(oxygen therapy) Treatment in which a storage tank of oxygen or a machine called a compressor is used to give oxygen to people with breathing problems. It may be given through a nose tube, a mask, or a tent. The extra oxygen is breathed in along with normal air.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021

(oxygen therapy) Oxygen is a gas that your body needs to work properly. Your cells need oxygen to make energy. Your lungs absorb oxygen from the air you breathe. The oxygen enters your blood from your lungs and travels to your organs and body tissues. Certain medical conditions can cause your blood oxygen levels to be too low. Low blood oxygen may make you feel short of breath, tired, and confused. It can also damage your body. Oxygen therapy can help you get more oxygen. Oxygen therapy is a treatment that provides you with extra oxygen to breathe in. It is also called supplemental oxygen. It is only available through a prescription from your health care provider. 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. There are portable versions of the tanks and oxygen concentrators. They can make it easier for you to move around while using your therapy. You may need oxygen therapy if you have a condition that causes low blood oxygen, such as: COPD (chronic obstructive pulmonary disease); Pneumonia; COVID-19; A severe asthma attack; Late-stage heart failure; Cystic fibrosis; Sleep apnea. Oxygen therapy is generally safe, but it can cause side effects. They include a dry or bloody nose, tiredness, and morning headaches. Oxygen poses a fire risk, so you should never smoke or use flammable materials when using oxygen. If you use oxygen tanks, make sure your tank is secured and stays upright. If it falls and cracks or the top breaks off, the tank can fly like a missile. Hyperbaric oxygen therapy (HBOT) is a different type of oxygen therapy. It involves breathing oxygen in a pressurized chamber or tube. That allows your lungs to gather up to three times more oxygen than you would get by breathing oxygen at normal air pressure. The extra oxygen moves through your blood and to your organs and body tissues. HBOT is used to treat certain serious wounds, burns, injuries, and infections. It also treats air or gas embolisms (bubbles of air in your bloodstream), decompression sickness suffered by divers, and carbon monoxide poisoning. But some treatment centers claim that HBOT can treat almost anything, including Alzheimer's disease, autism, cancer, and Lyme disease. The U.S. Food and Drug Administration (FDA) has not cleared or approved the use of HBOT for these conditions. There are risks to using HBOT, so always check with your provider before you try it.MedlinePlusU.S. National Library of Medicine, 2025

Oxygen is a gas that makes up about 21% of the air we breathe. The lungs take oxygen from the air and transfer it to the bloodstream. Oxygen is needed to burn fuel to release energy, such as in a car engine. Similarly, all living tissue needs oxygen to provide energy for the body. Without enough oxygen, cells function poorly and...Merck & Co., Inc., 2025

Oxygen therapy, in medicine, the administration of oxygen. Oxygen therapy is used for acute conditions, in which tissues such as the brain and heart are at risk of oxygen deprivation, as well as for chronic diseases that are characterized by sustained low blood-oxygen levels (hypoxemia).
