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

electrical outlet.

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.
