Oxygen concentrator

An oxygen concentrator is a machine that helps people who have trouble breathing to get the oxygen they need. Our bodies need oxygen to live, so it's important to make sure we can breathe enough of it.

The oxygen concentrator takes in air from the room and filters it to remove gases that aren't oxygen, like nitrogen. Nitrogen is a gas that's all around us but our bodies don't need it. By removing it, the oxygen concentrator is able to create a concentration of oxygen in the air that's much higher than what's found in regular air.

This concentrated, pure oxygen is then delivered through a plastic tube to the person's nose or mouth, so they can breathe it in. This is called an oxygen supply or oxygen therapy.

The concentrator is very helpful for people with lung or heart problems that can't get enough oxygen from just breathing in regular air. It allows them to get the amount of oxygen they need to live, move around, and feel better.

When someone needs oxygen therapy, their doctor will prescribe the amount of oxygen they need and how often they need to use their concentrator. It's important to follow these instructions carefully to get the most benefit from the machine.
