Why Oxygen Concentrators Beep

Oxygen concentrators include built-in safety systems that monitor:

  • Oxygen output
  • Airflow
  • Power supply
  • Internal performance

The Most Common Reasons Your Machine Is Beeping

Low Oxygen Purity Warning

What it means:

The machine is not producing oxygen at the expected concentration.

Possible causes:

  • Dirty or clogged filters
  • Blocked airflow
  • Internal component issue

What to do:

  • Check and clean filters
  • Ensure vents are not blocked
  • Restart the machine

Power Failure Alarm

What it means:

The machine has lost power or is not receiving enough electricity.

Possible causes:

  • Unplugged power cord
  • Power outage
  • Loose connection

What to do:

  • Check power connections
  • Plug into a working outlet
  • Switch to battery (if portable)

Low Battery Alert (Portable Units)

What it means:

Your battery is running low.

What to do:

  • Plug in your device immediately
  • Swap to a charged battery if available

No Breath Detected (Pulse Flow Units)

What it means:

The machine is not detecting your inhale. Though common, this alert can be one of the easiest to fix. It will begin beeping if your oxygen concentrator does not detect sufficient airflow. This may occur with a damaged or kinked tube. To silence this alarm, simply inspect your oxygen tubing for damage or kinks. Replace any damaged tubing and untangle any kinked tubing as that will affect the airflow you are receiving. If the alarm does not resolve itself, check the troubleshooting section of your manual or contact our oxygen specialists.

Possible causes:

  • Cannula not positioned correctly
  • Mouth breathing
  • Shallow breathing

What to do:

  • Adjust your nasal cannula
  • Ensure it is properly placed
  • Try breathing through your nose

High Temperature Warning

What it means:

The unit is overheating.

Possible causes:

  • Blocked vents
  • Poor airflow
  • High room temperature

What to do:

  • Move the unit to a well-ventilated area
  • Keep it away from walls or furniture
  • Turn off and allow it to cool

General System Fault or Error

What it means:

The machine has detected an internal issue.

What to do:

  • Restart the device
  • Check for visible issues
  • Refer to your user manual
