What This Guide Helps With
Addresses concentrator not powering on, shutting down unexpectedly, or failing to operate on battery backup due to external power or connection issues.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- If the concentrator loses power, immediately transition the patient to an alternate oxygen source (backup concentrator or oxygen tank).
- Ensure continuous oxygen delivery is maintained.
2. Verify the Reported Issue
- Attempt to power on the unit.
- Observe for no power, intermittent shutdown, AC-only operation, or battery alarms.
3. Check AC Power Source (Most Common Cause)
- Plug the unit into a known working outlet.
- Test outlet with another device.
- Avoid power strips or extension cords.
4. Inspect Power Cord and Connections
- Ensure cord is fully seated at both ends.
- Inspect for cuts, fraying, or bent prongs.
- Try a known-good power cord if detachable.
5. Check Power Indicator Lights and Display
- Verify power LED and display are active.
- Look for warning or error indicators.
6. Test Battery Backup Function (If Equipped)
- Disconnect AC power.
- Observe if the unit continues running or shuts off.
- Check for battery alarms.
7. Allow Battery to Charge Fully
- Reconnect AC power and allow full charging time.
- Verify charging indicator if present.
8. Inspect External Airflow and Ventilation
- Check intake vents and filters.
- Ensure airflow is not blocked.
- Clean or replace filters if needed.
9. Check for Signs of Internal Power Issues
- Look for burning smell, excessive heat, or unusual noises.
- Note any abnormal behavior during operation.
If the Problem Persists
If all external power sources, cords, and battery conditions have been verified, the issue is likely internal (power supply, battery pack, or control circuitry).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and is part of proper troubleshooting.
Clinical Use Tip
Never troubleshoot a concentrator while it is actively supporting a patient. Always switch the patient to a verified oxygen source before beginning diagnostics.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Oxygen concentrator not powering on and failed to operate during transport."
Cause
What was observed during troubleshooting.
Example:
"Failed internal battery pack not holding charge; AC power verified functional."
Resolution
What action was taken.
Example:
"Removed unit from service and sent for battery replacement and power system evaluation."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord inspected or swapped
- Battery runtime observed
- Indicator lights status
- Any alarms displayed
- Signs of heat, smell, or noise
- Final device status
Final Thought
Power-related issues should always be approached from the outside in. Verify simple causes first, protect patient oxygen delivery, and escalate appropriately when internal failure is suspected. Proper documentation ensures reliability tracking and supports long-term equipment safety.
That is successful troubleshooting.
