What is an Oxygen Concentrator?

Posted on 13th , March 2012


Oxygen concentrator is a medical device which is used to deliver oxygen to patients. The delivered oxygen has substantially higher concentration than available in the room air we breathe. For example room air is made up of around 78% nitrogen, 21% oxygen, 0.93% Argon, 0.033% Carbon Dioxide and some other gases. The Oxygen concentrator helps in removing the nitrogen, leaving the remaining air to be mostly Oxygen. Thus the oxygen delivered is almost pure and is delivered to a patient through his nose via tight fitting face masks or nasal cannula.



Oxygen concentrators are used to give oxygen therapy to patients. This therapy is required when a patient is in chronic or acute condition (like chronic obstructive pulmonary disease, major haemorrhage, trauma, anaphylaxis etc) or when he suffers from an ailment like heart problem, cancer etc. All these conditions prevent the proper level of oxygen from circulating in the blood. Thus high amount of oxygen in the patient's blood is required. The oxygen concentrator increases the percentage of oxygen in the breathing air and thus increases the amount of oxygen delivered in the blood. The device use to measure the amount of oxygen in the blood is known as Pulse Oximeter. Lightweight, easy to read pulse oximeters are the best.
