What is this Hyperbaric Oxygen Therapy?

Chamber Photo 1Hyperbaric (hi-per-bare-ik) medicine is essentially the study of medical and physiological problems, and therapeutic applications of greater then sea level barometric pressure. Hyperbaric oxygenation is accomplished by having the patient breathe 100% oxygen either by face mask, headhood or endotracheal tube in a full body, compressed air (or oxygen pressurized monoplace) chamber. Hyperbaric oxygen (HBO) is simply intermittent, short term, high-dose oxygen inhalation therapy.

Chamber Photo 2A century of research in oxygen administration has established that the effects are dose related, and the hyperbaric environment merely provides the opportunity to give higher doses than can be achieved at sea level. How does this occur? The air we breathe is approximately 20 percent oxygen and 80 percent nitrogen. Therefore, if pure oxygen is breathed, on the surface, the inhaled oxygen concentration is increased by five times. In a hyperbaric chamber inhaled oxygen transported to the tissues will increase 10 to 20 times. Today hyperbaric oxygen is the primary treatment for decompression sickness and arterial gas embolism. It is not used as a substitute for another form of traditional therapy. Rather, it is used as adjunctive treatment for disorders, which demonstrate a sound physiological basis for its use. Hyperbaric oxygen therapy can promote healing and aid in the treatment of disorders involving oxygen deficiency

Although HBO is well known for its effectiveness in treating decompression illness, it also has beneficial healing effects for other conditions including:

  • Carbon monoxide poisoning
  • Gas gangrene
  • Chronic bone infections
  • Select non-healing wounds
  • Radiation tissue damage
  • Arterial insufficiency, such as crush injuries and compartment syndromes

    What follows is a list of what are considered "approved" indications for hyperbaric oxygen therapy:

  • Air or Gas Embolism
  • Carbon Monoxide Poisoning and Smoke Inhalation Carbon Monoxide Complicated by Cyanide Poisoning
  • Clostridial Myonecrosis (Gas gangrene)
  • Crush Injury, Compartment Syndrome, and Other Acute Traumatic Ischemias
  • Decompression Sickness
  • Enhancement of Healing in Selected Problem Wounds
  • Exceptional Blood Loss (Anemia)
  • Necrotizing Soft Tissue Infections (Subcutaneous Tissue, Muscle, Fascia)
  • Osteomyelitis (Refractory)-Cierny and Mader classification system
  • Systemic or local factors that affect immune surveillance, metabolism, and local vascularity
  • Radiation Tissue Damage (Osteoradionecrosis or soft tissue radiation necrosis)
  • Skin Grafts and Flaps (Compromised)
  • Thermal Burns
  • Adjunctive Hyperbaric Oxygen in Intracranial Abscess

    Other indications, which are currently being researched (but not widely accepted):

  • Closed Head Injury
  • Traumatic Brain Injury
  • Cerebral Palsy
  • Stroke
  • Near Drowning
  • Myocardial Infarction (heart attack)
  • Chronic Fatigue (as seen in HIV)
