What does it mean when the oxygen concentrator beeps?

Time:2021-06-21 15:30

What should you do when your patient's oxygen machine keeps beeping?  Invacare oxygen concentrators have a loud alarm, which is a safety feature.  The Invacare oxygen concentrator will beep in any of the following situations

Loss of power

User error

The system is not producing enough oxygen

Insufficient oxygen flow

The unit is overheating

There are red, green and yellow LEDs on the front panel of the concentrator that will help you distinguish between possible problems.
The following situations will help you identify possible problems.

1) The alarm goes off but the light does not come on.

This is a power loss. Try unplugging and reinserting the device. If this does not work, make sure the circuit breaker switch on the front of the machine is not tripped. If this does not work, plug something else into the oxygen generator's outlet and see if the outlet has power.
If none of the above suggestions solve the problem, the power cord may be broken, the switch may be bad, or some wiring may be loose, please call your service person.

2) The alarm goes off and the red light comes on.

This could also be a power supply problem, so try the first suggestion. If these problems remain unresolved, your cabinet filter may be clogged and your unit is overheating. Remove and clean the cabinet filter on the side of the oxygen concentrator. You may then need to wait a few minutes until the Invacare oxygen concentrator has cooled down before you can restart it.

3) Alarm goes off and green light comes on

This is caused by insufficient oxygen flow. Check to make sure the flow meter is set high enough (it must be higher than 0.5 l/min). Another common problem is that something is blocking your tubing or the tubing is kinked. Make sure the pipe is not kinked, there are no obstructions, and that the pipe is clear and free of debris.

4) Yellow or red light is on.

Check everything in the first 3 steps first. If the alarm still does not clear successfully, there may be insufficient oxygen purity or a leak inside the concentrator.
The concentrator must produce an oxygen level of more than 92%. This can be measured with an oxygen sensor. If the concentrator is producing less than 92% oxygen, the sieve bed may need to be replaced. Call your local medical equipment repair company for service, otherwise it is time to purchase a new oxygen concentrator.

5) The green and yellow lights are flashing.

This means there is a problem inside the machine and only service personnel can help you.
