The Hyperbaric Oxygen Therapy (HBOT) Unit at GBMC addresses non-healing chronic wounds, specific infection types such as necrotizing infections and osteomyelitis, osteoradionecrosis (bone damage caused by radiation therapy) and other soft tissue radiation injuries. HBOT is a modality of treatment in which patients breathe 100 percent oxygen in an enclosed chamber at two to three times atmospheric pressure. Oxygen dissolves into the blood plasma causing an increase in tissue oxygenation, stimulating healing of tissues, forming new blood vessels, controlling infections and regenerating new, healthy tissues.

HBOT can be delivered in either multi-place or monoplace chambers. GBMC has six active monoplace chambers, making it the largest hospital-based HBOT unit in the region.

Coverage for Hyperbaric Medicine is provided by GBMC physicians who have completed training in an approved Undersea and Hyperbaric Medical Society (UHMS) Program and meet the GBMC credentialing criteria for privileges in hyperbaric medicine. Our physicians work closely with registered nurses and technologists who have received specialized training to deliver and monitor HBO treatments.
