Which technique is most appropriate for giving chest compressions to an infant?

The most appropriate technique for giving chest compressions to an infant involves using two fingers slightly below the nipple line. This method is designed specifically for the anatomy and physiology of infants, who have fragile rib cages and a smaller chest size compared to older children and adults.

By using two fingers, you can apply the necessary depth and rate of compressions while minimizing the risk of causing injury to the infant's chest. The placement is crucial; compressions should be performed just below the nipple line to effectively compress the heart against the spine, which is essential for maximizing blood flow during resuscitation efforts.

Other techniques, such as using both hands or the palm of one hand, are not appropriate for infants due to the risk of causing damage to their softer chest structures. Similarly, pressing quickly with fingertips does not provide the depth or sustained pressure required for effective compressions. The two-finger technique ensures that compressions are effective while being safe for the vulnerable anatomy of an infant.
