how to clean an oxygen concentrator

Tens of millions of Americans suffer from lung disease, typically caused by smoking, infections, and genetics. That’s why many older adults need home oxygen therapy to help their breathing. O2Assist shares tips on how to properly clean and maintain an oxygen concentrator, the key component in oxygen therapy.

Many people with chronic lung disease (like chronic obstructive pulmonary disease, aka COPD) may be candidates for supplemental oxygen therapy. A prescription for home oxygen has many benefits, like better mood, sleep, quality of life, and prolonged survival.

The centerpiece of home oxygen therapy is the stationary oxygen concentrator. Oxygen concentrators draw in air, compress it, and isolate oxygen for delivery through a nasal cannula, the tube placed over the nostrils. An oxygen concentrator is able to producing a never-ending supply of purified oxygen (90–95%) to meet the needs of individuals with chronic lung disease.

Even though most oxygen concentrators are sturdy, they still need to be cared for correctly. Regular cleaning and maintenance will go a long way to getting the best performance and prolonging its life. After all, an oxygen concentrator is an expensive investment in medical equipment.
