Has anyone here been in that situation where, choosing to NOT intervene, they watched as the affected person died?
I bet not.
And whoever may have probably has a lot to teach us.
Last week, I was riding on the Engine when a cardiac arrest was dispatched. We were the closest unit by far, just happened to be returning from a fire call. We pulled up, a crew of 3, with me and another medic, and our driver was a BLS provider.
Went in the EMS compartment and there. was. no. equipment. None. We had left for a house fire, and the EMS equipment was on the other unit that we usually staff.
So we looked at the dead guy on the porch, pulled him down on the ground and started hands-only CPR. We actively chose NOT to do any kind of ventilations, continuing compressions until the medic unit arrived.
He started breathing on his own during the CPR anyway, so we just kept on. When we finally got him on the monitor (prob after 4 minutes or so) he was in vfib, so we shocked and converted him to NSR. Score!
Anyway. I would have made the same decision and been satisfied with it even if he died. He looked about 70, had a PEG tub and a zipper scar on his sternum. If his time had come, he had too many risks for having something communicable for me to risk any sort of mouth to mouth. Here's me laying down an "I would never."
I really would never do mouth to mouth on a stranger if I could possibly avoid it.
And about your actual question, firetender, I think that choosing to do nothing has a lot to do with turning your back, so the people who make that decision don't typically watch the person die.
I've decided not to get involved because of my own reasons plenty of times: pregnancy, babies, small children and being late can really wreck a samaritan's day. Each time, and in each situation, I've ultimately been comfortable that I did all that was reasonable. I think people get to decide on their own whether to get involved, with no guilt needed if they don't want to.
There is a lot of sense in the question though: What's an EMT-B going to do at the basic traffic accident while they wait for the ambulance? Not much, really. I typically don't stop, either...but I'm usually travelling heavy.
