Hyperbaric Oxygen Corrects the Peri-Wound Microvascular Flow

The efficacy of hyperbaric oxygen therapy (HBOT) to facilitate wound healing in diabetic lower extremity ulcers is well established. The impact of HBOT, however, on tissue perfusion and flow is not known. The purpose of this pilot study was to ascertain the effects of HBOT on the microvasculature of chronic wounds, as assessed by fluorescent angiography.
