*Tap the victim or call his name if known, to find out if he is conscious or not.
*If he is unconscious, look at his chest and place your ear close to his heart to check if he is still breathing.
*If the above are negative, immediately shout for help
*Call the local emergency number, or immediately start arrangements to transfer the victim to the nearest health center.
*Put the person on his back and kneel next to his neck and shoulders.
*Place the heel of one hand over the center of the person’s chest, between the nipples.
*Place your other hand on top of the first hand.
*Keep your elbows straight and position your shoulders directly above your hands.
*Use your upper body weight (not just your arms) as you push (compress) about 5cm deep.
*Push hard at a rate of about 100 compressions a minute.
*If you haven’t been trained in CPR, continue chest compressions until there are signs of movement or until a trained medical personnel takes over.
*If you have been trained in CPR, go on to checking the airway and perform rescue breathing (kiss of life).
*1 breath should be given for every 30 chest compressions.
*In children, same procedure should be followed except that only one hand should be used for chest compression (only two fingers in babies) and 1 breath is given for every 15 chest compressions. This is to prevent rib fractures.
