Possibly a dumb question, but wouldn’t the other thing you do be to carry the guy out on a stretcher? It seems like her dad was able to get into the car but that last bit where he got out at the hospital and walked was just too much. Or do you think the stretcher would make zero difference?

Yes! These patients are critical and we would not let them ambulate themselves to the ambulance, we would insist on loading them and moving them ourselves to limit exertion. Extra exertion could tip them into cardiac arrest.
