Hyperbaric oxygen therapy was initially used to treat deep-sea divers with decompression sickness, known as "the bends." Over the past few decades, the role of this therapy has expanded to include the treatment of a number of other medical conditions, particularly some that do not respond to other therapies. Marvin Heyboer, MD, discusses healing strategies for diabetic foot ulcers, venous stasis ulcers and injuries from radiation therapy. Heyboer, an associate professor of emergency medicine at Upstate Medical University, is medical director of wound care and of hyperbaric medicine at Upstate.
