Who taught you? The compression rate for Infant CPR, single rescuer, is 30 compressions, then 2 breaths. If you have 2 rescuers, its 15 compressions, then 2 breaths.
Place 2 fingers on the breastbone -- just below the nipples. Make sure not to press at the very end of the breastbone.
Keep your other hand on the infant's forehead, keeping the head tilted back.
Press down on the infant's chest so that it compresses about 1/3 to 1/2 the depth of the chest.
Give 30 chest compressions. Each time, let the chest rise completely. These compressions should be FAST and hard with no pausing. Count the 30 compressions aloud. Then give 2 rescue breaths. Each breath should take about a second and make the chest rise.
