"Of those that do survive, more than half of them have brain damage." I've read a theory that if as soon as someone as heart attack you put ice on his head you lower the risk of permanent brain damage. If I'm not mistaken there's been a doctor / hospital / ambulances allowing to test this theory in the U.S. (don't remember which one) and they had apparently statistically significant better results when ambulancers did immediately put the head in ice. Our brain is one heck of a CPU and when the blood doesn't cool it it starts melting fast apparently : ( Lowering temp to 32 deg certainly helped but apparently every second counts: the faster you put the head in ice, the lower the brain damage. So while someone is trying to do CPR, someone else should go fetch lots of ice. Interesting "feeling lucky to have a great life that I just want to continue to live". Welcome back!
