Hyperbaric oxygen therapy (HBOT) or hyper oxygenation is a method of administering pure oxygen (O2) at a higher atmospheric pressure in a pressurized chamber in order to treat a medical condition. Effects of HBO on body can be divided into primary or direct effects and secondary or immediate effects. Primary effects include hyper oxygenation of the tissue due to increased O2 carrying capacity and O2 diffusion in tissue fluid. These properties could be effectively used in cases of severe blood loss anemia, crush injury, compartment syndrome and graft or flap salvage. It could also be useful in cases of air embolism where HBO gradient favours gas leaving out and oxygen moving into the bubble leading to decrease in the size of the embolus.
Secondary effects of HBO include vasoconstriction, angiogenesis, fibroblast proliferation and increased leukocyte oxidative killing. Vasoconstriction leads to decrease in edema which is helpful in conditions like crush injury, compartment syndrome and acute burns. Angiogenesis is useful for graft salvage, osteoradionecrosis, radiation endarteritis obliterans and chronic wounds. Chronic osteomyelitis and necrotizing soft tissue infections improve by increased leukocyte oxidative killing mediated by HBO. (Journal of Pakistan Association of Dermatologists 2009; 19: 164-167.)
