HBOT uses a pressure chamber. You go into the chamber and are sealed in, and then the pressure is slowly changed. You stay in it for a certain amount of time at a specific pressure, then the pressure is slowly changed back to normal before you can exit the chamber. At least, this is my understanding of how HBOT works...
The purpose of this is to force oxygen into the cells and tissues of the body. Since we know Lyme doesn't like high-oxygen environments, anything we can do to increase oxygenation of the body should help in our battle against this nasty bug.
Also, one caution about HBOT is to make sure you are taking antioxidant supplements - if one is deficient in antioxidants, the HBOT procedure generates a lot of oxygen free radicals and may cause problems.
