As in other maladies characterized by massive wounds or tissue destruction, hyperbaric oxygen treatment can be a valuable adjunctive therapy but is not widely available.
In hyperbaric chamber therapy, the patient or experimental subject is placed in what is essentially a decompression chamber and exposed to air with slightly higher-than-normal oxygen content.
Fife's interest in clinical hyperbaric medicine lead to several research projects to look for new indications for the use of hyperbaric oxygen therapy.
