I am a flight paramedic. I teach PHTLS, AMLS, ACLS, PALS, CPR and EMT classes. I won't go too much into the rescue training, but if there is a wilderness, a cliff, water, or a vehicle involved, I have a pretty good idea about how to get you out.
You are right about most MDs, and their ability to effectively work in an emergency situation. I've had the displeasure of having to manage their egos and lack of emergency skills while trying to manage a critical patient on several occasions. They are typically as worthless as tits on a boar hog. On a recent domestic vacation flight, the flight attendant requested medical personnel to assist one of the passengers who was experiencing a medical emergency. A surgeon and myself went to help. It became apparent to me that the passenger needed airway management, so I sent the doc to get an "airway kit" if there was one on the plane. Several min. later, super doc shows up with an O2 cylinder- that's it. No mask, no nose hose, there wasn't even a regulator on the cylinder. Sweet, I thought- if this guy quits breathing, I'll just hit him over the head with this cylinder! Thanks for the help doc! Many ER docs, and on occasion other docs, are an exception to that rule.
That brings to light another important point. Even with a bunch of knowledge and training, I am pretty ineffective without an ambulance or airplane (my own!) full of equipment. Sure, I can keep my cool, preform effective CPR for a while, and bandaid some scrapes, but to preform to my abilities, I need a bunch of equipment.
