The recommended compression depth for infant CPR is at least one third of the chest depth, approximately 1 ½ inches. This guideline is essential because an infant's chest is relatively small and delicate, so compressions must be both effective and appropriate for their size. When performing chest compressions, aiming for this depth allows for sufficient blood flow to the vital organs while minimizing the risk of injury to the chest wall. This standard is based on research that indicates compressions of this depth are effective in generating adequate blood pressure during resuscitation efforts without causing harm to the infant's developing body. Committing to these guidelines ensures that the rescuer can provide the best possible care in a cardiac emergency.
