OXYGEN

You can connect up to 60 L/min of supplementary oxygen from a
o
O
regulated supply to the AIRVO 2. The AIRVO 2 contains an oxygen

analyzer to help you determine the oxygen fraction you are delivering

to the patient. Your unit may have been initially set up with tighter

limits.
Use continuous oxygen monitoring on patients who would desaturate

significantly in the event of disruption to their oxygen supply.
WARNINGS
Before using the AIRVO 2 with oxygen, read all of the following warnings:
• The use of oxygen requires that special care be taken to reduce the risk of fire.
Accordingly, for safety it is necessary that all sources of ignition (e.g.
electrocautery or electrosurgery) be kept away from the unit and preferably out
of the room in which it is being used. Oxygen should not be used while smoking
or in the presence of an open flame. The unit should be located in a position
where ventilation around the unit is not restricted.
• A spontaneous and violent ignition may occur if oil, grease or greasy
substances come in contact with oxygen under pressure. These substances
must be kept away from all oxygen equipment.
• Ensure that the AIRVO 2 is switched on before connecting oxygen.
• Oxygen must only be added through the special oxygen inlet port on the back
of the unit. To ensure that oxygen enters the unit correctly, the oxygen inlet port
must be fitted properly to the filter holder and the filter holder must be fitted
properly to the unit. The power cord connector should also be well secured.
• Do not connect supplementary oxygen to the AIRVO 2 at flow rates higher
than the AIRVO 2 target flow rate, as excess oxygen will be vented into the
surroundings, or 60 L/min.
• The oxygen concentration delivered to the patient can be affected by changes
to the flow setting, oxygen setting, patient interface or if the airpath is
obstructed.
• When finished, turn off the oxygen source. Remove the output of the oxygen
source from the oxygen inlet port on the back of the unit. The oxygen flow must
be turned off when the unit is not operating, so that oxygen does not build up
inside the device.
• The oxygen analyzer within the AIRVO 2 uses ultrasonic measurement
technology. It does not require in-field calibration. It is designed for use with
pure oxygen - connecting any other gases or mixtures of gases will cause it to
function incorrectly.
CONNECT OXYGEN
Connect the output from the oxygen source to the oxygen inlet port on
the side of the unit. Make sure you push the oxygen tube firmly onto
this connection port.
ADJUST OXYGEN
Adjust the level of oxygen from the oxygen source, until the desired
oxygen fraction is displayed onscreen. It may take the reading several
minutes to settle. You can set the oxygen fraction between the
maximum and minimum values displayed above and below the arrow.
Real-time O
However, note that oxygen fractions below 25% and above 95% will be
displayed as 21% and 100% respectively.
If the oxygen fraction exceeds 95%, the oxygen reading will pulse red
and the device will beep.
WARNINGS
• Note that if the patient's peak inspiratory demand exceeds the flow delivered
by the unit, the fraction of oxygen inspired by the patient will be lower than the
value shown onscreen, due to the additional entrainment of ambient air.
• Check that suitable blood saturation levels are achieved at the prescribed flow.
