I'm wondering about for how long the brain can go w/o oxygen, before
braindamage occurs? (And also, how the damage occurs..)
For example, if I breathe out as much air as possible, in less than 10
seconds I will feel the need to inhale. Does this mean that if I could go on
longer w/o inhaling, something ..bad would happend?
I've read reports of people inhaling pure N2O (as opposed to the dental 30%/
70% mix, or whatever amount it is :) and holding it in for minutes, would
this mean that some sort of damage occurs?
