NOTE: This ratio is the same for one-person & two-person CPR.
In two-person CPR the person pumping the chest stops while the other gives mouth-to-mouth breathing.
CPR for Children (Ages 1-8)
CPR for children is similar to performing Quick CPR for adults. There are, however, 4 differences.
1) If you are alone with the child give one minute of CPR before calling 911
2) Use the heel of one hand for chest compressions
3) Press the sternum down 1 to 1.5 inches
4) Give 2 full breath followed by 30 chest compressions
