What is the minimum chest compression depth for infants during CPR?

• A. 0.5 inches
• B. 1 inch
• C. 2 inches
• D. 1.5 inches

Answer: (D)

Infant chest compressions must be deep enough to push blood out of the heart and circulate it to the rest of the body. The minimum depth is about 1.5 inches (4 cm), which is roughly one-third of the infant’s chest depth. This depth provides enough pressure to generate adequate blood flow without needing excessive force. Shallower compressions, around half an inch to an inch, don’t produce enough blood flow, while pushing much deeper than 1.5 inches increases the risk of chest injury in infants. So, 1.5 inches is the target minimum.
