ELI5: Is it really important to human in critical condition to stay conscious, and why?

In many action movies we see how paramedics etc. prevent injured person from loosing consciousness, like "Stay with us!" 
Is it true? Does this improve the prognosis? Why?

No, it doesn't help them live. But what it can do is identify health threats which would otherwise be difficult to detect. Someone who has hit their head needs to remain awake because a brain bleed needs immediate attention and is basically undetectable if the victim is asleep. If they are awake you could notice them becoming incoherent and falling unconscious.

In movies allowing your actors to fall asleep in a scene is generally bad for the movie because there is a really limited range of acting they can perform while miming unconsciousness.
