How Hyperbaric Oxygen Therapy Works

Understanding the role of oxygen and pressure

Hyperbaric oxygen therapy uses increased pressure and medical-grade oxygen to support the body’s natural healing processes.

What is hyperbaric oxygen therapy?

Hyperbaric oxygen therapy, often called HBOT, is a medical treatment that helps increase the amount of oxygen available to the body.

During a session, individuals breathe medical-grade oxygen inside a specially designed chamber where air pressure is safely increased under medical supervision. This combination of oxygen and pressure allows oxygen to be delivered more efficiently throughout the body than it can be under normal conditions.

Why oxygen matters

Oxygen plays an essential role in nearly every function involved in healing and recovery.

It supports tissue repair, helps the body manage inflammation, and plays a role in the body’s ability to resist infection. In some situations, injury, illness, or compromised circulation can limit how much oxygen reaches certain tissues. When oxygen delivery is reduced, healing processes may slow, and the body may have a harder time repairing itself.

How pressure changes oxygen delivery

Pressure is what makes HBOT different from breathing oxygen at normal atmospheric pressure.

Under increased pressure, oxygen is able to dissolve more readily into the body’s fluids, including plasma. This allows oxygen to reach areas that may not be receiving enough oxygen through normal circulation alone.

By improving oxygen availability at the tissue level, hyperbaric therapy helps create an environment where the body’s natural repair processes can function more effectively.

What increased oxygen supports in the body

By increasing oxygen availability, hyperbaric oxygen therapy may support several important biological processes.

Infection resistance

Supports the body’s ability to resist infection as part of normal immune function.

Tissue repair

Supports tissue repair processes, including collagen formation involved in recovery.

New blood vessel development

Supports processes involved in new blood vessel development within healing tissue.

Oxygen-compromised areas

Supports recovery in areas where oxygen levels may be reduced due to impaired circulation.

These processes are part of the body’s normal response to injury and stress. HBOT is designed to support these mechanisms, not replace them.

What a treatment session is like

Most sessions feel quiet and comfortable, with continuous monitoring by trained staff.

Each session takes place in a clear, medical-grade chamber designed for comfort and safety. Patients typically lie down and rest while breathing oxygen as the chamber gradually reaches the prescribed pressure.

Some individuals notice mild ear pressure during this phase, similar to what is experienced during changes in altitude. This sensation is usually brief and can often be relieved by swallowing or gently clearing the ears.

Once treatment pressure is reached, many patients relax, listen to music, or watch a movie. Pressure is gradually returned to normal at the end of treatment, and most people are able to resume normal daily activities.

A thoughtful, individualized approach

Hyperbaric oxygen therapy is not a one-size-fits-all solution.

It is used as part of an individualized approach to care, guided by medical oversight and patient education. Our focus is on helping people understand how HBOT works, what to expect, and whether it may be appropriate for their specific situation.
