Delay Meaning
<2 min The Airvo 3 flow rate is higher than the target flow rate. Check:
• for leaks in the water chamber, heated breathing tube and
patient interface,
• the inlet air filter is inserted correctly, and
• the target flow rate is within the rated range of the interface.
If the issue persists, replace the consumables.
<60 s The Airvo 3 has exceeded an internal temperature limit. Continued operation in
the current configuration may result in a device fault and reduced therapy
Check:
• for blockages in the heated breathing tube, patient interface and inlet air
filter,
• the patient interface is the correct size for the patient,
• the target flow rate is within the rated range of the interface, and
• the ambient temperature is within the rated range of the device.
This alarm will resolve when the internal temperature is within the expected
range.
<30 min The water chamber has run out of water. Replace the water bag to resume
normal operation. Ensure that the water chamber and/or water bag are not
allowed to run out of water to ensure continuous humidification of the breathing
gases.
<30 min The Airvo 3 cannot reach the target humidity. Check the water chamber
contains water and the chamber base is not damaged. Consider reducing the
target humidity or flow rate, if appropriate. If the issue persists, replace the water
chamber.
<1 min The Airvo 3 has detected ambient conditions that are not suitable. Do not use
the Airvo 3 when the ambient temperature is below 18 °C or above 28 °C. Move
the device to a suitable environment.
<5 s There is no oxygen being supplied to the high-pressure (HPO) inlet port during
therapy. Check that the oxygen supply is working. If using an oxygen bottle,
check the bottle is not empty. If switching to the low-pressure (LPO) inlet port or
stopping oxygen delivery, set the FiO
<30 s The oxygen being supplied to the LPO port has fallen below 25% during therapy.
Check if the oxygen supply has been disconnected.
<2 min The oxygen concentration being delivered is lower than the FiO
Check the oxygen supply is properly connected to the HPO inlet port and
there are no leaks at any oxygen hose connections. Make sure the number of
connected devices does not exceed the capacity of the oxygen supply.
Consider using the LPO connection if the oxygen supply has insufficient
capacity.
<2 min The oxygen concentration being delivered is higher than the FiO
Check an oxygen supply is not connected to the low-pressure oxygen inlet port.
Only one oxygen source should be used at a time. Check the oxygen supply is
properly connected to the high-pressure oxygen inlet port and that there are no
leaks at the oxygen hose connections.
<20 s The FiO₂ supplied by the LPO port is above the selected High Oxygen Alarm
threshold for its intended clinical environment (range 30–95% or Off, default:
95%, see Airvo 3 Technical Manual). Check FiO

<15 min Oxygen is being supplied to the Airvo 3 while in standby. Check all oxygen
supplies are turned off and disconnected. If the issue persists, contact your
service representative.
