If you arrive on the scene: Check the scene for safety.
1. Check the victim for consciousness. Gently tap the shoulder or flick the bottom of the heel and shout.
2. Call 911.
3. If the infant is lying on his stomach, turn him over onto his back. Check for Breathing and a Pulse:
a. Tilt the infant's head back, slightly, using the palm of one hand on the forehead. At the same time, lift up on the infant's chin with two fingers of your other hand. Put your ear close to the infant's nose and mouth and watch his chest for any movement. Look, listen and feel for breathing.
b. With two fingers, feel for a pulse on the inside of the baby's upper arm. At the same time, look for signs of life and breathing for 10 seconds.
Keep the head tilted back. Place your mouth over the baby's nose and mouth. Give 2 slow, gentle breaths -- just enough to see the baby's chest rise.
Pulse But No Breathing
Begin Rescue Breathing:
a. Tilt the head back. Lift the chin. Place your mouth over the baby's mouth and nose. Give one slow, gentle breath every 3 seconds (count 1-1000, 2-1000, breathe. etc.).
b. Recheck for signs of life every 2 minutes or 40 breathes.
No Pulse, No Breathing
a. Position 2 or 3 fingers on the center of the breastbone, just below the nipple line. Keep your upper hand on the forehead to maintain an open airway.
b. Compress the chest 1½ inches in depth 30 times. Give 2 breathes (continue with 30 compressions/2 breathes, 30 compressions/2 breathes, etc.).
Continue CPR until another rescuer takes over, you see signs of life or help arrives. If you witness a sudden collapse, call 911. No pulse, no breathing, begin CPR.
