 2.0 tthen throug
gh a safety shut-off vallve
which is open during norm
mal operatio
on.
3.
A delivery line is placed in
n the inspirratory limb o
of the ventilator circuitt, between the
t
outllet and hum
midifier (if ap
pplicable). Based on the ventilattor flow, NO
O gas
con
ncentration, and desire
ed dose, the
e operator a
adjusts NO
O flow to rea
