indication s of hyperbaric o2!!

Hyperbaric oxygen (HBO) treatment is gaining popularity as the definitive therapy for a growing number of disorders, including

decompression illness, arterial gas embolism, carbon monoxide poisoning, clostridial infections, crush injuries, diabetic leg ulcers, skin graft failures, refractory osteomyelitis, thermal burns, necrotizing soft tissue infections, and osteoradionecrosis.

In the US, hyperbaric oxygen therapy for decompression sickness is guided by the Navy Treatment .

The prescribed treatments are very effective, especially when recompression is begun promptly. The purpose of the therapy is two-fold: to promote inert gas elimination and to help cause a decrease in bubble size. The treatment outlined by the tables also provides oxygen to the damaged tissues, treats platelet and clotting damage and allows excretion of harmful metabolites.

The oxygen reduces CNS edema and provides a high oxygen gradient (2000 mm Hg) for the ischemic tissues.
