I don't know if this link would be of use to you or not, but hyperbaric oxygen is used in problem healing. In our area, a medical school in Ft. Worth used this several years ago in some type of study. I assume you would probably need some direction with this, either a doctor or somebody who knows what they are doing with it. It is done in a chamber as far as I know...
