What is the correct chest compression depth for a child who has reached puberty?

The correct chest compression depth for a child who has reached puberty is at least 2 inches but no more than 2.4 inches. This depth is in alignment with the guidelines provided by organizations such as the American Heart Association. When performing CPR on individuals who are at least the age of puberty, it is crucial to provide effective chest compressions that are deep enough to create sufficient blood flow during cardiac arrest. The specified depth ensures that the compressions can adequately compress the heart between the sternum and the spine, which is essential for maintaining circulation during resuscitation efforts.

Guidelines for infants and younger children indicate shallower compression depths due to their smaller chest sizes and developmental stages, which is why understanding the age and developmental milestones is critical in CPR technique. Thus, this choice reflects a clear understanding of appropriate protocols for chest compressions in the context of child CPR.
