What is the recommended method for providing compressions to an infant?

Using two fingers on the lower half of the sternum is indeed the recommended method for providing compressions to an infant during CPR. This technique is specifically designed to deliver effective compressions while minimizing the risk of injury to the delicate chest structure of an infant. When performing compressions, it's essential to compress the chest at a depth of about 1.5 inches and at a rate of 100 to 120 compressions per minute.

This approach allows for adequate blood circulation during cardiopulmonary resuscitation (CPR) while being gentle enough for a smaller and more fragile chest cavity. The use of two fingers provides the precision needed to target the correct area on the sternum without applying excessive force, which could occur if using a larger surface area, such as a full hand or interlocked hands.

In the context of infant CPR, using one hand, interlocked hands, or the heel of one hand tends to provide less control and may result in improper compression positioning or depth, which is why those methods are not recommended for this age group.
