A person injured in a traffic accident is unconscious and shows signs of asphyxia. What must be done first?

Question

DentroTest · Accepted Answer

In an unconscious person the tongue falls backward and can obstruct the airway and prevent breathing. The head-tilt/chin-lift maneuver (one hand on the forehead gently tilts the head back and the other lifts the chin) lifts the tongue and lets air pass, so it is the first thing that must be done. Placing the injured person in the anti-shock position (lying down with the legs raised) does not open the airway and does not resolve the asphyxia. Sitting them up or putting them in a semi-seated position does not either: the airway is not opened and an unconscious person does not stay seated.
