An oxygen concentrator is a type of medical device used for delivering
oxygen to individuals with breathing-related disorders. Individuals
whose oxygen concentration in their blood is lower than normal often
require an oxygen concentrator to replace that oxygen.
It`s
also equipped with special filters and sieve beds which help remove
Nitrogen from the air to ensure delivery of completely purified oxygen
to the patient. These devices also come with an electronic user
interface so you can adjust the levels of oxygen concentration and
delivery settings. You then inhale the oxygen through the nasal cannula
or special mask.

Generally,
you can`t buy an oxygen concentrator over the counter. A doctor must
prescribe it after they`ve completed a thorough medical evaluation. The
doctors will also typically show the patients how to effectively use
these concentrators while traveling and in their home.
Oxygen
concentrators filter surrounding air, compressing it to the required
density and then delivering purified medical grade oxygen into a
pulse-dose delivery system or continuous stream system to the patient.
