I've attended 3 or 4 medical emergencies, and was only asked for my credentials once (on a BA flight). On that occasion, it was actually my gf of the time who was unwell, so it was especially stressful, especially since the whole thing was rather protracted. The CSD offered to move us up to F, but that became (medically) impractical for various reasons. Was given half a case of wine by BA as a thank you, which was appreciated, but since I'm teetotal, I didn't benefit personally.

On NW, attended a man who collapsed, but I'm pretty sure it was a vaso-vagal. Monitored him a few times, and he was fine, but I advised him against driving on arrival at LHR. I was given a cert for 5k miles, which I couldn't redeem, since European residents couldn't join NW at the time.

Most recent case was about 6 months ago -- I was in F from BOS to ORD on AA, a sweet old lady lost conciousness -- not diabetic, but revived after a few minutes after being given some orange juice and I don't think it was anything serious. I monitored her regularly throughout the flight to make sure she was OK, which she was. She said that what brought her round was my 'unusual accent', which she couldn't place -- given that I speak Standard English, I found this rather bemusing! The FA took my details, but I heard nothing back.

I agree with one of the posters above: the CC/FAs are very professional, which is just as well, since it is extremely stressful attending an emergency mid-flight, taking BPs is v. difficult etc. An acknowledgement letter would be a very nice and classy thing to do -- BA was the only one to have done that in my experience.

Most difficult scenario I heard of was a friend who (when an intern) diagnosed a ruptured ectopic pregnancy in a woman, and asked for an emergency diversion. Pilot told him later that his diagnosis had been spot on, and the patient was recovering well.
