Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBO) is used to treat burns, carbon monoxide poisoning, trauma injuries, infections, amputations and complications from cancer and diabetes. Developed in the 1940s, the technology was originally used to treat deep sea divers who suffered from decompression sickness.

Our Leon S. Peters Burn Center at Community Regional Medical Center in downtown Fresno is home to the area’s first board certified staff and two hyperbaric oxygen chambers.

Treatment takes place inside a sealed tubular chamber that creates an environment where the entire body is under increased pressure and patients breathe 100% oxygen. The high concentration of oxygen combined with increased atmospheric pressure causes large amounts of oxygen to be dissolved into the blood – promoting tissue growth and helping persistent wounds to heal, or heal faster. The therapy allows for more microvascular blood vessel growth, which promotes healing in chronic non-healing wounds. Growth of white blood cells is stimulated, while growth of certain bacteria is slowed. It also reduces certain severities of swelling.

HBO therapy is normally painless. You lie comfortably in a chamber, where you can watch TV, listen to music or nap as if you were in your own bed. And you’re always under staff supervision, with the ability to communicate to staff.

Non-emergent referrals can be scheduled Monday through Friday, 7 a.m. to 4 p.m. Please call (559) 459-3870.

Emergent referrals can be scheduled at (559) 459-4220.
