1. Oxygen Concentrators

• Oxygen Concentrator is a medical device. It filters oxygen from the atmosphere and helps individuals inhale it through a mask or cannula.

• Atmospheric air has about 78% nitrogen and 21% oxygen with other gases making up the remaining 1%.

How does it work?

• The concentrator takes in this atmospheric air, filters it through a sieve. Further, it releases the nitrogen back into the air and works on the remaining oxygen.

• This oxygen compressed and dispensed through a cannula, is 90-95% pure.

• A pressure valve in concentrators helps regulate supply, ranging from 1-10 liters of oxygen per minute.

• Oxygen concentrators are the easiest alternatives to cylinders but can only supply 5-10 liters of oxygen per minute (critical patients may need 40-50 liters per minute).
