MASH was one of the most successful American sitcoms of all time, running for 11 award-winning seasons from 1972-1983. The show is set at an American Mobile Army Surgical Hospital, or MASH, in Korea during the Korean War of the 1950's. Starring Alan Alda as Hawkeye Pierce, an army surgeon who likes to play by his own rules, the show was a massive success, culminating in the most highly-watched series finale of all time, garnering 106 million viewers. That's all interesting history... but how accurate are the medical scenes? Today we look at the ethics of taking someone's blood without their consent, performing a tracheotomy in the field, proper behavior during surgery, how long you could hold a heart together with your fingers, and of course, CHEST COMPRESSIONS.
