This is a virtual simulator wich you can train with. Oxygen therapy is a treatment that provides you with extra oxygen to breathe in. You may get it in the hospital, another medical setting, or at home. Some people only need it for a short period of time. Others will need long-term oxygen therapy.
There are different types of devices that can give you oxygen. Some use tanks of liquid or gas oxygen. Others use an oxygen concentrator, which pulls oxygen out of the air. You will get the oxygen through a nose tube (cannula), a mask, or a tent. The extra oxygen is breathed in along with normal air.
