7/10) I was returning for my second year of medical school and a flight attendant came on the PA asking if there was a doctor on board. Since I was only a student, I sat in my place. A few minutes later, the request was asked again and I thought that I should at least see what can be done. I told a flight attendant that I was only a student and going into my second year and the flight attendant took me to the business class where a woman had passed out and was slowly regaining consciousness. Inside, I was thinking, holy shit, I haven't even seen a patient yet and here I am having to take care of one.
The woman just had a falling spell and had hit her head. A few moments later, a doctor showed up and told me to check her eyes to look for signs of a concussion, get her pulse, talk to her, and administer oxygen. He did the paperwork. A few minutes later, the woman was able to get up and go back to her seat and the doctor said I wasn't needed anymore.
The woman was fine, no concussion, very responsive, pulse was a little on the low side. After landing at our destination, she was taken to a hospital for further examination and I caught my connecting flight.
8/10) All my father's life he waited for the moment when this would happen. A few years ago it actually happened, a guy collapsed on his way back to his seat, in a movie theatre. The people he was with shouted for help, and finally my dad rose to the occasion, he ran up to them and halfway there, another doctor swooped in before him.
9/10) OK, so not a doctor, but on a flight from Sacramento to Denver a man had passed out and was unresponsive. Flight attendants fly into action - including attendant who is leaping from aisle armrest to aisle armrest to get to the front of the plane (over those that are in the aisle gawking). After their normal tactics don't work, a call for any doctors on the plane comes over the intercom. I kid you not, five people pop up and head to the front of the plane with their carry-ons - which contain emergency medical supplies. They work on the guy for about another 15 minutes, pilot has to drop the plane to 10,000 feet quickly (oh, that was fun) - which is apparently standard procedure during a medical emergency (don't want to get the bends from being too high altitude). Guy regains consciousness, but barely able to move. He's whisked off the plane once we arrive at the terminal - ambulance waiting on the tarmac.
Most exciting hour and a half flight I've ever had. Hoping I never have one that is any more exciting.
10/10) My sister-in-law is a nurse. She had to help out once when a diabetic who wasn't monitoring his blood sugar passed out. She gave him some OJ and some pretzels, and just kept an eye on him until we landed and paramedics met us at the gate. The flight crew was really grateful and gave her a couple bottles of wine (full bottles; I think they were selling them from a catalog, or maybe they were for first class passengers) and some other little things as a thank you!
