PALS Instructor Practice Test 2025 – Comprehensive All-in-One Guide to Master Pediatric Advanced Life Support

The recommended compression depth for chest compressions in infants is at least 1.5 inches (4 cm). This guideline is established to ensure that compressions are effective in generating adequate blood flow during a cardiac arrest scenario. The depth is critical because compressions that are too shallow might not adequately compress the heart, leading to insufficient circulation and oxygenation of vital organs.

This depth is specifically tailored for infants, considering their smaller thoracic cavity and the anatomical differences compared to older children and adults. The goal of compressions is to achieve a depth that allows for optimal heart function while avoiding potential injury to the fragile ribcage of an infant.

Following this standard enhances the chances of successful resuscitation by promoting effective blood circulation during cardiopulmonary resuscitation (CPR). In PALS training, it is emphasized that rescuers should also ensure the chest fully recoils between compressions, which is important for re-establishing blood flow back to the heart and thereby improving overall outcomes.
