What is a medical oxygen concentrator?

　　Definition of medical oxygen concentrator: medical oxygen concentrator is a medical device used to deliver oxygen to people with respiratory-related diseases. People whose blood oxygen concentration is lower than normal usually need medical oxygen concentrators instead of oxygen.

　　Generally, you cannot buy an oxygen concentrator over the counter. Doctors must prescribe after they have completed a thorough medical evaluation. Doctors usually also show patients how to effectively use these medical oxygen concentrators on the go and at home.

　　The medical oxygen concentrator filters the surrounding air, compresses it to the required density, and then delivers the purified medical grade oxygen to the pulsed dose delivery system or continuous flow system to the patient.

　　It is also equipped with special filters and sieve beds to help remove nitrogen from the air to ensure that patients are provided with completely pure oxygen. These devices are also equipped with an electronic user interface, so you can adjust the oxygen concentration level and delivery settings. Then you inhale oxygen through a nasal cannula or a special mask.

　　You usually measure the output of the medical oxygen concentrator in LPM (liters per minute). Your doctor will determine the level of oxygen you need, which may vary during rest, sleep, and exercise.
