Idea: Does your island association have AED(s)? Do you know where it is? Not the OPs original problem, but CB thought they would die, maybe not. I'm fortunate enough to know of one within 1000 feet of my house. Family members/friends would have no problems getting to it if needed.
Get a few, sprinkle around the island, on the neighbors front porches, for example. I'm not trying to create a debate point.
