Use the head tilt chin lift
best method of opening the airway of an unresponsive victim when you do not suspect cervical spine injury
(The nasopharyngeal airway device is another method to insure the airway is open.) Grasp the angles of the victim's lower jaw and lift with both hands, one on each side, displacing the jaw forward and up. Your elbows should rest on the surface where the victim is lying. If the lips close, the lower lip can be opened with your thumb. If mouth-to-mouth is necessary, close the nostrils by placing your cheek against them. The victims head should be carefully supported without tilting it backwards or turning it from side to side. If this is unsuccessful, the head should be tilted back very slightly. The jaw-thrust is the safest approach to opening the airway of a victim who has a possible neck injury because it can be accomplished without extending the neck.

Place elbows on the same ground as the victim's head.
A nasopharyngeal airway is used when you don't want to intubate the victim. Sometimes all you need is that open airway.
What is your question?
The victim would be unable to speak, or sing opera.
It will first advise that it will analyze (in which case nobody should touch the patient). Next, it will advise if a shock is or isn't required.
