How Does an Oxygen Concentrator Work?
Think of an oxygen concentrator as a window air conditioner — it takes air in, changes it and delivers it in a different form. The oxygen concentrator takes air in and purifies it for use by individuals who require medical oxygen because of low levels of oxygen in their blood.
It works by:
- Compressing air as the cooling mechanism keeps the concentrator from becoming overheated
- Taking air in from its surroundings
- Using an electronic interface to adjust delivery settings
- Removing nitrogen from the air through sieve beds and a filter
- Delivering purified oxygen through a mask or nasal cannula
Patients who required oxygen therapy in the past mainly relied on pressurized oxygen tanks. Even though these tanks are extremely effective, they’re also fairly inefficient with the suppliers having to visit the patients regularly to replenish their oxygen supply in their tank.
