What is the recommended compression depth for infant CPR?

The recommended compression depth for infant CPR is important to ensure effective blood flow during resuscitation efforts. The guideline specifying that compressions should be at least one-third the diameter of the chest is based on anatomical considerations. Infants have smaller and more rigid rib cages, so compressing to that depth ensures sufficient force to generate adequate blood circulation without causing excessive injury.

This guideline allows for appropriate depth of compressions that engages the heart effectively to maintain circulation during emergencies. The depth is measured to ensure that the compressions are both effective and safe, striking a balance between sufficient depth to perfuse vital organs and minimizing the risk of injury to the infant's fragile body.

Other options may not provide the necessary depth or might be too shallow, compromising the effectiveness of the resuscitation effort or risking injury to the infant. It's crucial to adhere to the recommended depth and technique during infant CPR to maximize the chances of survival.
