The best maintenance schedule is the one supplied for your exact concentrator and its accessories. Different machines use different filters, cleaning methods and service intervals. A calendar copied from another model can lead to unnecessary replacement or damage.
At handover, ask the supplier to mark which tasks the user may perform and which belong to a trained technician. Keep the manual with the model, serial number, purchase record and service contact. If cleaning requires the concentrator to be switched off, arrange the person’s prescribed oxygen supply first.
Make routine checks easy
Look for blocked vents, a trapped or disconnected tube, damaged accessories and an unfamiliar alarm. Keep the surrounding area free of dust and clutter without spraying cleaning products into the machine. Follow the manual’s instructions for cleaning its exterior and disconnecting power safely.
Feeling gas at the end of a cannula does not verify the prescribed flow or oxygen concentration. If delivery seems different, follow the fault instructions and contact the supplier rather than relying on that informal check.
Identify each filter before cleaning it
Some models have a user-accessible washable filter; others use components that must be replaced or serviced. Find the part in the manual. Do not wash a disposable filter, remove an internal filter or run the device without a required filter.
Where washing is permitted, use the specified method and allow the filter to dry fully before refitting it. Ask the supplier whether dusty conditions warrant more frequent inspection for that model. Do not invent a shorter replacement interval or fit an unverified substitute simply because it looks similar.
Follow accessory instructions separately
Cannulas, masks, tubing and humidifier bottles may have their own instructions and replacement requirements. Inspect them for damage, contamination, stiffness or poor fit and ask about replacements when needed. Single-use accessories must not be treated as indefinitely reusable.
Use a humidifier only as directed by the treating team and equipment instructions. Follow the specified water type, fill limit and cleaning method. Do not add medication, fragrance or a homemade disinfectant mixture. Keep water away from the concentrator and ask for help if liquid enters the unit.
Record what is due
A short maintenance record is more useful than a complicated chart: list the part, the instruction you are following, the last completed date and the next due date or operating-hour interval. Add the supplier’s service visits, reported faults and any parts replaced.
Ask what a scheduled service includes and whether output concentration and flow are checked against the manufacturer’s specification. A warning indicator is not a substitute for the prescribed maintenance programme, and a normal-looking cabinet does not establish internal performance.
