Medical Oxygen Concentrators: Enhancing Respiratory Health with Innovation
Medical oxygen concentrators have become an indispensable tool in modern healthcare, providing a reliable and efficient way to deliver supplemental oxygen to patients with respiratory conditions. These devices work by extracting oxygen from ambient air, concentrating it, and delivering it to patients through a nasal cannula or mask. Unlike traditional oxygen tanks, concentrators do not require frequent refilling, offering a continuous supply of oxygen that enhances patient mobility and convenience.
The core mechanism of a medical oxygen concentrator relies on a process called pressure swing adsorption (PSA). Ambient air, which contains roughly 21% oxygen, is passed through a molecular sieve made of zeolite. This sieve selectively traps nitrogen, allowing oxygen to pass through at higher concentrations, typically around 90–95%. The concentrated oxygen is then delivered to the patient at a controlled flow rate. This process ensures that patients receive a stable and…
