I thought that VO2 was not just the ability of a person to transport O2 around the body. (dependent on respiration, circulation, RBC, heamaglobin etc...) but also how they metabolise it on site.(myoglobin in the muscle, levels of different metabolic enzymes ....). This gives gives max possible usage of O2 in one minute not how much can be transported around the body. Remember also that this may be dependant on available O2 and so vary according to which gases and their concentrations are breathed. If a person has a low VO2 then that may be due to other factors besides circulation and probably cannot be used as a definite factor in calculating risk of DCS John M.
