Development History
How Does a Medical Oxygen Concentrator Work?
Medical oxygen is a life-sustaining therapeutic agent required by millions of patients globally suffering from chronic obstructive pulmonary disease (COPD), severe asthma, and acute respiratory distress. Unlike high-pressure cryogenic oxygen cylinders or liquid oxygen systems that require constant, dangerous logistical refills, a medical oxygen concentrator extracts infinite medical-grade gas directly from the ambient air around us. By isolating atmospheric gas at a molecular level, these devices ensure a continuous, reliable source of therapeutic oxygen. To answer how oxygen concentrator works, one must delve into the mechanical separation of air molecules rather than chemical reactions.
