If it were me unconscious on the floor, I'd take a pediatric neurologist that "hasn't done hearts" for 20 years over a flight attendant with 8 hours of "first aid" training.
Definitely. I'd rather have any medical professional (any doctor, nurse, emt, paramedic, etc.) attending me in that situation rather than someone whose medical training consists of a first aid course and maybe a CPR certification.
Oh, for sure. I certainly don't mean to disparage her skills, just that 'doctors' come in a lot of different varieties, and not all of them retain general medical skills.
I remember a friend who became a paramedic. My home state brought in ambulances-for-everybody. If you wanted an ambulance, the dispatcher couldn't say no anymore, you got an ambulance. And for people on low-income cards, those ambulances were free. So my friend got called out to a lot of junk calls (his term: "coughs, colds, and sore holes"), and said that it was a problem for the paramedics because their skills rusted - some paramedics reported only seeing one heart attack in a year, and they have to pause and think what needs to be done again.
Medicine is very much a 'use it or lose it' discipline, at least when it comes to the details.
