Continuity mistake: In the bookmaker's apartment, while Roy. John, Marco and Chet are working on the bookie who's in full cardiac arrest, Vince walks in and speaks to Captain Stanley. Then Vince, who's wearing a watch and ring on his right arm/hand, reaches for all the ringing telephones, and one by one he removes the receivers from the bases, but the right arm/hand in the closeup has no ring or watch.
Continuity mistake: When Roy and Johnny are on the Coast Guard helicopter, responding to The Boat wreck with injuries off Catalina, there are a few interior shots of them that are flipped, while they're looking out the windows. The paramedic patches are on their left sleeves, but in the flipped shots the paramedic patches are on their right sleeves.
Continuity mistake: While 51 is breaking into the bookie's apartment, after Chet uses the axe on certain areas of the door he puts the axe down, and in the shot from inside the apartment Chet reaches in through the hole on the door to undo the chain and remove the bar, but when the door opens there's another new axe mark over the top lock that was not made by Chet.
Continuity mistake: After the bookmaker has had the heart attack, when Captain Stanley bangs on his door, the bookie pulls one of the four telephones onto the floor, and when Roy walks in it ends up lying on the floor between the defibrillator and drug box, leaving three phones on the table. However, in the closeup, when Vince places all the phone receivers onto the bases, there are four phones on the table, plus a notepad suddenly appears on the table, and there are fewer cigarette butts in the ashtray.
Continuity mistake: When the Coast Guard chopper reaches The Boat that ran aground off Catalina, during the rescue Roy and Johnny are seen wearing water-type shoes, not their uniform shoes.
Continuity mistake: When the patients who were treated at 86's arrive at the ER, Dix has Morton take the asthmatic boy with bronchitis into treatment 1. Then, when Roy is with Early in treatment 4, Early tells Roy to go to treatment 1 to ask Morton if he needs help, and when Roy walks into treatment 1 we can see that it's not really treatment 1, it's actually treatment 4 just playing the part of treatment 1.
Continuity mistake: While Roy and Johnny are at 86's treating everyone who is being brought in, when Johnny's on the Biophone with Brackett, in Brackett's closeups at the base station, we can see that the actor has a very swollen upper lip. When the officer who was hit by lightning is brought into the ER, Brackett's lip is much less swelled, and more the way it normally looks, but when Brackett is back at the base station, his upper lip is swelled up once again.
Continuity mistake: When Station 51 is dispatched to 'the man down' at the hotel, Roy gets into the squad fully dressed (he was talking to Chet) and wearing his blue uniform shirt, but when they're in the apartment his shirt is gone and he's only wearing an undershirt under his jacket, though Johnny is wearing his uniform shirt.
Continuity mistake: When the woman from the car accident is in the ER, and goes into V-fib, Brackett, Morton, Roy and Johnny work on her. Johnny does chest compressions and they defib three times, then Morton takes over the chest compressions, but when Brackett is about to defib the fourth time we see Johnny's arms stopping the compressions, when in fact it was Morton doing them at that time.
Continuity mistake: When Roy and Johnny are on their lines attempting to rescue the unconscious game show contestant wannabe, before they're able to get the pompier life belt around the man's waist, the belt falls to the ground and lands near the man's cape and broken balancing pole. However, when the ambulance attendants walk towards the building, in the overhead shot the life belt has vanished; only the cape and broken pole are lying on the ground.
Continuity mistake: When Station 51 is dispatched to the 'man down', time out is 21:30, but when Johnny and Roy are at Mr. Jefferson's apartment, Johnny's watch reads 3:05. Back at the station, when Chet's sitting beside Johnny at the typewriter, Johnny's watch reads 5:15, but at Rampart it's after 2:00 when Mr. Jefferson has the bypass operation. When Station 51 is dispatched to the car accident, time out is 1:50, but when Johnny checks the woman's pupils, his watch reads 1:00, and when they're back at the station his watch reads 10:05, as Johnny tells Roy that the show is crazy.
Continuity mistake: When Dr. Early and Dr. Morton are in the treatment room with Mr. Jefferson, Morton's stethoscope is draped over his shoulder with the ear tubes at his back in the wide shots, but in the closeup the ear tubes are lying in front.
Continuity mistake: When Roy and Johnny are in the apartment, just as Mr. Jefferson mentions that Shorty brought in hot tractors, it cuts to a closeup of Roy who is not wearing a stethoscope, but in the next shot the stethoscope is suddenly around Roy's neck.
Continuity mistake: When the woman from the car accident is in the ER, Brackett tells Morton to intubate her and Morton grabs the laryngoscope and slides her body down on the gurney to a proper position, but in the next shot from another angle Brackett orders the intubation again and the same things are repeated.
Continuity mistake: While the woman from the car accident is in the ER, when Brackett tells Morton to intubate her Morton has a penlight (to check pupillary response) in the pocket of his scrubs, but in the following shots that penlight keeps vanishing from his pocket and reappearing.
Continuity mistake: At the scene of the vehicle accident, once Vince wraps the gauze around the head of the driver of the pickup truck, the same bystanders are standing in two places at once - on the sidewalk beside Engine 51 and across the street beside Squad 51.
Continuity mistake: When Station 51 is dispatched to the 'man trapped between two buildings', Roy is not wearing a watch when he and John head out on the lines between the buildings and also when they get back on the roof, but during the actual rescue while on the lines, both stunt guys are wearing watches on their wrists.
Continuity mistake: When Station 51 is dispatched to 'man down' at Hotel Potter, the address is given as 11876 Fishburn, between MacArthur and West 7th, but when the squad and engine are in front of the building, the corner street signs read Trenton and Parkview.
Continuity mistake: When all the guys enter the apartment with the doctor lying on the couch, John's carrying the Biophone with his right hand and starts to place it down, but then it cuts to another angle and John's holding the Biophone in his left hand as he places it down.
Continuity mistake: After Early tells Dr. Ned that he thinks he has mononucleosis, when Early leaves the room, the nurse that's in the room with Dixie walks away from the patient to the other side of the room, but in Dr. Ned's closeups that nurse is still standing behind him while he talks to Dixie.
