What is the correct depth of chest compression for an infant?

The correct depth of chest compression for an infant is about 1.5 inches. This depth ensures effective compressions without causing injury to the infant's fragile chest structure. The guideline emphasizes that compressions should be made at a rate of 100 to 120 compressions per minute and at a depth that allows adequate blood flow during cardiac arrest. For infants, achieving the proper compression depth is crucial because it maximizes the chances of restoring effective circulation while minimizing the risk of injury.

While the option stating about 1 inch may seem close, it does not meet the recommended depth needed to provide sufficient blood circulation during resuscitation efforts for an infant. The other options referring to deeper compressions are intended for adults and children, where the physiology allows for more forceful compressions without the risk of harm seen in infants.
