"Cardio pulmonary resuscitation(CPR) can be lifesaving, but it is best performed by those who have been trained in an accredited CPR course.
The following steps are based on instructions from the American Heart Association:

1. Check whether the child is alert by shaking or tapping the child gently on the shoulders. If the child moves or makes some noise ask them 'are you OK? '.
2. If the child does not respond shout for help. If no one else is available Do not leave the child to go call for help until you have performed CPR for atleast 2 minutes.
3. With care, place the child on his/her back. If spinal injury is suspected 2 people should carefully move the child to prevent the head/neck from twisting.
4. Open the child's airway by lifting the chin with two fingers of one hand and with the other hand tilting the head by pushing down on the forehead.
5. Listen for breathing by placing your ear next to the child's nostrils, watch the chest to see if there is any movement, and feel for breath on your cheek.
6. If the child is not breathing, place your mouth on top of the child's mouth in a way that it tightly covers it, then pinch the child's nose closed. Keep the held tilted and the chin lifted then give 5 rescue breaths with each breath taking about a second and producing a visible chest rise.
7. Feel for a pulse. If none felt, deliver chest compressions, place the heel of one of your hands on the breast bone, just below the nipples making sure that the heel is not at the very end of the breastbone.
8. Keep your other hand on the child's forehead - tilting the head backwards.
9. Deliver 15 chest compressions by pressing down the child's chest so that it compresses about 1/3 to 1/2 of the depth of the chest. The compressions should be hard and fast with no pausing.
10. Give the child 2 more breaths making sure that the chest rises. Continue CPR (15 chest compressions, followed by 2 breaths, then repeat) for about 2 minutes.
11. After about 2 minutes of CPR, if the child still does not have normal breathing, coughing, or any movement, leave the child if you are alone and call for help.
12. Repeat rescue breathing and chest compressions until the child recovers or help arrives.
14. If the child starts breathing again, place him or her in the recovery position. Periodically recheck for breathing until help arrives.".
