An oxygen concentrator is a medical device that concentrates oxygen from ambient air. Atmospheric air has about 78 per cent nitrogen and 21 per cent oxygen, with other gases making up the remaining 1 per cent.
It’s only a little bigger than a computer monitor, yet as cases surge and with oxygen cylinders in short supply across several states, the concentrator is among the most sought after devices for oxygen therapy, especially among patients in home isolation and for hospitals running out of oxygen.
How does it work?
An oxygen concentrator is a medical device that concentrates oxygen from ambient air. Atmospheric air has about 78 per cent nitrogen and 21 per cent oxygen,
with other gases making up the remaining 1 per cent.The oxygen concentrator takes in this air, filters it through a sieve, releases the nitrogen back into the air, and works on the remaining oxygen.
This oxygen, compressed and dispensed through a cannula, is 90-95 per cent pure. A pressure valve in concentrators helps regulate supply, ranging from 1-10 litres per minute.
