First rescue, use of EKG and strip transmission inconsistent with previous episodes. (1) When Squad 51 arrived at scene, victim already was patched in. Even if the engine had the patches, the distinct beeping of the EKG was heard. (2) When Johnny used the land line, he connected the EKG through the land line with the phone patch. Then once the patch was secured on the phone, Johnny went to the biophone to continue talking with hospital. Why go through the land line with EKG... they could have just sent it through the telemetry unit.
Additional gaffe - When Squad was dispatched on first run "in place of Squad 39", they turned left out of the station. Later, when there were "called up to Station 39", they turned right out of the station.
