Do You See What I See? - S4-E10
Continuity mistake: Even though Carter and Henry were outside in the snow when the patient Lenny arrived, and they had quite a bit of snow in their hair, when the shot goes to them entering the building, we don't see any snow on Carter and Henry - but there is still lots on the patient and the paramedics.
Continuity mistake: Carter, referring to the patient Isadore, announces that he can't find a pulse in his leg - as he says this, his stethoscope is around his neck. Doug orders him to find a surgeon and suddenly the stethoscope is in Carter's ears, but there was no time for the switch.
Last Rites - S6-E2
Continuity mistake: Carol puts a chart on the counter and says, "I need 2 mgs of morphine for Mrs. Bragha", and Doctor Dave signs, with both arms on the counter when the camera is on Carol. But when the camera is on him, he has has one hand on the counter and one arm down by his side. This happens for a few shots.

Continuity mistake: Lizzie sees Dr. Morgenstern for the first time in the ER and she asks Kerry, "Who the hell was that?", and Kerry answers, "Our Chief of Emergency Medicine." Yet when he resigns in Episode 19, he tells Peter he's resigning as Chief of Surgery. Unless he held both positions, Kerry's answer could not be considered a character mistake, as she would have known what his position was.
Continuity mistake: Carters throws his white towel on top of the lockers and it falls to the floor and the locker door closes - but the next shot shows the towel on top of the lockers again and the locker is half-open.

Continuity mistake: Near the start of the show, Susan rushes into the ER with Chloe who is in labour. Carter is sitting behind the desk and he tips back, falls over, and takes his coffee down with him. Then he is suddenly standing there with a wheelchair for Chloe and he also hands Susan a mug of coffee from the counter, which somehow just appeared there. All this took place in 6 seconds, which couldn't have happened in real time.
Night Shift - S3-E11
Continuity mistake: When Carter and Doyle are running down a corridor to the patient having a heart attack, the camera follows them along the floor and you can see several coloured lines going down the hall.
