Definition of Hyperbaric Oxygen Therapy: The patient breathes 100% oxygen intermittently while the pressure of the treatment chamber is increased to greater than one atmosphere absolute (atm abs). Current information indicates that pressurization should be at least 1.4 atm abs.   This may occur in a single person chamber (monoplace) or multiplace chamber (may hold 2 or more people).  Breathing 100% oxygen at 1 atm abs or exposing isolated parts of the body to 100% oxygen does not constitute HBO2 therapy.

The following indications are approved uses of hyperbaric oxygen therapy as defined by the Hyperbaric Oxygen Therapy Committee. The Committee Report can be purchased directly through the UHMS.
