In case of a sudden cardiac arrest, first call your nearest hospital or medical centre for an ambulance to take him or her to hospital on time.
Now, carefully position the effected child on her or his back. Make sure not to move or twist the next, head or spine of the child.
Tap and shout at the child as much as you can in order to get response from him or her.
If no response, continue your CPR until the arrival of an ambulance.
Gradually pinch the child’s nose shut, maintaining an open airway for exchange of oxygen.
Cover the child’s mouth with yours and give him or her at least two long but slow breaths, maintaining a proper seal in between.
If you still did not get any response from the child, position the heel of your right hand on the lower tip of the child’s breastbone, measuring two finger widths towards his or her head.
Place your left hand on the right top of your right hand, properly interlacing the fingers of both hands.
Now, take a position, lean forward over the chest of the child so that the shoulders are over your hand.
Push the chest of the injured child downward with a normal weight and power. Make sure to compress his or her chest for approximately 5 times within 3 seconds.
Remove your hands from his or her chest, again cover the child’s mouth with yours and blow out your breath into his or her mouth until you get a response in form of a chest rise.
If chest does not raise, repeat the five-compression, one-breath cycle for at least 12 times, checking the pulse and breathing time to time.
Continue the CPR until child regains a pulse or the arrival of ambulance and medical staff from your nearest hospital.
