Continuity mistake: Carol is seen walking into the ER twice at the beginning of the episode.

Continuity mistake: While Mookie stands at the doorway of Trauma 1, where the patient's traumatic amputation is being treated, Lydia gets splattered with the man's blood and says, "Whoa! I got a pumper," but in the next shot that blood has suddenly vanished from her face and safety glasses.
Visible crew/equipment: Susan searches for a surgeon for Mr. Bozinsky's aortic aneurysm. When Bozinsky has coded, Bob cuts the man open, then does the cross-clamp procedure herself, and in a couple of Wendy's close-ups, the reflection of the boom microphone is visible on her safety glasses.
Audio problem: While Susan is with Mr. Bozinsky, Lydia takes Mrs. Bozinsky to the payphone. Then, when we hear Susan say, "Mr. Bozinsky, are you sure when I push here, this isn't hurting you?" Susan's mouth is not actually saying anything.
Visible crew/equipment: After Jerry shows Mark how to use the paging microphone at the admit desk, the camera dollies out just as everyone joins Mark for Carter's prank, and there's a director's chair, with a crew member (has a goatee/beard) standing behind it, that is visible at the left side of the screen.
Visible crew/equipment: While Jerry is watching TV news about the snowstorm, Mark asks him how the desktop paging microphone works. Then, as Jerry walks toward Mark, the reflection of the boom operator moving with the boom mic is visible on the glass partition.
