Change Day - S6-E8
Continuity mistake: From the back, while denying Charles entry, the whistle Klinger has on flips over his left shoulder. A moment later, as Hawkeye and BJ walk up, the whistle is in front.
Dear Sigmund - S5-E7
Visible crew/equipment: As Potter is panning with the binoculars, you can see the lights, camera and crew reflected in the lens.
Hot Lips and Empty Arms - S2-E14
Other mistake: While trying to sober Margaret up, you can see Trapper's clothing wet in spots where she hung on to him in previous takes.
Continuity mistake: In Henry's office, Burns tosses the stapler toward Radar, and it flips midair. When it falls Ito the file Radar has, it flies level, that is, not twisting in the air.
Continuity mistake: As Hawkeye and Trapper leave the Swamp to watch 5 O'Clock Charlie, Hawkeye is carrying a folding chair, and Trapper has the thermos and glasses. At the show, they both have folding chairs.
Continuity mistake: As Charles talks to Finch, he hangs up the clipboard, and puts the pencil in his pocket. Then as he turns Finch to walk out, he puts the pencil in his pocket again.
Character mistake: Aggie says she was there when Silly Putty hit the market in 1949. It hit stores in 1950.
Audio problem: As Radar sets the clock back to 4:30, you hear ticking. The clock is electric, and wouldn't make a noise like that.
Continuity mistake: As Radar turns from Henry's desk, the tote board he has under his arm disappears as he approaches the file cabinet.
Continuity mistake: Casey's glasses go from dark framed to metal framed and back as he says goodbye to Hawkeye.
Love Story - S1-E14
Continuity mistake: When Trapper puts on the "Dear John" recording, the record is moving at two different speeds in the close up and wide shots.
Continuity mistake: As Potter says "knowing mademoiselles in the war, P.M." (pre Mildred) his hands are by his drink. As he finishes his line, they're crossed on the table.
The Tooth Shall Set You Free - S10-E14
Continuity mistake: As Potter tells Charles about the bad tooth getting worse, Charles' right hand is just above his tray. When the camera is looking at Charles a second later, his hand is chest high.
April Fools - S8-E25
Continuity mistake: As Potter asks Hawkeye about stopping the jokes, his hand is up by Hawkeye's shoulder. After the angle changes, his hand is around waist height.
Hot Lips and Empty Arms - S2-E14
Continuity mistake: In Henry's office, Margaret has pins in her hair over her ears. When she comes out to see Henry, the pins are gone.
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.
Audio problem: After Potter convinces Saunders he still wants to live, the hiss from the anesthesia machine fades out even while Potter and Saunders are still standing next to it. Neither Potter nor Saunders turned off the valve again.
Revealing mistake: Klinger makes a big show of removing a big nut from the Jeep's leaf spring. The nut is clean and shiny whereas the rest of the undercarriage is painted and dirty. If you look closely, there are no screw threads where he takes it off either, there's another hex under it. The simple reason for this is that that nut doesn't belong there and never was affixed, Jamie Farr just pretended it was.
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.
