Oxygen Concentrator – how does it work ?We know that atmospheric air has roughly 78% nitrogen and 21% oxygen.
Oxygen concentrators are simple devices which do precisely what its name promises – they take in ambient air and increase the oxygen concentration, by filtering out and throwing away nitrogen.These Oxygen concentrators work the same way in supplying oxygen needed by the body such as oxygen tanks or cylinders, with the use of a cannula, oxygen masks or nasal tubes.
