An alarm can indicate a power, connection, airflow or equipment issue. The exact meaning depends on the model, so check the manufacturer instructions and ask the supplier when unsure.
Safe first checks
- Check whether the power cable is connected and the power supply is on
- Check that tubing is not kinked, blocked or disconnected
- Move the equipment away from heat and keep ventilation openings clear
When to seek help
- Contact the supplier if the alarm continues or the cause is unclear
- Do not silence or bypass an alarm without understanding the cause
- Call 999 for sudden or severe breathing difficulty
