Hyperbaric Oxygen Therapy (HBO) If you experience a wound that hasn’t healed in four weeks, ask your physician to evaluate your wound for HBO. Wound conditions that may benefit from HBO include: Air or gas embolism Carbon monoxide poisoning Compromised grafts and flaps Crush injuries Decompression sickness Diabetic wounds of the lower extremity Enhancement of healing in select wounds Exceptional blood loss anemia Gangrene Intracranial abscess Necrotizing soft tissue infections Post-radiation injury Refractory osteomyelitis Thermal burn How It Works Lying in the transparent cylinder of the hyperbaric oxygen chamber, you have an unobstructed view outside and the ability to talk to an attendant through an intercom. During treatment, you may relax by sleeping, listen to music or watch television. As the chamber is gradually pressurized, you may feel a “fullness” in the ears similar to that experienced when diving under water or flying in an airplane. Trained attendants can assist in trying to help you overcome this temporary sensation.
