When performing chest compressions on a child proper hand placement is even more crucial than with
adults. Using two fingers locate the victim's sternum at the bottom of the rib cage where the lower ribs meet, and then
put the heel of your other hand directly on top of your fingers (Figure 1) - use only the heel of one hand to perform compressions.
A child's smaller and more fragile body requires less pressure. The depth of
compressions for a child is about 2 inches. If you feel or hear slight cracking sound,
you may be pressing too hard and may need to apply less pressure as you continue.
