The purpose of this study is to investigate the efficacy of an optical device designed and developed to quantitatively monitor blood flow velocity of wound sites. It is hypothesized that the blood flow velocity of the wound site will provide critical information on the efficacy of hyperbaric oxygen therapy.

Primary Outcome Measures:
  • Blood flow velocity measurements [ Time Frame: 5 months ]
    Effectiveness of blood flow velocity measurements of wound sites to assess tissue viability with a novel optical device. Comparison between the responses of patients treated with hyperbaric oxygen therapy and those treated by other means will be made.
