You defibrillate someone in an unstable arrhythmia to convert them back to a stable rhythm but you can’t do that if there isn’t anything there at all.
Good point. And even if it worked like that they'd
never just hop up, take a deep breath and act like they just had the wind knocked out of them at the worst.
As for people freezing in place, the Army taught me that any action is usually better than no action at all. I have been in several situations where everyone just stood there with their thumb up their forth point of contact while I'm doing something.
I'll never forget the traffic accident that happened one afternoon right at the end of day formation. one of my missile tech guys was an EMT before that and he took charge. he did things I never would have thought of then (like killing the ignition for each vehicle) and took charge. I outranked him by quite a bit he looked at and yelled, "Call 911" directly at me. I immediately ran to the orderly room to get someone to call. Later, he told me he yelled directly at me because he assumed I wouldn't argue with him and would know if one person is controlling things, it's best to keep it that way for the moment. I tired to him in for an ARCOM but pre-9/11 awards were hard to get approved then. I did give him props in the formation the next evening.
My wife has a good head on her shoulders as well (well, other than that boneheaded move of marrying me, that is), and once we were going out of a restaurant and a old woman just fell down off the curb onto her backside (thankfully only some scrapes). We immediately jumped into action, and the people who worked there didn't want to get involved. I bet if you watched it happen, you'd have thought were both EMTs. No, but we both handle injury claims for an insurance company and she worked in a hospital for a few years before that.
We got her up, checked her out, I got the rest of her party (both elderly and another who had diminished capacity issues) into their car and then we got her in with them with instructions on what to do next.
I would say I was proud of my wife that day, but that's just the kind of person she is. We don't back away from what is right and the sad part is so few actually will do that. Everyone else either locks up, doesn't want to get involved, or is too busy live streaming it for views (had someone been doing that in the case of that lady, I'd have maybe snatched the phone and sent it down the embankment).
One year on the 4th of July, we had friends over and some idiot down the street launched fireworks into what was at the time an open field of high grass (here, it's usually quite dry that time of year). A fire immediately caught and myself and the males at my place grabbed shovels and ran across the road to get to work to put the thing out. The idiots who caused the whole mess just stood there and none ever came down to help. The fire department came up as we were getting it under control and demanded to know who started it. We all said, "Wasn't us," while looking in the direction of those fools
still standing there, but we didn't roll on them.
Everyone should go through life wondering, "what would I do if ______ happened right on front of me?" and thinking how they'd react, just in case it does.
