During CPR, how deep should chest compressions be for infants?

For infants, chest compressions should be performed to a depth of about 1.5 inches (approximately 4 centimeters). This depth is crucial because it ensures effective circulation and blood flow to vital organs during a cardiac emergency. Using the correct depth is vital for providing adequate compressions to the infant's body, which is smaller and more fragile compared to adults or children, thus requiring slightly less depth for compressions to be effective and safe.

While performing CPR, it is essential to allow full chest recoil between compressions to enable the heart to refill with blood. The technique must be adapted to the size and anatomy of the infant to maximize efficacy and minimize the risk of injury.
