Common "Oxygen Concentrator" queries answered by top doctors | iCliniq

Oxygen Concentrator

The device called oxygen concentrator helps those suffering from poor intake of oxygen while breathing. People who are affected by asthma, chronic obstructive pulmonary disease, or lung cancer may not be able to breathe in an adequate amount of oxygen with their lungs. With an oxygen concentrator, they can breathe better. The device filters out the nitrogen from the air which doubles the oxygen concentration and supplies it via a tube placed under the nares, so that good oxygen availability is ensured.
