Philips Everflo Oxygen Concentrator

An oxygen concentrator receives air, purifies it, and then distributes the newly formed air. Before it goes into the concentrator, air is made up of 80 percent nitrogen and 20 percent oxygen. An oxygen concentrator uses that air then it comes out as 90 to 95 percent pure oxygen and 5 to 10 percent nitrogen.EverFlo by Philips Respironics is a stationary oxygen concentrator that delivers all of the features homecare providers and patients could want from a device without the weight, bulk or frequent maintenance associated with other devices.An oxygen concentrator takes regular air and purifies it to 90-95% oxygen. To do this, the concentrator uses a compressor that moves air into sieve bed filters to remove the nitrogen. It then distributes the purified oxygen through hoses inserted into the nostrils. The nitrogen is later released back into the air.
