Holy guacamole, Marvin! SO glad you're OK, and I get everything you're saying. So many down here don't have the radio contact, local phone service, AED available, nada. Don't even know where CIMA is. I've seen the Kino clinica up close and personal: I once had to personally run to the farmacia from there to purchase IV tubing/needle for a friend before he could get a much-needed infusion of fluids.
We do have an AED and oxygen in Dos Palmas (on my screen porch, actually), as well as people that know what to do. But defibrillation won't fix blocked coronary arteries. You are so right that your outcome may have been different in Kino.
