Summary: After brain injury, many blood capillaries around the are of cell death become torn. The blood plasma then leaks out causing swelling in the surrounding brain tissue, squeezing it like a sponge and so reducing blood flow and therefore nutritional supply. Without this essential nutrition, the brain's electrical activity becomes diminished and signals can not be effectively rerouted. Unfortunately the tiny tubules leading to the capillaries also become so constricted that the red blood cells can not get through to heal the torn capillary walls. Hyperbaric Oxygen treatment is the giving of oxygen under increased atmospheric pressure, (i.e. above the one atmosphere at which we all live) which dramatically increases the oxygen carried in the blood plasma. The treatment is carried out in a Hyperbaric Oxygen Chamber.
