Baby, It's Cold Outside - S7-E9
Factual error: As Hawkeye performs CPR on the hypothermic soldier, he pumps his arms from his ellbows. CPR is done by keeping the arms stiff and pumping with the whole upper body. Hawkeye as a surgeon would know that. Fun Fact: You can perform CPR one-handed in a pinch, but only as long as you keep your arms stiff.
Suggested correction: True, but doing CPR the real way is going to likely seriously injure the actor it is being performed upon.

Chest compressions can definitely be performed by pumping from the elbow, one or two handed. The first documented use was in 1891, so Hawkeye would be aware of it. However, modern CPR standards, including straight arm procedures, were not developed until at least 1960 by the American Heart Association. Using straight arms and bending at the hips uses the larger muscle groups of the core and legs, which provides more control, as well as stamina. This is not an error for the Korean War era.
Additionally, what Lorg said - you don't want to hurt the actor, you can see his shoulders rise as his arms straighten, giving the illusion of compressions. There is another episode where Hawkeye is performing chest compressions similarly, and yells at the unconscious patient that his arms are getting tired, which is what would happen with bent elbow compressions, and one of the reasons modern technique uses straight arms.
I didn't know that, but it makes sense that CPR procedures would evolve. You should submit that as a direct correction to my mistake.
