What is the correct number of compressions per for a child under 1 year old?

For a child under 1 year old, the recommended number of chest compressions is 30 compressions followed by 2 rescue breaths, delivered at a rate of about 100 to 120 compressions per minute during CPR. If you are using two rescuers, they can switch roles after every 15 compressions and 2 breaths. It's important to use two fingers for compressions, placing them just below the nipple line in the center of the chest. Always ensure that emergency services are contacted immediately in case of a cardiac emergency.
