Typically, A doctor prescribe the oxygen concentrator after a comprehensive medical examination od the patient. Doctor will prescribe the oxygen flow (in litre / minutes) that a patient need to inhale to maintain the oxygen saturation in the blood. Most of the time the doctors will also teach the patients how to use these concentrators safely while travelling and at home.
The oxygen concentrators collect the air from surrounding, compress it as required & then pass it through a sieve bed zeolite, Zeolite absorb the nitrogen and pass the oxygen and then deliver filtered oxygen to the patient in a through a flowmeter delivery system with continuous flow.
1. Takes air from the surroundings and filter it.
2. Compresses the air inside the machine.
3. zeolite absorb nitrogen from the air and pass the oxygen.
4. Regulates the Oxygen Delivery through Flowmeter
5. Delivers the purified Oxygen using nasal Cannula.
Oxygen concentrator output is measured in the LPM (litres per minute) like 3 litres per minute.
Your doctor will prescribe the amount of oxygen you need, which may vary during rest, sleep, and while you're exercising.
Pro Tip : 5 Litres is the Flow of the Oxygen per minute . It is not the size of the Oxygen Concetrator Tank .
