In the section re: First Aid for Cardiac Arrest for Baby, the rescuer is
placing two fingers on the middle of the chest to do 30 compressions.
In the section re: Two-Rescuer CPR for a Baby, one rescuer is to
encircle the baby's chest with both hands, spread fingers around baby's
back, and place thumbs on the lower half of the baby's breathbone.
Why is the thumb method being used instead of the method used for
the Cardiac Arrest situation?
