What is Oxygen Concentartor An oxygen concentrator is a medical device that delivers concentrated oxygen to patients who have low blood oxygen levels. It’s a safer, more economical alternative to oxygen tanks because it extracts oxygen directly from the surrounding air instead of storing it. These devices are used in hospitals, clinics, and even in-home care settings..

[Audio] How Does an Oxygen Concentrator Work? So, how does it work? The concentrator takes in air from the room, which is about 21% oxygen and 78% nitrogen. The key process behind this device is Pressure Swing Adsorption (P-S-A--). Inside the concentrator, the air is compressed, and a material called zeolite absorbs the nitrogen, leaving behind concentrated oxygen—usually around 90-95%. This oxygen is then delivered to the patient via a nasal cannula or mask..

So, how does it work? The concentrator takes in air from the room, which is about 21% oxygen and 78% nitrogen. The key process behind this device is Pressure Swing Adsorption (PSA). Inside the concentrator, the air is compressed, and a material called zeolite absorbs the nitrogen, leaving behind concentrated oxygen—usually around 90-95%. This oxygen is then delivered to the patient via a nasal cannula or mask.

[Audio] Principle of Operation: Pressure Swing Adsorption "The core of this device is the Pressure Swing Adsorption (P-S-A--) principle. In P-S-A--, compressed air passes through two chambers filled with zeolite. One chamber adsorbs nitrogen, while the other regenerates the zeolite by releasing the captured nitrogen back into the air. This alternating process ensures a continuous supply of concentrated oxygen to the patient.".
