Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized environment. Hyperbaric oxygen therapy is a well-established treatment for decompression sickness, a potential risk of scuba diving. Different conditions treated with hyperbaric oxygen remedy embrace serious infections, bubbles of air in your blood vessels, and wounds that will not heal because of diabetes or radiation injury.

In a hyperbaric oxygen remedy chamber, the air pressure is increased to three times higher than regular air pressure. Under these conditions, your lungs can gather a lot more oxygen than would be attainable breathing pure oxygen at normal air pressure.

When your blood carries this further oxygen all through your body, this helps struggle micro organism and stimulate the release of substances called growth factors and stem cells, which promote healing.

Why it’s performed

Your body’s tissues want an adequate supply 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 treatments, the momentary further high oxygen levels encourage normal tissue oxygen levels, even after the remedy 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 remedy if in case you have one of the following conditions:

Severe anemia

Brain abscess

Bubbles of air in your blood vessels (arterial gas embolism)

Burns

Carbon monoxide poisoning

Crushing injury

Deafness, sudden

Decompression sickness

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 death

Traumatic brain injury

Vision loss, sudden and painless

Risks

Hyperbaric oxygen therapy is generally a safe procedure. Complications are rare. However this therapy does carry some risk.

Potential risks include:

Middle ear injuries, including leaking fluid and eardrum rupture, as a consequence of changes in air pressure

Momentary nearsightedness (myopia) caused by short-term eye lens modifications

Lung collapse caused by air pressure changes (barotrauma)

Seizures as a result of too much oxygen (oxygen poisonousity) in your central nervous system

Lowered blood sugar in individuals who have diabetes treated with insulin

In sure circumstances, fire — because of the oxygen-rich environment of the therapy chamber

The way you put together

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

For your safety, items such as lighters or battery-powered units that generate heat should not allowed into the hyperbaric chamber. In addition, you may have to remove hair and skin care products that are petroleum based, as they’re a possible fire hazard. Your health care staff will provide instruction on preparing you to undergo hyperbaric oxygen therapy.

Throughout hyperbaric oxygen remedy

Hyperbaric oxygen remedy typically is performed as an outpatient procedure but can also be provided while you are hospitalized.

Basically, there are two 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 transparent plastic chamber.

A room designed to accommodate a number of people. In a multiperson hyperbaric oxygen room — which usually looks like a large hospital room — you may sit or lie down. Chances are you’ll receive oxygen by way of a mask over your face or a lightweight, clear hood positioned over your head.

Whether you’re in a person or multiperson surroundings for hyperbaric oxygen therapy, the benefits are the same.

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

For most conditions, hyperbaric oxygen therapy lasts approximately hours. Members of your health care group will monitor you and the remedy unit all through your treatment.

After hyperbaric oxygen remedy

Your therapy crew assesses you including looking in your ears and taking your blood pressure and pulse. When you’ve got diabetes, your blood glucose is checked. Once the team decides you’re ready, you will get dressed and leave.

You might feel somewhat tired or hungry following your treatment. This would not limit regular activities.

Results

To benefit from hyperbaric oxygen therapy, you’ll likely need more than one session. The number of sessions depends upon your medical condition. Some conditions, corresponding to carbon monoxide poisoning, could be treated in three visits. Others, reminiscent of nonhealing wounds, may require 40 treatments or more.
