Continuity mistake: While Early is examining Johnny in the ER, telling Roy about symptoms for ruptured liver or spleen, in the closeup Roy's holding up the IV bag with his right hand, but next wide shot it's held up in Roy's left hand.
Continuity mistake: During this episode Brackett is wearing a tie with white, light blue, and dark blue broad stripes, which should be tied in an identical manner in consecutive shots, but it's not. One example is when Brackett examines the tree surgeon, but when he waits in the hall with Morton and Dixie while Malcolm takes x-rays, Brackett's tie is tied differently, and when he walks back into the room the tie reverts back.

And when they're all dispatched, the timeout is 14:15.
Continuity mistake: When Karen asks Roy and John for an evaluation of that morning's run, a coffee cup suddenly appears near her arm, which promptly disappears, until Roy soon places his coffee cup near her arm when he sits down beside Karen.
Pressure 165 - S5-E7
Continuity mistake: After Johnny discovers that the white stuff he left cooking on the stove has turned green, Station 51 is dispatched to the structure fire, so everyone rolls on the call. When Johnny and Roy return, and Johnny decides to dump all the food he cooked, a large stock pot has mysteriously and conveniently appeared on the counter, where it did not exist when they left.
Above and Beyond... Nearly - S5-E20
Revealing mistake: Dixie and Brackett rush onto the elevator with a crash cart to go up to the third floor, for a possible MI in the dental clinic. The camera's POV is from the elevator, and in one continuous shot, without cutting away, we see the ER hallway through the open doors, then the doors close and in a few moments the doors open on the third floor. Even though the set has changed a bit, we can tell it's still the ER hallway by things such as the same scuff marks on the floor, and we can also catch a glimpse of the paramedic status board on the wall, where the base station room is located.

The Girl on the Balance Beam - S5-E18

The Girl on the Balance Beam - S5-E18
Continuity mistake: When Johnny and Roy are at the movie studio, while they're dangling from their lifelines they're trying to help the actress dangling from her own lines, but when she freaks out she drops her wand (yes, a wand) in the wide shot, but next closeup she's still holding it.
Visible crew/equipment: After Station 51 is dispatched to the landslide, when Mike pulls the engine over on the side of the street, as Captain Stanley and Chet walk past the front of the engine, the cameraman's and crew member's legs are reflected on the windshield.
Continuity mistake: When Mr. And Mrs. Merkle visit the station the first time, Mrs. Merkle's long, pointed blouse collar jumps under and over her sweater repeatedly.

Continuity mistake: When Marco and Chet use the jaws to lift the car off the victim, Roy begins to get her vitals, then it cuts to Captain Stanley on the Biophone saying, "Vitals second victim, pulse is 120, respiration's 30, she's pale and clammy," but it's not until quite a few shots later that Roy actually shouts those vitals to Captain Stanley.
Character mistake: At the restaurant, when Captain Stanley's on the Biophone with Rampart, Brackett asks, "Is there any evidence of external hemorrhaging on your second victim?" and then Cap responds, "We can only see superficial cuts at this time... Pupils are equal and reactive, negative on the IV at this time," as if Brackett ordered an IV, but Brackett never said anything to Squad 51 about any IV.
