Why is hyperbaric oxygen therapy important?
Hyperbaric oxygen therapy involves breathing in oxygen at a high pressure to help fight infection and induce wound healing. The pressurization and oxygen hoods are the most important aspects of the therapy. The hoods increase the oxygen that your lungs take in, and the pressurization increases the amount of oxygen your blood absorbs.
How does hooding affect oxygen?
The hoods increase the oxygen that your lungs take in, and the pressurization increases the amount of oxygen your blood absorbs. This delivers more oxygen to parts of the body where it may be in short supply.

Why It's Done
- 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 increases the amount of oxygen your blood can carry. With repeated scheduled treatments, the temporary extra high oxygen levels encourage normal tissue oxygen levels, even after the therapy is completed. Hyperbaric oxygen t…
Risks
- Hyperbaric oxygen therapy is generally a safe procedure. Complications are rare. But this treatment does carry some risk. Potential risks include: 1. Middle ear injuries, including leaking fluid and eardrum rupture, due to changes in air pressure 2. Temporary nearsightedness (myopia) caused by temporary eye lens changes 3. Lung collapse caused by air pressure changes (barotr…

For your safety, items such as lighters or battery-powered devices that generate heat are not allowed into the hyperbaric chamber. In addition, you may need to remove hair and skin care products that are petroleum based, as they are a potential fire hazard. Your he…
What You Can Expect
- During hyperbaric oxygen therapy
Hyperbaric oxygen therapy typically is performed as an outpatient procedure but can also be provided while you are hospitalized. In general, there are two types of hyperbaric oxygen chambers: 1. A unit designed for 1 person.In an individual (monoplace) unit, you lie down on a ta… - After hyperbaric oxygen therapy
Your therapy team assesses you including looking in your ears and taking your blood pressure and pulse. If you have diabetes, your blood glucose is checked. Once the team decides you are ready, you can get dressed and leave. You may feel somewhat tired or hungry following your tre…
