From what I am understanding, knowing CPR won't be important at all, unless there is a difibrillator nearby. I am eager to be corrected, but some of the informed posts make it sound like CPR in the backcountry is an excersize in futility.And, as I understand it, this a daily preventative anyway - if I run into someone having a heat attack, getting them off the mountain and knowing CPR will probably be more important than trying to give someone in the processes of having one a couple of aspirin anyway
On the otherhand, giving an aspirin can help the survival rate, or at least lessen the damage of a mild heart attack. Or not?
