I do surf lifesaving to keep fit and we get taught you can only last 3 min without oxygen before you get brain damage is this true?

the image i attached is from my Red Cross First aid Manual. I would imagine that a few minutes could be added to the numbers since the people you are looking after probably have a higher then average O2 efficiency(sp)
im gonna be meeting with my instructor next weekend so i will ask him then.
still i would say that 3minutes is a bit short but i could be wrong

to be safe i would try to make sure they are back at the surface in less then a minute :hungover

good luck
