What We Do

Hyperbaric oxygen therapy uses 100 percent oxygen, administered at an increased atmospheric pressure. It increases the amount of oxygen that is carried by the blood, to areas of the body with compromised blood supply. Other effects of hyperbaric oxygen therapy include growth of new vessels, optimization of white blood cell function, and restoration of tissue metabolic balance.

Using a large, 8-person chamber, as well as three single person chambers, our unit offers:

  • Elective hyperbaric therapy
  • Urgent care hyperbaric therapy
  • Wound assessments
  • Transcutaneous oximetry

The Hyperbaric Medicine Unit follows treatment guidelines that have been established by the Undersea and Hyperbaric Medical Society (UHMS).​

Conditions Treated

  • Acute thermal burn injury
  • Air or gas embolism
  • Arterial insufficiencies (central retinal artery occlusion; Enhancement of healing in selected problem wounds)
  • Carbon monoxide poisoning
  • Carbon monoxide poisoning complicated by cyanide poisoning
  • Clostridial myositis and myonecrosis (gas gangrene)
  • Compromised grafts and flaps
