Understanding Small Oxygen Concentrators: How Do They Work?

Small oxygen concentrators are medical devices that help people with breathing problems receive concentrated oxygen. Unlike traditional oxygen tanks, which need to be refilled over time, oxygen concentrators draw in the air from the surrounding environment and filter it to isolate the oxygen molecules, producing pure oxygen for inhalation.

The Basics of How Small Oxygen Concentrators Work

Small oxygen concentrators work by taking in ambient air through a series of inlets and compressing it. Then, the air is sent through a series of filters and cylinders, which separate the nitrogen from the oxygen molecules. This leaves a highly concentrated stream of oxygen that is delivered to the user through a nasal cannula or mask.

How to Use a Small Oxygen Concentrator

Using a small oxygen concentrator is relatively simple. Most models come with a user manual that explains the process in detail. To use a small oxygen concentrator, first, make sure it is plugged into an electrical outlet or has a fully charged battery.
