The appropriate depth of chest compressions for infants is about 1.5 inches (4 cm). When performing CPR on infants, it's crucial to ensure that compressions are effective yet gentle enough to prevent injury, as their bodies are much more delicate than those of older children and adults. The guideline specifies that compressions should be delivered at a depth of at least one-third the anterior-posterior diameter of the infant's chest, which typically equates to approximately 1.5 inches. This depth allows for adequate blood circulation to vital organs without risking harm to the infant's ribs or internal organs.

It's also essential to maintain a proper compression rate and allow full recoil between compressions to ensure optimal blood flow. Understanding the correct depth and technique is vital for anyone trained in Basic Life Support to ensure effective resuscitation during a critical emergency.
