What adjustments are made for infant CPR (under 1 year)?

For infants under 1 year, using 2 fingers for compressions is the correct technique. This method is appropriate because it provides enough force to circulate blood effectively while minimizing the risk of excessive pressure on the infant's small chest. The 2-finger technique allows for precise control and reduces the likelihood of causing injury to delicate structures in the infant's chest.

Infants have a much smaller thoracic cavity compared to adults, so using a single finger may not generate adequate compressive force to maintain circulation. On the other hand, using a whole hand or both hands can apply too much pressure and lead to injuries, such as fractured ribs or damage to internal organs, which are particularly fragile in infants. Proper CPR technique is crucial for effectively managing cardiac arrest in this vulnerable age group.
