Hyperbaric Oxygen Therapy (HBOT) is considered in the documentary ‘Coma’ that tracks several victims. One victims brain couldn’t process sound, for me it’s the right side of my body. They noticed progress after HBOT. A victim couldn’t walk in the water unaided before but could after. For my recovery I too noticed improvement after HBOT. My twin brother put me on a course at the established therapy centre http://www.hypermed.com.au. I think my brain started to improve after each session in an oxygen chamber.
The person who administered HBOT was a proven Australian therapist by the name of Mal Hooper. I suspect HBOT began my recovery. Several friends contributed to the costs of HBOT. So my advice to other coma victims is definitely try it. For me it was to be put in an oxygen chamber for about an hour 4 times in a month, the belief being that oxygen is central to the health of cells. Especially brain cells.
