What are the Beneficial Mechanisms Associated with Hyperbaric Oxygen Therapy?
Several beneficial mechanisms aye associated with intermittent exposure to hyperbaric doses of oxygen. Either alone, or more commonly in combination with other medical and surgical procedures, these mechanisms serve to enhance the healing process of treatable conditions. 1. HYPEROXYGENATION provides immediate support to poorly perfused tissue in areas of compromised blood flow. The elevated pressure within the hyperbaric chamber results in a 10-15 fold increase in plasma oxygen concentration. This translates to arterial oxygen values of between 1,500 and 2,000 mmHg, producing a four-fold increase in the diffusing distance of oxygen from functioning capillaries. While this form of hyperoxygenation is only a temporary measure, it will serve to buy time and maintain tissue viability until corrective measures can be implemented or a new blood supply is established. 2. NEOVASCULARIZATION represents an indirect and delayed response to hyperbaric oxygen exposure. Therapeutic effects include e
