Outline the processes involved in doing CPR in an emergency situation

Explanation:

1  Check the scene and the person. Make sure the scene is safe, then tap the person on the shoulder to ensure that the person needs help.

2  Call  for assistance. If it's evident that the person needs help, call ambulance  then send someone to get an AED.

3 Open the airway. With the person lying on his or her back, tilt the head back slightly to lift the chin.

4  Check for breathing. Listen carefully, for no more than 10 seconds, for sounds of breathing. (Occasional gasping sounds do not equate to breathing.) If there is no breathing begin CPR.
