Before returning your AIRVO 2, please follow the steps below
Objective: to prevent the unnecessary return of working devices
If this checklist does not solve your issue and your local Service Technician is unable to help, please
complete the following paperwork before returning the unit:
• FM660: Product surveillance report form (ask your local Product Manager if you don’t know what this is)
• FM1076: Event and device questions form (online version available by clicking here)
The unit won’t turn on
1. Is the AIRVO 2 (still) plugged into the mains power?
2. Is the power cord securely inserted into the back of the device?
3. Is the power cord damaged?
• If yes, it needs to be replaced. See Appendix C for a list of spare parts.
• If no, try another power cord.
4. Try plugging the AIRVO 2 into another power outlet.
5. In order to test if the power outlet is working, try plugging a different electrical device into the power outlet
and turning it on.
6. The unit could be ‘on’ but display not working. Check this by starting the unit without a tube and check
that the audible alarm activates.
Power out (screen is black). The auditory alarm will sound for 120 seconds.
• The most likely cause is that the power cord has been dislodged or disconnected.
1. Please follow the instructions (above) for the issue “the unit won’t turn on”
• Remember, you can press the mute button to silence the alarm temporarily.
“Check tube” or error E-38 appears on the AIRVO 2 screen

• Please note: if the “check for blockages” alarm is not attended to, within 2 minutes, it may
become error E-121.
WATER CHAMBER AND LEFT HAND CHAMBER PORT
1. Has the MR290 water chamber become overfilled? It should not fill above the black line of the chamber, as per
the User Manual.
• If yes, it needs to be replaced with a new water chamber, as it is faulty.
2. Have the silicone flaps (of the non-return valve [NRV]), found inside the left-hand chamber port, been
displaced?
• If they have been, return them to the correct position using a non-sharp tool, such as a pair of non-sharp
tweezers.
• Please note: If the NRV is damaged or missing you can order it as a spare part. See Appendix C for details.
HEATED BREATHING TUBE
1. Is the heated breathing tube visibly blocked or kinked?
PATIENT INTERFACE AND MODE
1. Is the patient interface visibly blocked or kinked?
2. Should the unit be in Junior Mode?
• If you are using a junior tube (900PT53x) and cannula (OPT316 - purple cannula or OPT318 - green
cannula) for your patient but the unit is set to default (adult) mode, you will generate a blockage alarm.
• See the User Manual for information regarding patient interfaces.
• See Appendix B for identification of the default and junior tube and chamber kits, via their labels.
3. Are you using an unsuitable cannula?
• The OPT312 (red cannula) and OPT314 (yellow cannula) are not able to be used with the AIRVO 2.
AIR FILTER
1. Is there an object present in the air filter or filter holder?
2. Is the air filter significantly discolored?

AIRVO 2 | Common Issues Checklist
Oxygen “O2 too low” message appears on the AIRVO 2 screen
• The measured oxygen level has fallen below the allowed limit.
1. Allow the device 15 - 30 minutes to warm up, (or longer) if the AIRVO 2 has been stored in a cool room and is
now being used in a significantly warmer room. Cool temperatures can affect the sensor.
2. Is the oxygen source (wall or cylinder flow meter) turned on?
3. Is the oxygen source empty or faulty?
4. Is the “oxygen extension inlet kit” installed correctly, as per the instructions (PN 185047463) and have you
confirmed there are no kinks in the “inlet kit” oxygen tubing?
5. Is the oxygen source tubing correctly and securely connected to the AIRVO 2?
6. Adjust the level of oxygen from the oxygen source as necessary, i.e. have you tried turning the oxygen up
slightly?
Oxygen “O2 too high” message appears on the AIRVO 2 screen
1. Adjust the level of oxygen from the oxygen source as necessary, i.e. have you tried turning the oxygen down
slightly?
The unit “cannot reach the target flow” appears on the AIRVO 2 screen
1. Firstly, please follow the instructions (on a previous page) for the issue “check for blockages”.
2. Is the target flow setting too high for the patient interface being used?
• Please check the swing tag PN 185047452 for the appropriate flow range for each patient interface.
• Please note: If the AIRVO 2 cannot reach the target flow setting, it will choose appropriate new target settings
and prompt the user to acknowledge.
The
unit
“cannot reach the target temperature” appears on the AIRVO 2 screen
user
to acknowledge.
• The most likely cause for this is that the unit is operating at a high flow rate in a low temperature room.
Consider decreasing the target flow setting.
1. Is the AIRVO 2 being used in an environment below 18 °C (64 °F)?
• If yes, then proactive management of condensation may be required. See the issue “Preventing excessive
condensation” on page 6 of this document.
2. Remove chamber and re-insert. This may result in a better connection between heater plate and water chamber,
enabling the device to reach temperature.

AIRVO 2 | Common Issues Checklist
“Check water” message appears on the AIRVO 2 screen
1. Is the water bag empty?
2. Is the water chamber empty?
• If yes, you need to replace the water chamber as it may be damaged.
3. Is there a kink in the fluid line/feed tube, preventing water from flowing into the chamber?
4. Try opening the vent cap to see if this starts the flow.
“Check operating conditions” message appears on the AIRVO 2 screen
•
This alarm may be caused by a sudden change in ambient conditions, e.g. storing the unit in a cold place,
then using it in a warm place.
1. Is the ambient room temperature less than 10 °C (50 °F) or greater than 30 °C (86 °F).
2. Leave the unit running for 30 minutes. Switch the unit off, then restart.

Preventing
excessive condensation
Excessive condensate
accumulates in the heated breathing tube
1. Is the AIRVO 2 being used in a room with ambient conditions between 18 – 28 °C (64 - 82 °F)?
• If the room is less than 18 °C (64 °F), condensation is more likely to occur.
2. Is the AIRVO 2 placed below head height?
• This will allow condensate that forms to drain towards the chamber, away from the
patient.
3. Is there a local source of cooling (which will make excess condensation more likely) acting on the heated
breathing tube, such as:
• A fan being used to cool the patient,
• An air conditioning unit or vent nearby or
• An open window?
• Are you able to remove or minimize these sources of cooling, e.g. redirect the fan (cooling the patient)ed
away
from the heated breathing tube?
Managing excessive condensation
1. Put a system in place to check the tube (perhaps hourly) for condensate.
2. If condensation is present, drain it back into the chamber:
• First, disconnect the patient interface from the heated breathing tube,
• Drain the tube by lifting the patient end of the tube, allowing the condensate to run
into the chamber.
• Please note: At higher target flow settings it may be necessary to first reduce the
target flow setting, to ensure that the condensate drains safely and effectively.
3. If condensate persists, consider turning the target temperature down.
• Turning the target temperature down to 34 °C will decrease the humidity output of the AIRVO 2, which should
lead to less condensation.
• Please keep in mind that both the temperature and humidity level delivered to the patient will also be lower.
An error code, E-xxx, appears on the AIRVO 2 screen
1. If you see an error code make a note of the code, switch the unit off, restart it and wait for 10 minutes. Does
the error reappear?
• If no, carry on using the device.
• If yes, please locate your error number in Appendix A and follow the instructions.
