Yes. When treating a baby, always start with CPR chest compressions. Push down on the center of the chest at a depth of about 1.5 inches, or ⅓ the depth of the chest. Set the defibrillator to its pediatric setting, or attach the pediatric pads. If no pediatric pads are available, you can use adult pads. Just make sure that the pads don’t touch one another. One pad should be placed on the center of the baby’s chest, and the other on the center of the baby’s back.
