CPR for children is similar to CPR for adults.
The compression to ventilation ratio is 30:2. If you are alone with the child give 2 minutes of CPR before calling 911.
1) Use the heel of one or two hands for chest compression
2) Press the sternum approximately one-third the depth of the chest (about 2 inches) at the rate of least 100/minute
3) Tilt the head back and listen for breathing. If not breathing normally, pinch nose and cover the mouth with yours and blow until you see the chest rise. Give 2 breaths. Each breath should take 1 second.
CONTINUE WITH 30 PUMPS AND 2 BREATHS UNTIL HELP ARRIVES
