1. Check whether infant is alert by tapping the infant gently on the shoulders, observe for movement or noise / cry.
2. If the infant doesn't respond, call for help. Do not leave the infant to go call for help unless you have performed Cardio Pulmonary Resuscitation (CPR) on the infant for atleast 2 minutes.
3. Carefully place the infant on their back taking care not to twist the head / neck
4.Open the infants airway by lifting up the chin with one finger and at the same time tilting the head by pushing down the forehead with your other hand
5. Look for signs of breathing by observing if the chest rises, listen for signs of breathing by placing your ear close to the infants mouth and feel for breaths on your cheek by drawing your side of the face near the infants nostrils.
6. If the infant is not breathing, deliver 5 rescue breaths using your mouth. To do this, cover the infant's mouth and nose tightly with your mouth. Each breath should take about a second and should make the chest rise.
7. Feel for a pulse, if in an older child it can be felt on the neck and if younger at the elbow joint. If it is absent you should then perform chest compressions by placing 2 fingers on the breast bone just below the nipples such that you are pressing at the very end of the breast bone. Keep your other hand holding the infants forehead and holding the head tilted back.
8. To deliver the compressions, you need to press down the infants chest so that it compresses about 1/3 to 1/2 of the chest. You should deliver 15 chest compressions, each time letting the chest rise completely and the compressions should be fast and with no pausing
9. After 15 compressions, give the infant 2 more breaths making sure that the chest rises.
10. Continue CPR by delivering a cycle of 15 chest compressions followed by 2 breaths, for 2 minutes.
11. After about 2 minutes of CPR, if the infant still does not have normal breathing, coughing, or any movement, leave the infant if you are alone and call for help.
12. Repeat rescue breathing and chest compressions until the infant recovers or help arrives.
13. If the infant starts breathing again, place him or her in the recovery position. Periodically re-check for breathing until help arrives.
