Sorry you had to go through that. I’m sure you felt kind of helpless and it seems like an AED would have been a lifesaver, but probably not. The times when they are lifesaving is cases of electrocution, drowning, choking, or other times when a young and healthy heart is stopped by an accident. Hearts that stop from heart disease are a whole nother thing. I was an EMT on a volunteer fire/ems service for six years or so back in the early nineties. I’ve done CPR dozens of times, and in all those cases we only restored one victim to a perfusing rhythm. She lived and almost fully recovered.
I estimate that maybe 20 of those were before we got an AED, and a dozen or so after we got an AED. Probably 1/2 of that dozen, the AED did not detect a shockable rhythm, so would not let us shock. So I’ve seen 12 or so people treated with an AED… 5-6 people shocked, and we got one back. Even after a perfusing rhythm is restored, the patient needs hi concentration oxygen, and rapid injection of cardiac drugs to improve outcome. They will often have to be intubated. Quite often despite all these interventions they die anyway. We had a guy collapse at work and they got him back, but he was brain damaged badly and could barely walk or talk for the rest of his life. Other people may have experienced a higher success rate YMMV.
So what I’m getting at is IMO you can’t carry enough kit in a back country scenario to provide proper care for a cardiac arrest. You need an ambulance for that , and then rapid admission to an ER and an ICU. And the percentages of restoring a cardiac arrest victim to full function are not super high. I mean they have bad enough heart disease that it stops their heart.
I’m not unsympathetic or unfeeling about it, just realistic. I’m 67. I have ticker issues myself, and cardiac arrest is most likely the way I’ll go. I’ve said often and I really mean it, that I’d like to go on a hunting or fishing trip, although that’s terribly inconsiderate of my partners. Ideal for me though.
