What is the recommended compression depth for infants during CPR?

The recommended compression depth for infants during CPR is at least 1.5 inches (4 cm). This guideline ensures that adequate blood flow can be generated to vital organs during the critical moments of cardiac arrest. Compressions that are too shallow may not create the necessary pressure to effectively circulate blood, thereby reducing the chances of survival.

Achieving a depth of 1.5 inches allows for optimal cardiac compression without risking injury to the infant's delicate ribcage and internal organs, which are particularly vulnerable. This depth is based on studies and expert consensus that take into account both the size and physiological considerations of infants during resuscitation.

The other options suggest compression depths that either exceed the recommended guidelines or do not adequately reflect the need for effective circulation during CPR. Therefore, understanding and adhering to the correct compression depth is crucial for providing appropriate care in emergency situations involving infants.
