Continuity mistake: As Mark futilely pounds on Jodi O'Brien's chest, Carol can be seen in the background, removing her protective glasses with one hand. However, after the time of death has been called and they're showing the reactions of everyone present in the room (Susan, Carol, Carter, Lydia, Chen), Carol is seen taking the glasses off again, this time with both hands.
Continuity mistake: Peter goes into the operating room, demanding to help with his mother's surgery. When he goes in, his cap is pulled down over his hair, but when he is talking to the surgeon in charge, about an inch of his hair shows for a couple of shots. The surgeon orders him out, and he leaves, and his hair is completely covered again. At no time did he adjust the cap.
Continuity mistake: Doug and Peter are running to meet the ambulance transporting the boy with the crushed leg. From the back we see Doug with his arms out as he runs, but the shot changes to the front and he has his hands in his pockets, with no time to change naturally.
Continuity mistake: When Morris is on the bed following his shock there are three point of view (POV) shots. Morris on the bed, Morris's POV of the medical staff hovering over him and a shot from behind the staff looking down on Morris. The placement of characters is misaligned between views, most notably when the shot is from behind the staff looking down: there is a sizable gap between the two on the left and right, where as from Morris's POV they are clustered close together with no gaps between the staff members.
Continuity mistake: As Doug Ross sits with the little girl Kaneisha who is sleeping, her bedcovers change position noticeably in one shot, and then back to the way they were in the next. In the same shots, Doug's ID also changes from being completely noticeable to almost completely obscured, and then back again.
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: Carol and Carter are in the room with the patient Tatiana and the dog; Tatiana has a yellow marker in her hand. In some shots she appears to be hugging the dog and in others drawing something with the marker, with no time to change positions.
Continuity mistake: In "Graduation Day", towards the end when Abby and her mother are in the apartment talking about her leaving, Abby is holding the baby and when the camera is facing her the baby is up on her shoulder. But when the camera is to her back facing her mother the baby is down. It continues like that through the whole scene.
Continuity mistake: Abbie is asking Peter and Carter questions about infant developmental stages and they are standing up straight next to the crib. When she says "don't worry, Dr. Benton", the shot shows Peter with one elbow draped over the crib and Carter is leaning over with arms folded. They could not have changed so quickly in real time.
Continuity mistake: Molly's mother walks away from her daughter's bed and towards her ex-husband and has moved about a foot from the bed; the next shot goes back to Molly's face and we can see her mother's hand still on her shoulder, even though this would be physically impossible.
