**Home Oxygen Concentrator: Low Oxygen Alarm Troubleshooting**

Immediately check your power connection, ensure all tubing is unkinked, and try restarting your concentrator; this often clears temporary low oxygen alarms.

* **Check All Tubing for Kinks or Blockages:**
* Examine your nasal cannula/mask tubing for any bends, twists, or blockages.
* Check the main oxygen tubing from the concentrator to your cannula/mask.
* If using a humidifier bottle, ensure it’s not overfilled and the tubing connections are secure and clear.
* **Verify Air Filter Cleanliness:**
* Locate and inspect the main air intake filter (usually on the back or side). If it’s visibly dirty or clogged, clean it according to your owner’s manual (usually with warm soapy water and air dry, or replace). A clogged filter restricts airflow and can trigger the alarm.
* **Ensure Proper Ventilation:**
* Make sure the concentrator is placed on a hard, flat surface at least 6-12 inches away from walls, furniture, or curtains. Blocked air vents can lead to overheating and affect oxygen purity, triggering the alarm.
* **Confirm Flow Setting:**
* Double-check that your concentrator’s flow setting (LPM) matches your prescribed oxygen therapy. Incorrect settings can sometimes contribute to purity issues.
* **Listen for Unusual Noises:**
* Pay attention to any new or unusual sounds coming from the machine, such as grinding, sputtering, or excessive loudness, which could indicate an internal component issue.
* **If Alarm Persists (Critical Step):**
* **Immediately switch to your backup oxygen supply (if available) or seek medical attention.** Do not rely on a concentrator alarming “low oxygen.”
* Contact your oxygen provider or the concentrator manufacturer for professional service and diagnosis. The alarm could indicate a failing sieve bed, compressor, or sensor.
