Capnography is a special test that helps doctors see how a person is breathing. When we breathe in, we take in oxygen and when we breathe out, we release carbon dioxide. Capnography helps doctors see how much carbon dioxide a person is releasing when they breathe out.
It works like this: The person wears a small device called a capnograph that attaches to their nose or mouth. When the person breathes out, the device measures how much carbon dioxide is in their breath. The results show up on a screen as a graph, like a squiggly line.
Doctors look at the graph to make sure that the person is breathing enough and that their body is getting enough oxygen. If the graph shows that the person is not breathing enough or that there isn't enough oxygen in their body, then the doctors can do things to help them breathe better, like giving them oxygen or a breathing mask.
Capnography is a really helpful tool that doctors use when they want to make sure that a person is breathing properly. It's not scary or painful, and it helps doctors keep people healthy!
