How deep should chest compressions be for an infant?

The appropriate depth for chest compressions in an infant is about 1½ inches. This depth is essential because it allows for effective compression of the heart, ensuring that blood is circulated adequately to vital organs during a cardiac arrest situation.

In infants, approximately one and a half inches (approximately 4 centimeters) corresponds to about one-third the depth of the infant's chest, which is the recommended compression depth. This depth is crucial for creating enough pressure to circulate blood while also minimizing the risk of injury to the chest or internal organs.

While deeper compressions might seem beneficial for maximizing blood flow, compressing too deeply can potentially cause harm, particularly in infants with their more fragile rib cages and softer tissues. Maintaining the correct depth ensures that resuscitation efforts are both effective and safe.
