Hyperbaric Oxygen Therapy (HBOT) is a medical treatment that delivers pure oxygen inside a pressurized chamber. During a session, you breathe oxygen at pressures higher than normal air pressure at sea level, and this raises the amount of oxygen carried through your blood to your tissues. Doctors use HBOT in hospitals and specialized clinics to support healing for various conditions. Here are some things to know about HBOT:
How Does Hyperbaric Oxygen Therapy Work?
HBOT works by increasing the amount of oxygen in your bloodstream, allowing your body to repair and recover more effectively. Patients are placed inside a chamber, and the air pressure rises to two or three times the level you experience daily. This allows the lungs to take in much more oxygen than they would with regular air. That oxygen dissolves into your blood plasma, not just your red blood cells. As a result, oxygen reaches areas where circulation is reduced or blocked.
Tissues need oxygen to repair themselves and fight infection. When blood flow is poor, healing slows down. Hyperbaric oxygen therapy temporarily floods the body with extra oxygen to support these natural processes. Some treatment plans involve a single session, while others require multiple visits over several weeks.
What Does It Treat?
Healthcare providers use HBOT for a defined set of conditions, many of which are approved by medical authorities. These include:
- Serious infections, such as bone and skin infections
- Carbon monoxide poisoning
- Wounds that heal slowly, including some diabetic foot ulcers
- Radiation injuries that affect tissue after cancer treatment
- Skin grafts or flaps at risk of tissue death
- Severe anemia in specific cases
- Sudden hearing loss
Doctors recommend HBOT based on a patient’s diagnosis and overall health. The therapy is often part of a broader treatment plan, and a physician decides whether it fits a particular case. When HBOT is recommended, patients typically follow a treatment schedule that is designed to meet their healthcare goals.
Are There Any Risks?
Like any medical treatment, HBOT carries potential side effects. Many are mild and temporary, but knowing the risks helps you make an informed decision. Pressure changes inside the chamber may cause ear discomfort or pain, similar to what you feel during an airplane flight. Some people experience temporary vision changes, which usually fade after treatment ends. Sinus pressure and fatigue are also possible.
Since safety is a priority during HBOT, clinics should enforce strict rules throughout treatment. You will be asked to remove items from your pockets, such as lighters and some electronics, before entering the chamber. This reduces the fire risk associated with high oxygen levels, and it helps prevent objects from interfering with the treatment environment.
Although HBOT can benefit many patients, those with certain conditions require evaluation before treatment. Lung diseases or recent ear surgery typically impact candidacy. Your care team will review your history, and they will explain any precautions that apply to you.
Learn More About HBOT
Hyperbaric oxygen therapy is a specialized treatment that uses increased oxygen levels to support the body’s natural healing processes. While HBOT can be beneficial for certain medical conditions, it is not appropriate for everyone, and a healthcare provider should always guide treatment. Understanding how the therapy works, what it treats, and the possible risks helps patients make informed decisions about whether HBOT is right for them.
