How does work Oxygen Concentrator?

An oxygen concentrator is a medical device that concentrates oxygen from ambient air. Atmospheric air has about 78 percent nitrogen and 21 percent oxygen, with other gases making up the remaining 1 percent. The oxygen concentrator takes during this air, filters it through a sieve, releases the nitrogen back to the air, and works on the remaining oxygen.

This oxygen, compressed and dispensed through a cannula, is 90-95 percent pure. A pressure valve in concentrators helps regulate supply, starting from 1-10 liters per minute.

According to a 2015 report by the WHO, concentrators are designed for continuous operation and might produce oxygen 24 hours each day, 7 days per week, for up to five years or more.

At 90-95 percent purity, is that the oxygen from concentrators pure enough?

While it’s not as pure as LMO (99%), experts say it’s ok for mild and moderate Covid-19 patients with oxygen saturation levels of 85% or above. It is, however, not advisable for ICU patients.

Concentrators are attached with multiple tubes to serve two patients at a similar time, but experts don’t recommend it since it carries the danger of cross-infection.

How are concentrators different from oxygen cylinders and LMO?

Oxygen concentrators are the best alternatives to cylinders but can only supply 5-10 liters of oxygen per minute (critical patients might have 40-50 liters per minute) and are best fitted to moderately ill patients.

Concentrators are portable and in contrast to LMO that must be stored and transported in cryogenic tankers, need no special temperature. and in contrast to cylinders that need refilling, concentrators only need a power source to attract ambient air.
