Airway Obstruction:

1. Call out to the victim in question and tell them your name and ask for permission to treat them. If they are unconscious go ahead and treat them.
   
2. At an arm's distance, shake the victim by touching the shoulder and shout, "can you hear me?" If there is no answer place the palm of one hand on the forehead and one on the abdomen turn your face towards their feet and lower your head down close to their nose and mouth. Look to see if you see their chest rise, feel to see if there is any movement in the abdominal area, and listen for any air movement.
   
3. If there is no sign of breathing, keep your hand on their forehead and place two fingers from the other on under the chin and tilt the jaw upward while tilting the head back slightly. As before look, listen and feel.
4. If there is no air exchange check to see if there is a visible obstruction in the mouth or throat that can be removed easily. (If yes remove and repeat step 3 and look, listen and feel.)
5. If there is still no air exchange noticeable, begin CPR. Remember you cannot stop until someone else arrives to take your place.
