Determine if the Victim is Awake
A is for Awake. Is the victim awake, yes or no?
If our victim is not awake, try to wake him. Give him a brisk shake of the shoulders or rub your knuckles on his breastbone and shout something. Anything will work. Try "Hey you!" or "Yo, dude!" or "Go Giants!" It doesn't matter what you say, as long as you say it nice and loud to give him a chance to wake up.
If she is awake, let's talk to her. If the victim can't talk, is she choking? If she is choking, do the Heimlich Maneuver.
If the victim wants an ambulance or wants to go to the hospital, make the call. If she's talking but not making sense and she's confused, call 911 immediately and start thinking about why she might be confused.
