Oxygen concentrators are life-saving devices for many people with respiratory conditions, providing a continuous flow of oxygen to maintain health and quality of life. However, like any medical equipment, they’re equipped with alarms to ensure safety and proper functioning. These alarms are not just random sounds—they are crucial alerts designed to signal when something needs attention.
As a certified respiratory therapist, I’ve worked extensively with patients and caregivers to troubleshoot these alarms and ensure uninterrupted oxygen therapy. In this article, I’ll explain the most common oxygen concentrator alarms, what they mean, and how to address them effectively.
Why Do Oxygen Concentrators Have Alarms?
Oxygen concentrators have built-in safety mechanisms to alert users of potential issues. These alarms serve as your first line of defense to:
- Ensure the device is delivering oxygen at the prescribed levels.
- Prevent malfunctions that could impact your therapy.
- Prompt immediate action to resolve problems.
Ignoring these alarms can lead to interrupted oxygen supply, which may pose
Common Oxygen Concentrator Alarms and What They Mean
Here’s a breakdown of the most common alarms and how to address them:
1. Low Oxygen Purity Alarm
- What It Means: The concentrator is not delivering oxygen at the required purity level (usually 90-95%).
- Causes:
- Clogged or dirty filters.
- Worn-out sieve beds.
- Operating at high altitudes or in extreme temperatures.
- What to Do:
- Check and clean the filters.
- Restart the machine to reset its oxygen purity monitor.
- If the issue persists, contact your provider for maintenance or replacement of the sieve beds.
2. No Flow or Low Flow Alarm
- What It Means: The concentrator detects insufficient oxygen flow.
- Causes:
- Kinked or blocked tubing.
- Improperly connected tubing or cannula.
- Internal flow issues in the device.
- What to Do:
- Inspect the tubing for kinks, twists, or blockages.
- Ensure the tubing and cannula are securely connected to the device.
- If flow is still insufficient, test the output directly from the concentrator port. Contact your provider if the problem continues.

- What It Means: The concentrator is overheating, which could affect performance or safety.
- Causes:
- Poor ventilation around the device.
- High room temperatures.
- Prolonged use without breaks.
- What to Do:
- Ensure the concentrator has at least 12 inches of space on all sides for proper airflow.
- Move the device to a cooler, well-ventilated area.
- Turn off the device for 15-30 minutes to allow it to cool before restarting.
5. Service Required Alarm
- What It Means: The device has detected an internal issue or is due for maintenance.

- Overdue servicing.
- What to Do:
- Refer to the user manual for troubleshooting specific to your model.
- Contact your supplier or manufacturer to schedule maintenance.
- Switch to a backup oxygen source while awaiting repairs.
6. Blocked Filter Alarm
- What It Means: The intake filter is clogged, restricting airflow.
- Causes:
- Dust, debris, or lack of regular cleaning.
- What to Do:
- Remove and clean the filter with warm water and mild soap. Let it dry completely before reinserting.
- Replace the filter if cleaning doesn’t resolve the issue.
7. System Error Alarm
- What It Means: The concentrator is experiencing an unspecified technical fault.
- Causes:
- Internal software or hardware issues.
- What to Do:
- Turn the device off, wait a few minutes, and restart it.
- If the alarm persists, contact the manufacturer or your provider for technical support.
