Infant & Child CPR: Key Differences Every Parent Should Know (AHA Pediatric Guidelines)

Cardiac arrest in children is most often caused by respiratory failure — not a heart problem — which makes the CPR approach fundamentally different from adult cardiac arrest. The American Heart Association provides specific pediatric guidelines that every parent, caregiver, teacher, and babysitter should know. Understanding these differences could save a child's life.

Age classifications matter. The AHA defines an infant as birth to age 1, and a child as age 1 through puberty. Adult CPR guidelines apply once signs of puberty are present. Each age group requires different compression techniques, depths, and hand positions.

For infants (birth to 1 year): Use two fingers (or two thumbs if two rescuers are present) placed on the center of the chest, just below the nipple line. Compress at least one-third the depth of the chest — approximately 1.5 inches. Deliver compressions at a rate of 100 to 120 per minute. After every 30 compressions (single rescuer), give 2 gentle breaths. Cover both the infant's mouth and nose with your mouth when delivering breaths. Each breath should be just enough to make the chest rise — do not over-inflate.

For children (age 1 through puberty): Use one hand (or two hands for larger children) placed on the center of the chest on the lower half of the breastbone. Compress at least one-third the depth of the chest — approximately 2 inches. Maintain the same rate of 100 to 120 compressions per minute. The compression-to-breath ratio is 30:2 for a single rescuer or 15:2 when two trained rescuers are present.

The critical difference: breathing is essential. Unlike adult cardiac arrest where Hands-Only CPR is effective for bystanders, the AHA strongly recommends that CPR for infants and children include rescue breaths. Because pediatric cardiac arrest is usually caused by breathing problems (choking, drowning, asthma, infections), providing ventilation is critical to restoring oxygen levels.

When to start CPR on a child: If the child is unresponsive and not breathing normally, begin CPR immediately. For a lone rescuer with no phone nearby, the AHA recommends performing 2 minutes of CPR before leaving to call 911. This differs from adult guidelines where calling 911 first is the priority, because children are more likely to benefit from immediate oxygenation.

AED use in children: Most modern AEDs come with pediatric pads or a pediatric dose attenuator for children under 8 years old or weighing less than 55 pounds. If pediatric pads are not available, use adult pads — but ensure the pads do not touch or overlap on the child's chest. For infants, place one pad on the chest and one on the back. Our pediatric CPR courses in Tallahassee give parents and caregivers extensive hands-on practice with infant and child mannequins so you build the muscle memory needed to respond effectively under pressure.
