In the mid 1980's I worked in an emergency room in Covington, Louisiana, and a little old lady was brought in, middle of the night, in full cardiac arrest. Bad heart attack. I ran the resuscitation for her and ended up having to put a tube into her in order for her to breathe, and got her back and was really happy because that was a difficult resuscitation. The next day I got a call from my college roommate to thank me. It was his grandmother's life I saved. She lived another six years after that. That's the one I remember most clearly, because I wasn't going to give up even though I had no knowledge of who she was. I gave her another six years of life.
