Continuity mistake: When the paramedics and the rest of the firemen gather round the failed pacemaker patient, their positions change and in DeSoto's close-ups the Captain isn't seen (for the camera angle's sake), although in other shots he's right beside Gage. As an aside, note when Captain Stanley first first gets off the engine and trips in the background.
Continuity mistake: When DeSoto and Gage are in the pool with the little girl whose arm is stuck in the drain, their shoes and pants are soaked. However, just after Gage gets off the Biophone, his shoes and pants are completely dry, and then when the pool has been mostly drained both DeSoto and Gage are dry.
Revealing mistake: In episode 2x5, "Peace Pipe", when Brackett gets on the line with Johnny, who's at the scene of the drunk driver's accident, Brackett presses two buttons - the third and fifth, to record the conversation on the tape machine. However, in this episode when Dixie gets on the line with Johnny, while he's with the little girl whose arm is stuck in the pool drain, Dixie presses only one button - the second, to record the conversation.
Continuity mistake: When Johnny and Roy are standing by the squad outside Rampart, talking about the man in a hepatic coma, both ER doors are wide open, but when the woman drives up and then shouts that she needs help both doors are closed, and this continues a few times depending on the angle of the shot.
