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 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: 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: 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: 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: 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 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: 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: 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.
