What is the recommended technique for performing chest compressions on an infant during CPR?

Using two or three fingers is the recommended technique for performing chest compressions on an infant during CPR because it allows for a more controlled and gentle application of force, which is crucial given the fragility of an infant's chest. This method involves placing the fingers just below the nipple line on the infant's sternum and compressing at a depth of about one-third the depth of the chest.

Using the palms of both hands, one hand, or the heel of the hand can be inappropriate for infants, as these methods may generate too much force and could potentially cause injury to the developing ribcage or organs. Proper technique is essential not only to ensure effective circulation during cardiac arrest but also to minimize the risk of harm to the patient in such a vulnerable age group.
