Types of oxygen concentrators
There are two types of oxygen concentrators: home and portable. As the name suggests, the home devices use the electricity supply available from the patient's home. It simply plugs into a wall socket.
How do oxygen concentrators work?
An oxygen concentrator works very much like an air conditioning unit. Air goes in, is modified, and delivered back in the new form.
Oxygen concentrators produce medical grade oxygen on their own. Their process for doing so works in this manner:
They pull in the surrounding room air and filter it.
The oxygen then undergoes a filtration process, and is compressed.
From there, the flow moves through two or more chambers that are filled with a material that removes the nitrogen from the air via a filter and sieve beds.
The medical grade oxygen is then sent through a flowmeter through a nasal cannula or a mask.
