What specific technique is used for infants during CPR?

When performing CPR on infants, the technique involves using two fingers for chest compressions. This method is designed to provide adequate pressure while being gentle enough to prevent injury to the fragile ribcage of an infant. The compressions should be delivered at a depth of about 1.5 inches, which is appropriate for the infant's anatomy and ensures that the heart is effectively compressed to circulate blood.

Using two fingers helps to target the correct area on the infant’s chest, which is just below the nipple line in the center of the chest. This technique not only promotes effective blood circulation but also minimizes the risk of trauma to the infant's soft bones. The specific depth of 1.5 inches is critical for achieving the necessary compression while maintaining safety.

The other options present techniques that are either inappropriate for infants or do not follow established guidelines for infant CPR. The method chosen is essential for ensuring the safety and effectiveness of CPR in young children, where anatomical considerations are significantly different from those of adults.
