"B" is for BREATHING. If the child remains unresponsive and still not breathing on his own,
pinch his nose with your fingertips or cover his mouth and nose with your mouth creating
a tight seal, and give two breaths (Figure 1).
Keep in mind that children's lungs have much smaller capacity than those of adults. When ventilating a
child, be sure to use shallower breaths and keep an eye on the victim's chest to prevent stomach distention.
