Character mistake: The firefighters state that the acronym for CPR is ABC for Airway, Breathing, Circulation. This is very outdated as in 2010 the American Heart Association changed the recommendation to CAB for Compressions, Airway, Breathing following evidence that compressions first in CPR saves more lives.
Nothing Seems the Same - S4-E1
Factual error: Nothing Seems the Same: The bus has Seattle Department of Corrections printed on the side. There is no Seattle Department of Corrections. Corrections in Seattle are done by King County Jail or Washington State Department of Corrections. (00:05:07)
Factual error: Jack should not have a beard. Firefighters are not allowed to have beards because it interferes with the SCBA seal.
Continuity mistake: The man who has fallen down the ravine raises his hand as he shouts for the EMTs. The scene immediately cuts to a shot of him holding his wound with his hand down.
Other mistake: The Seattle Police officer's badge states Seattle Police, but the patch on his jacket states Metropolitan Police. (01:15:00)
Factual error: The Seattle Police officer's uniform for the City of Seattle is not correct. Seattle Police don't wear light blue shirts anymore. The Seattle Police uniform is dark blue (shirts and pants) and the department has a redesigned patch. (01:15:00)
