What depth should compressions be performed at when giving CPR to an infant?

When performing CPR on an infant, compressions should be given to a depth of approximately one-third the depth of the infant's chest. This guideline is crucial because an infant's chest is considerably smaller and more vulnerable than an adult's, so the depth of compressions must be appropriate to ensure effective circulation without causing injury. The one-third depth provides an effective balance that allows for adequate blood flow to vital organs while minimizing the risk of trauma to the infant's delicate ribcage and internal structures. This practice emphasizes the importance of adjusting CPR techniques based on the size and physiological characteristics of the age group being treated.
