How Does an Oxygen Concentrator Work?
Oxygen concentrators are medical devices that assist people who
have a low level of oxygen in their blood. They are powered by
plugging the device into an electrical outlet or by using a battery. If a
battery is used, then it will need to be charged by plugging it into an
The oxygen concentrator uses a compressor to pull in air from the
room, moves it through a filter to purify it, then pushes the air into
molecular sieve beds to remove most of the nitrogen. It then
distributes the 90 to 95 percent oxygen and 5 to 10 percent nitrogen
out of the machine to the patient in a controlled manner by adjusting
the knob on a flow meter.
The 5 Step Concentrator Process:
1. Takes air from the room.
2. Compresses the oxygen.
3. Takes out nitrogen from the air.
4. Adjusts the way the air is delivered.
5. Delivers the purified air.
