Oxygen therapy helps you get more oxygen into your lungs and bloodstream. You may use it if you have a disease that makes it hard to breathe, such as COPD, pulmonary fibrosis (scarring of the lungs), or heart failure. Oxygen therapy can make it easier for you to breathe and can reduce your heart's workload.
Some people need extra oxygen all the time. Others need it from time to time throughout the day or overnight. A doctor will prescribe how much oxygen you need and how often to use it.
To breathe the oxygen, most people use a nasal cannula (say "KAN-yuh-luh"). This is a thin tube with two prongs that fit just inside your nose. People who need a lot of oxygen may need to use a mask that fits over the nose and mouth.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
