Lynn, do you mean Hyperbaric Oxygen treatments? That is what Mel received a few years ago to prepare is jaw for a tooth extraction and root canal, after having had radiation the summer before. Hyperbaric oxygen is putting the whole body under pressure in a sealed tank while receiving pure oxygen. It's like they do with divers who have the bends. It aids regrowth of blood capillaries . It's difficult for some people due to claustrophobia but it works well. Mel's jaw healed from the extraction without a hitch. glad they are helping your daughter with it. There is an increasing list OC conditions it helps.
