For infants, what is the recommended compression depth during CPR?

The recommended compression depth for infants during CPR is to compress the chest to about one-third of the chest's depth. This typically translates to approximately 1.5 inches. The rationale behind this guideline is based on the anatomical characteristics of infants; their chest walls are more compliant compared to adults, and compressing to one-third of the chest ensures that sufficient pressure is applied to maintain circulation without causing harm. This depth promotes effective chest compressions that can circulate blood and oxygen to vital organs, which is crucial during a cardiac emergency.

The alternative choices, while quantifying depth, do not align with the best practice standards for infant CPR, which emphasize the importance of proportionality to the size of the chest rather than a set measurement.
