Sanitization - Cleaning Oxygen Concentrators



Cleaning Oxygen Concentrators




Supplemental oxygen is frequently prescribed for patients who have respiratory illnesses. The most cost-effective method of providing additional oxygen is with a machine called an oxygen concentrator. This is a machine that pulls oxygen from room air. It may or may not have a bubbler bottle with the unit. The use of oxygen equipment requires great care in keeping the equipment clean and using it safely.


Only the base unit will be passed on to a new user. Tubing, connectors and cannula (nosepiece) should be removed and discarded.


 The manufacturer’s instructions should be followed for the specific oxygen concentrator. If these are not available, the following general procedures may be used. Careful cleaning is essential to the prevention of respiratory infections.

Tools and supplies            Disposable gloves            Clean towels or disposable towels            Mild dishwashing liquid             Plastic storage bag for bubbler bottle            Pick or tweezers The technician should follow the approved handwashing procedure and wear disposable gloves to clean the unit.

Bubbler bottle. If the unit has a plastic bubbler bottle, it should be removed from the unit and drained of any remaining water. To clean, it should be washed in warm, soapy water with a mild dishwashing liquid, and then rinsed well. For disinfection, it should be soaked in a mixture of one part white distilled vinegar to three parts water for 30 minutes. After soaking, the bottle should be rinsed well and excess water shaken off. The bottle should be allowed to air dry, and then stored in a clean plastic zip bag.


Concentrator unit. The cabinet surface should be wiped with a cloth dampened in water. Neither wax, spray, nor furniture polish should be used. Dirt and debris should be removed from wheels or casters. A vacuum cleaner may help, but sometimes the removal of string or hair may require a pick or tweezers.


Filter. The outside filter should be removed and washed in warm, soapy water, then rinsed well. Excess water should be squeezed gently from the filter and it should be patted dry with a clean towel before replacing in the unit.
