oxygen concentrator
Medical device that extracts and concentrates oxygen from ambient air for therapeutic delivery.
Full Definition
An oxygen concentrator is a medical device that removes nitrogen from ambient air to provide concentrated oxygen for therapeutic use. Using pressure swing adsorption or membrane separation technology, these devices can deliver oxygen concentrations typically ranging from 87% to 95%. Oxygen concentrators are commonly used for long-term oxygen therapy in home settings, eliminating the need for oxygen tanks or frequent deliveries. They operate continuously, are relatively quiet, and provide a cost-effective solution for patients requiring supplemental oxygen. Modern units often include features like oxygen purity monitoring, flow rate adjustment, and alarm systems.
Usage
Usage note: Hyphenate when used as an adjective (oxygen-concentrator maintenance).
