If you receive a life-threatening injury, does 
maintaining consciousness as people rush to get aid 
really help?

You often see in the movies someone saying "stay with me buddy!" or hear about non-movie situations where people say the same: "don't fall asleep," or "keep looking at me" because if they don't, they may die.

Why is it that staying conscious should help you stay alive? What's going on in the body? Can the conscious brain, through some sort of exertion of will, give commands to your body that keep it from shutting down, that it couldn't otherwise give when you are unconscious?

Another reason why they prefer a person stay awake is to get any vital information that may be required. An unconscious person will have a harder time explaining where it hurts than someone who is awake. Sometimes they may also need to identify a poisonous creature that may have injected venom in them.
