All alarms should be tested before use. Please note the device is ‘silenced’ for the first 1 minute of operation.
High flow / disconnection alarm (to alert in the event of leak or disconnection)
To check
Turn the ventilator on and let the air flow freely from the mask. After 15 seconds the ventilator will display the graphic below with a continuous alarm. This is a pass.
To fix
Push the alarm silence (silence lasts for 2 minutes). Check the mask for unintentional leaks. If there are none, check the tubing from the ventilator to the mask. If either the mask or tubing are damaged, please contact for replacements.
Low flow alarm (to alert in the event of blockage or obstruction)
To check
Turn the ventilator on & occlude the end of the tubing (not the mask). After 15 seconds the ventilator will display the graphic below with a continuous alarm. This is a pass.
To fix
Remove the object blocking the tube. This may be either internal or external. Should you require a new tube please contact for replacements.
Power fail alarm (to alert in the event of mains power failure)
There is an intermittent alarm to notify you if the ventilator begins to run on internal battery, either in the event of a power failure or if the device has been disconnected from the main supply.
Please note that the ventilator should be plugged in to the mains supply at all times.
To Check
Without the patient connected, whilst the ventilator is running, disconnect it from the mains supply. If the graphic below is displayed, and intermittent alarm will sound and the battery LED will flash. This is a pass.
To resolve
Ensure mains power is connected. If the ventilator shuts down when disconnected from the mains, please ensure it has been plugged in for 24 hours. If it continues to shut down despite this, then please contact the team for a replacement.
