Brief Summary:
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.

Standard Care Group
Subjects who will undergo only standard wound care management.
Hyperbaric Oxygen Therapy Group
Subjects who are selected for adjunctive hyperbaric oxygen therapy in addition to standard wound care intervention.

Primary Outcome Measures :
  1. 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.
