Hyperbaric oxygen therapy includes breathing pure oxygen in a pressurized environment. Hyperbaric oxygen remedy is a well-established treatment for decompression sickness, a possible risk of scuba diving. Other conditions handled with hyperbaric oxygen remedy embrace critical infections, bubbles of air in your blood vessels, and wounds that may not heal as a result of diabetes or radiation injury.

In a hyperbaric oxygen therapy chamber, the air pressure is increased two to 3 occasions higher than regular air pressure. Under these conditions, your lungs can collect much more oxygen than can be potential breathing pure oxygen at regular air pressure.

When your blood carries this extra oxygen throughout your body, this helps combat micro organism and stimulate the release of substances called development factors and stem cells, which promote healing.

Why it’s accomplished

Your body’s tissues need an adequate supply of oxygen to function. When tissue is injured, it requires even more oxygen to survive. Hyperbaric oxygen therapy will increase the quantity of oxygen your blood can carry. With repeated scheduled remedies, the non permanent further high oxygen levels encourage normal tissue oxygen levels, even after the therapy is completed.

Infection of skin or bone that causes tissue dying

Nonhealing wounds, such as a diabetic foot ulcer

Radiation injury

Skin graft or skin flap at risk of tissue demise

Traumatic brain injury

Vision loss, sudden and painless


Hyperbaric oxygen remedy is usually a safe procedure. Problems are rare. However this remedy does carry some risk.

Potential risks embrace:

Center ear injuries, including leaking fluid and eardrum rupture, on account of changes in air pressure

Temporary nearsightedness (myopia) caused by non permanent eye lens adjustments

Lung collapse caused by air pressure changes (barotrauma)

Seizures on account of an excessive amount of oxygen (oxygen poisonousity) in your central nervous system

Lowered blood sugar in people who have diabetes handled with insulin

In certain circumstances, fire — because of the oxygen-rich setting of the therapy chamber

How you put together

You will be provided with a hospital-approved gown or scrubs to wear instead of regular clothing throughout the procedure.

To your safety, items such as lighters or battery-powered units that generate heat are usually not allowed into the hyperbaric chamber. In addition, chances are you’ll must remove hair and skin care products that are petroleum based, as they are a potential fire hazard. Your health care group will provide instruction on preparing you to undergo hyperbaric oxygen therapy.

Throughout hyperbaric oxygen therapy

Typically, there are types of hyperbaric oxygen chambers:

A unit designed for 1 person. In a person (monoplace) unit, you lie down on a table that slides into a clear plastic chamber.

A room designed to accommodate a number of people. In a multiperson hyperbaric oxygen room — which usually looks like a big hospital room — you could sit or lie down. You could receive oxygen through a mask over your face or a lightweight, clear hood placed over your head.

Whether you are in an individual or multiperson surroundings for hyperbaric oxygen remedy, the benefits are the same.

Throughout remedy, the air pressure within the room is about two to 3 occasions the normal air pressure. The increased air pressure will create a brief feeling of fullness in your ears — much like what you may really feel in an airplane or at a high elevation. You’ll be able to relieve that feeling by yawning or swallowing.
