How CPR Works
"B" is for BREATHING. Cover the infant's mouth and nose with your mouth creating a seal, and give a quick, gentle puff from your cheeks.
Let the victim exhale on his own - watch his chest and listen and feel for breathing. If he does not breathe on his own, again place your mouth over his mouth and nose and give another small puff (Figure 1).
If the infant remains unresponsive (no crying or moving), immediately check his circulation
