What is Oxygen Concentrator Preventative Maintenance?
Oxygen concentrator preventative maintenance (PM) is routine servicing performed to keep an oxygen concentrator working safely, reliably, and at the correct oxygen output.
It typically includes:
- Inspecting the unit for damage, wear, or abnormal operation
- Checking oxygen concentration and flow rate
- Cleaning or replacing filters as needed
- Inspecting tubing, power cords, and connections
- Checking alarms and safety features
- Performing manufacturer-recommended servicing or component replacement
- Documenting the maintenance for equipment records
Preventative maintenance helps catch problems before the concentrator fails, reducing equipment downtime and helping ensure patients receive the prescribed oxygen therapy.
