This picture wasn't far from truth for me. I graduated nursing school in 1979, and began ER work, which I did for a couple of years. I had always worked part time as a musician, and so after getting married in 1981, I went into Home Health.
In 1984, after meeting the son of my patient, who sang barbershop, I went to visit his group. In less than a year, I became the director of this little chorus in Oak Park Illinois. We put on a show in the fall of 1985, and after we opened the show in football uniforms, we left the stage, and had some quartets singing, so I changed into my tuxedo, and snuck into the back of the auditorium, planning to watch until intermission.
After a couple of minutes, one of the chorus members came to me, and told me there was a sick lady in the audience, near the back. I ran over to her, she was slumped in her aisle seat, and not breathing. Fortunately, I'm a big guy, picked her up, laid her in the aisle. I tried to breathe for her several times, and it was obvious her airway was obstructed.
I sent the chorus member for help and 911, and after about 2 minutes of repositioning her, and finally performing an abdominal thrust, a large piece of food (eww) came out, with a lot of liquid. The liquid got all over the sleeve of my tux, too. The lady woke up fairly quickly, before the paramedics arrived. She wasn't very happy with me, and the paramedics didn't really believe what had occurred, until several people sitting right there spoke up. They took her out the back, and since she was near the back, most of the audience never knew what happened.
After intermission, my little chorus sang better than usual, while they were laughing at me in my ugly stained tuxedo. One of my members happened to be an ER doc, and we shared many laughs about it afterwards.
