Continuity mistake: Luka is in talking to the first possible kidney transplant patient - he puts his pen into his pocket and is holding the chart in his other hand, also up by his chest. As he says "Minneapolis", the shot changes and we see him put his pen in his pocket again and his chart is down by his waist - there was no time for the shift.
Continuity mistake: Mark and Dave are talking about the parachutist who had just died. As Dave says, "He died before I had a chance", an extra walks by them on the right. The shot shifts to Mark, who replies, but it is 4 seconds before the extra appears again beside Mark - this should have happened in a split second, not 4.
Continuity mistake: When the shooter in the ER drops his gun, it falls in front of his foot. Just as the shot changes, however, the gun is to the right of his foot (without him moving) and his foot pushes it aside as he runs away.
Continuity mistake: Near the end of the show, Mark is talking to his father, who is putting his bathrobe on; he has one arm in the sleeve but as Mark says, "I need to talk to you", his father turns towards him and the bathrobe is nowhere to be seen - a couple of seconds later he starts to put it on again.
Continuity mistake: Near the beginning of the show, when Elizabeth and her mother are having tea before they both go off to work, for a couple of shots from in front of her, Elizabeth is holding the mug with both hands, but the shots from behind her show her holding it with one hand only.
Continuity mistake: Peter is at his sister's house, in the kitchen, and they are talking about Carla. Jackie takes the dish towel off her shoulder and drapes it over a chair back and heads for the fridge. When the shot changes to her standing at the fridge, the towel is over her shoulder again. In the next shot, it's gone again.
Continuity mistake: Near the start of the show, Dr. Dave asks the patient Jesse how he's feeling and Jesse answers, "Not so well", and then begins throwing up. By the next shot, though, there is more vomit on his shirt than could have possibly got there in such a short time.
Continuity mistake: When Romano is operating on the heart patient Valerie, Lucy has an instrument inside the patient. The shot then changes so that we can see her face and as she says, "Dr. Romano," there is no longer anything in her hand and she is holding it up waiting for a nurse to pass her an instrument, which she takes, but then the shot goes behind her - she now has a different instrument in her hand, which is in a different position.
Continuity mistake: When Mark and Elizabeth are coming round the corner to enter the hospital, Mark says, "Remind me again why you invited her to stay with you", and he has one arm around her and in the other hand he's holding a newspaper. As the shot changes when they go round the corner, his arm is no longer around her and both hands are on the newspaper. There was no time for the switch.
Continuity mistake: When Dr. Lawrence is working on the ER with Mark, he gets frustrated because the tag Kerry's issued to everyone gets in his way. He asks someone to get it out of his way, and as he moves around to the other side of the table, we can see it has been pulled up around the back of his neck. As he reaches the other side, it is suddenly hanging straight down again. A short time later it is tucked up around his neck again. At no time did he adjust it.
Continuity mistake: When Dr. Lawrence is tending to the patient with the stabbed wrist, the blood splatter on his lapel goes from bright red to brownish and back to red within a few shots.
Continuity mistake: After Carter pulls the IV out of the patient who was allergic to sulfa, Malik asks, "Where's all the blood coming from?" and we see the patient's arm outstretched, bleeding from where the IV was. Carter says, "She must have pulled the IV out", and we see her arm folded up over her stomach - there was no time for the change in position.
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: When Mr. Perez pushes Carter into the window, Carter's stethoscope is around his neck with the earpieces on the right. At one point during the fight the stethoscope is around his neck with the earpieces on the left - and then returns to the other position.
Continuity mistake: At the beginning of the show, Randi is talking to Dr. Lawrence and is holding her neck tag on its lanyard in front of her, but as she says "Malik" and the camera shot changes, suddenly her left hand is on her waist.
Continuity mistake: When Carter goes into the lounge, he leans his crutches against the lockers and then moves his bag off his shoulder. One crutch falls to the floor, then the bag, then the other crutch. When the shot changes to show these items on the floor, the bag is lying neatly on top of the crutches - an impossibility due to the way they all fell.
