Oxygen Therapy

Oxygen therapy is a treatment that provides you with supplemental, or extra, oxygen. It can help you feel better and stay active.

Oxygen is a gas that is vital to human life. It is one of the gases that is found in the air we breathe. If you have a chronic lung disease, you may need additional (supplemental) oxygen for your organs to function normally.

Here are some conditions that may require supplemental oxygen, either temporarily or long-term:

Although oxygen therapy may be common in the hospital, it can also be used at home. There are several devices used to deliver oxygen at home. Your healthcare provider will help you choose the equipment that works best for you. Oxygen is usually delivered through nasal prongs (an oxygen cannula) or a face mask. Oxygen equipment can attach to other medical equipment such as CPAP machines and ventilators.

If you are on Medicare and have had issues getting your oxygen covered by insurance or getting the amount of oxygen you need, we want to know. Send an email with your story to [email protected]. Your email will be forwarded to the Centers for Medicare and Medicaid Services. Thanks for helping us advocate for lung disease patients who need oxygen.

Warning about over the counter (OTC) portable oxygen concentrators: You may have seen online advertisements for non-prescription, portable oxygen concentrators (POCs). While these are often more affordable, if you have a lung disease like COPD or pulmonary fibrosis, which requires you to use prescription oxygen, these OTC devices may not meet your oxygen needs and it would be important to speak with your health provider before purchasing.

Learn more about portable oxygen concentrators at Lung.org or contact the Lung HelpLine at 1-800-LUNGUSA (1-800-586-4872 and press 2) or submit a question.
