The Science Behind Oxygen Concentration

The air we breathe consists of approximately 78% nitrogen, 21% oxygen, and a small percentage of other gases. To provide concentrated oxygen, a portable oxygen concentrator removes the nitrogen and other gases using a filter system.

This filter system consists of zeolite, a material that has a high affinity for nitrogen. Once the air enters the concentrator, it passes through this filter, which adsorbs the nitrogen and allows the oxygen to pass through. The oxygen is then collected and delivered to the user through a delivery system.

Components of a Portable Oxygen Concentrator

A portable oxygen concentrator consists of several essential components that work together to ensure the proper delivery of oxygen. These components include an air inlet, compressor, sieve beds, oxygen reservoir, flow meter, and delivery system.

The air inlet is responsible for drawing in ambient air, which then goes through the compressor to increase its pressure. This compressed air is directed to the sieve beds, which house the zeolite filters. These filters separate the nitrogen from the oxygen, allowing the oxygen to be collected in the oxygen reservoir.

From the reservoir, the oxygen is released at the desired flow rate using the flow meter. Finally, the oxygen is delivered to the user through a nasal cannula or mask, allowing them to breathe in the concentrated oxygen.

Benefits of Using a Portable Oxygen Concentrator
