What is the recommended depth of compression when performing CPR on infants?

The recommended depth of compression when performing CPR on infants is indeed 1.5 inches (4 cm). This depth is crucial for effectively compressing the heart to circulate blood during cardiac arrest. Unlike adults, where the guideline suggests a depth of at least 2 inches, infants require a more measured approach due to their smaller chest size and the delicate nature of their developing bodies. Compressing too deeply can cause harm to the infant, including potential injury to the ribs or internal organs. Therefore, the guideline of 1.5 inches strikes a balance between delivering adequate compression to maintain circulation while minimizing the risk of injury.
