Oxigen Concentrator What & How about Oxygen Concentrator? An oxygen concentrator is a medical device that concentrates oxygen from ambient air. 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. It uses the surrounding atmosphere to create oxygen -rich air by pulling surrounding air into the oxygen machine , compressing it, purifying it and removing nitrogen and other impurities. The purified, oxygen -rich air is then delivered to the patient. What is the difference between the oxygen Cylinders and Oxygen Concentrators? Oxygen Cylinders have a finite amount of oxygen compressed within them and inhaled by the user until it runs out. Oxygen Concentrators filter and generate medical grade oxygen , at an infinite supply so long as the battery...
