Hyperbaric oxygen therapy

Hyperbaric oxygen therapy uses a special pressure chamber to increase the amount of oxygen in the blood.

Information

Some hospitals have a hyperbaric chamber. Smaller units may be available in outpatient centers.

The air pressure inside a hyperbaric oxygen chamber is about two and a half times higher than the normal pressure in the atmosphere. This helps your blood carry more oxygen to organs and tissues in your body.

The other benefits of increased pressure of oxygen in the tissues may include:

Hyperbaric therapy can help wounds, particularly infected wounds, heal more quickly. The therapy may be used to treat:

This treatment may also be used to provide enough oxygen to the lung during a procedure called whole lung lavage, which is used to clean an entire lung in people with certain medical conditions, like pulmonary alveolar proteinosis.

Treatment for long-term (chronic) conditions may be repeated over days or weeks. A treatment session for more acute conditions such as decompression sickness may last longer, but may not need to be repeated.

You might feel pressure in your ears while you are in the hyperbaric chamber. Your ears may pop when you get out of the chamber.
