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 This is very outdated as in 2010 the American Heart Association changed the recommendation to CAB for Compressions, Airway, Breathing following evidence that compressions first in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.
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.
