Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An oxygen concentrator is a device providing oxygen therapy to a patient at minimally to substantially higher concentrations than available in ambient air. They are used as a safer, less expensive, and more convenient alternative to tanks of compressed oxygen. Common models retail at around US$800. Leasing arrangements may be available through various medical-supply companies and/or insurance agencies. Oxygen concentrators are also used to provide an economical source of oxygen in industrial processes.
