reach target
Check the heated breathing tube or patient interface for blockage.
Check whether the target flow setting is too high for the patient interface
flow
being used (refer to "Setting up AIRVO 2" - "Select Patient Interface").
You will be prompted for acknowledgement.
WARNINGS
• The oxygen concentration delivered to the patient can be affected by
changes to the flow setting. Adjust the level of oxygen from the oxygen
source as necessary.
Check water The chamber has run out of water.
When a chamber runs dry, the chamber float may be damaged. Replace the
chamber and water bag.
To ensure continual humidification, always ensure that the water chamber
and/or water bag are not allowed to run out of water.
Cannot The unit cannot reach the target temperature setting.
reach target
You will be prompted for acknowledgement. The most likely cause for this
is that the unit is operating at a high flow rate in low ambient conditions.

Consider decreasing the target flow setting.
WARNINGS
• The oxygen concentration delivered to the patient can be affected by
changes to the flow setting. Adjust the level of oxygen from the oxygen
source as necessary.
Check
The unit has detected that it is operating in unsuitable ambient conditions.
This alarm may be caused by a sudden change in ambient conditions.
operating
Leave the unit running for 30 minutes. Switch the unit off and then restart.
conditions
[Power out] The unit has been disconnected from the mains/utility power socket.
No visual alarm. The auditory alarm will sound for at least 120 seconds. If
power is reconnected in this time, the unit will automatically restart.
WARNINGS
• Appropriate patient monitoring must be used at all times. Loss of therapy
will occur if power is lost.
ALARM LIMITS
Most alarm limits are pre-programmed. The exceptions are listed below. These alarm limits may be
changed to other values by authorized personnel. Changes will be preserved during or after any power
loss.

WARNINGS
• A hazard can exist if different alarm presets are used on different units within any single area, eg. an intensive care unit.
• Alarm limits set to extreme values can render the alarm system useless.
CHECKING ALARM SYSTEM FUNCTIONALITY
The functionality of the alarm system can be checked at any time when the unit is turned on.
Remove the heated breathing tube. You should see the "Check tube" visual alarm signal and hear the
auditory alarm signal. If either alarm signal is absent, do not use the unit and refer to the AIRVO 2 Technical
Manual for a guide on troubleshooting. If problems persist, contact your Fisher & Paykel Healthcare
representative.
AUDITORY INFORMATION SIGNALS
