Rebreather World - View Single Post - How much oxygene does a uncounsious diver use per minute?

I'm not sure where you are trying to go with this. Bear in mind I'm not a doctor or biologist. Obviously, a diver metabolises 1 litre/min of oxygen, though there is some oxygen in the lungs and bloodstream. However, if he is not getting that then the body uses the less efficient anaerobic respiration to generate energy, producing lactic acid. In cold water, bradycardia slows the heart by as much as 50% and vasoconstriction shuts down the peripheries to concentrate blood in the critical organs to maintain life. People have been known to survive 15 minutes or more unconscious in cold water, but it is best not to count on this.
