Hyperbaric oxygen therapy is essentially a method of treatment which relies on its ability to increase partial pressure of oxygen in tissues of the body. Hyperbaric oxygen therapy is actually recognized by Medicare as a reimbursable treatment for 14 different conditions, including Lyme disease, which was first recognized in 1975 after researchers investigated a high incidence of juvenile rheumatoid arthritis near Lyme, Connecticut.

Another condition for hyperbaric therapy is radiation necrosis, which is a focal structural lesion that usually occurs at the original tumor site. Radiation necrosis is a potential long-term central nervous system complication of radiotherapy or radiosurgery, but hyperbaric treatments can help abate the symptoms and help people feel better.

Hyperbaric oxygen therapy increases the oxygen transport capacity of the blood, which means going through the treatment helps people feel better in the muscles, tendons, joints, and ligaments. Many athletes recover from injuries or prepare for extensive competition through hyperbaric oxygen therapy, because of its many benefits on the human body.
