Medical Oxygen Concentrators: A Lifeline for Modern Respiratory Care
Medical oxygen concentrators have become one of the most essential devices in contemporary healthcare, offering a reliable source of oxygen therapy for patients with breathing difficulties. Unlike traditional oxygen cylinders that store compressed gas, concentrators generate oxygen on the spot by filtering the surrounding air. This simple yet powerful mechanism has transformed respiratory care, making therapy more accessible, safer, and easier to manage in both clinical and home environments.
At the core of a medical oxygen concentrator is a technology known as Pressure Swing Adsorption (PSA). Ambient air contains about 78% nitrogen and only around 21% oxygen. The concentrator pulls in the air, removes nitrogen using special filters called molecular sieves, and delivers oxygen-rich output to the patient. This continuous generation of oxygen eliminates the need for frequent refills and reduces dependency on heavy cylinders, especially in remote or resource-limited areas.
