I'm not sure I understand the question after reading the text but I'll answer the subject. There have been a few emergency situations but a couple of them are very memorable.
A young woman had an accident in which the brachial artery in her arm was cut. Someone called 911 but nobody was actually doing anything as blood was spurting from her arm. I put her on the ground and soothed her while I made a compression bandage to slow the bleeding. The EMT said I saved her life but I doubt that. As far as feeling anything I don't recall anything except a need to comfort the woman and a sense of urgency for a professional to arrive. I was on auto-pilot.
The second one was a workplace accident. A man was splashed by a corrosive cleaning agent. Nobody was doing anything helpful and the man was in agony. A co-worker and I got the man undressed and got water hoses to rinse the chemical off and cool him down. We kept him talking to keep him from freaking out as parts of his skin were peeling away and he was scared to death. Auto-pilot again. What I was thinking was basically why weren't precautions taken to keep something like this from happening, where is his supervisor, why is his foreman standing by the exit talking on the phone, and why isn't whoever is trained for this situation here handling this. Also stressing about why it was taking so long to get an ambulance. I had just gotten one of his co-workers to get my phone out of my pocket and call 911 when the EMTs walked in the door. Afterwards I (and my co-worker) felt anger and frustration that it took so long to get emergency help and that this man had been instructed to do something that was so obviously unsafe.
I'm not sure if that's the kind of thing you were looking for... hope it helps you.
