Tongue
The most common cause of airway occlusion (airway obstruction) is choking on foreign objects. This means swallowing an obstructive object or having something lodged in your trachea causing the airway to lose its patency.
tongue
Often it is a food item that has blocked the airway. Trying to swallow too much at one time may cause an airway obstruction. People have died by their own vomit, usually when under the influence of alcohol or drugs. Babies and young children may choke on small toys, as young children and babies frequently put toys, etc, into their mouths.
The most common cause of airway obstruction in any patient - supine or not - is the tongue. This is why the first maneuver that should be performed on a patient not breathing is the head-tilt/chin-lift or the jaw thrust. This is to help clear the tongue from the airway and may allow the person to breathe again.
