What is oxygen concentrator?
An oxygen concentrator is a medical device which is designed to deliver a concentrated flow of oxygen to a patient. The air from an oxygen concentrator has a higher concentration of oxygen than the surrounding ambient air, but the device does not rely on the use of oxygen tanks. There are a number of reasons to use an oxygen concentrator with a patient, and these devices are subject to varying degrees of regulation, depending on where they are being used.

With an oxygen concentrator, the device pulls air into a chamber which absorbs nitrogen. The oxygen-rich air is routed through a tube to the patient, while the nitrogen is vented harmlessly. Depending on the size of the device, it can filter and concentrate varying amounts of air per minute. Oxygen concentrators can be used in place, as seen in hospital rooms, and several companies also make portable versions which can be used by people while they are traveling or wish to be ambulatory.

Using an oxygen concentrator is much safer than using an oxygen tank. The risk of explosion is not present, and the device is easy to operate.
