During CPR, how is breaching to a victim typically performed on an infant?

The two-thumb technique is the correct approach for delivering chest compressions to an infant during CPR because it helps to provide better control and effectiveness in compressing the chest. This method involves using both thumbs placed side by side on the lower half of the infant's sternum, while the fingers encircle the chest. This position allows for the application of adequate force while minimizing the risk of injury to the baby’s small and fragile body. It also ensures that compressions can be delivered at the appropriate depth and rate, which is crucial for effective resuscitation.

Using two fingers or a single palm is less effective for compressions on an infant. While these methods may be more common for specific situations, they do not provide the same level of control or strength as the two-thumb technique. Additionally, full hand placement, which is not appropriate for infants, could lead to excessive pressure that might harm the infant's chest structure. The two-thumb technique particularly aligns with the recommendations of various health organizations to ensure the highest level of care in critical moments.
