Hyperbaric oxygen remedy involves breathing pure oxygen in a pressurized environment. Hyperbaric oxygen therapy is a well-established remedy for decompression sickness, a potential risk of scuba diving. Other conditions treated with hyperbaric oxygen remedy embody severe infections, bubbles of air in your blood vessels, and wounds that may not heal because of diabetes or radiation injury.
In a hyperbaric oxygen therapy chamber, the air pressure is elevated two to a few times higher than regular air pressure. Under these conditions, your lungs can gather much more oxygen than could be doable breathing pure oxygen at regular air pressure.
When your blood carries this extra oxygen all through your body, this helps fight bacteria and stimulate the discharge of drugs called development factors and stem cells, which promote healing.
Why it’s achieved
Your body’s tissues want an adequate provide of oxygen to function. When tissue is injured, it requires even more oxygen to survive. Hyperbaric oxygen therapy increases the quantity of oxygen your blood can carry. With repeated scheduled remedies, the short-term extra high oxygen levels encourage regular tissue oxygen levels, even after the therapy is completed.
Hyperbaric oxygen therapy is used to deal with a number of medical conditions. And medical institutions use it in different ways. Your physician may counsel hyperbaric oxygen therapy when you’ve got one of the following conditions:

Gangrene
Infection of skin or bone that causes tissue death
Nonhealing wounds, corresponding to a diabetic foot ulcer
Radiation injury
Skin graft or skin flap at risk of tissue demise
Traumatic brain injury
Vision loss, sudden and painless
Risks
Hyperbaric oxygen remedy is mostly a safe procedure. Issues are rare. However this treatment does carry some risk.
Potential risks embody:
Middle ear injuries, together with leaking fluid and eardrum rupture, as a consequence of adjustments in air pressure
Short-term nearsightedness (myopia) caused by short-term eye lens changes
Lung collapse caused by air pressure adjustments (barotrauma)
Seizures as a result of an excessive amount of oxygen (oxygen toxicity) in your central nervous system
Lowered blood sugar in individuals who have diabetes handled with insulin
In certain circumstances, fire — due to the oxygen-rich environment of the remedy chamber
The way you put together
You will be provided with a hospital-approved gown or scrubs to wear instead of regular clothing through the procedure.
To your safety, items comparable to lighters or battery-powered gadgets that generate heat will not be allowed into the hyperbaric chamber. In addition, chances are you’ll need to remove hair and skin care products which can be petroleum based mostly, as they are a potential fire hazard. Your health care workforce will provide instruction on making ready you to undergo hyperbaric oxygen therapy.
During hyperbaric oxygen therapy
Hyperbaric oxygen remedy typically is performed as an outpatient procedure but can also be provided while you might be hospitalized.
On the whole, there are types of hyperbaric oxygen chambers:
A unit designed for 1 person. In an individual (monoplace) unit, you lie down on a table that slides into a clear plastic chamber.
A room designed to accommodate several people. In a multiperson hyperbaric oxygen room — which normally looks like a big hospital room — chances are you’ll sit or lie down. You may obtain oxygen by way of a mask over your face or a lightweight, clear hood placed over your head.
Whether or not you’re in an individual or multiperson environment for hyperbaric oxygen remedy, the benefits are the same.
Throughout therapy, the air pressure in the room is about two to three times the conventional air pressure. The increased air pressure will create a brief feeling of fullness in your ears — just like what you would possibly really feel in an airplane or at a high elevation. You can relieve that feeling by yawning or swallowing.
For many conditions, hyperbaric oxygen remedy lasts approximately hours. Members of your health care workforce will monitor you and the remedy unit all through your treatment.
After hyperbaric oxygen therapy
Your therapy team assesses you including looking in your ears and taking your blood pressure and pulse. When you have diabetes, your blood glucose is checked. Once the workforce decides you are ready, you may get dressed and leave.
You may feel considerably tired or hungry following your treatment. This would not limit normal activities.
Results
To benefit from hyperbaric oxygen remedy, you’ll likely want more than one session. The number of classes depends upon your medical condition. Some conditions, comparable to carbon monoxide poisoning, is perhaps handled in three visits. Others, such as nonhealing wounds, may require forty treatments or more.
