How does the depth of compressions differ between children and infants?

The correct response emphasizes that children require deeper compressions at about 2 inches, whereas infants need compressions of about 1.5 inches. This distinction is crucial because the physiology of children and infants differs significantly in terms of body size and the resiliency of the chest wall. The deeper compressions for children are necessary to generate adequate blood flow during cardiac arrest, as their larger body mass demands a greater force to circulate blood effectively.

In contrast, infants require shallower compressions due to their smaller and more fragile body structure. Compressing the chest too deeply on an infant can lead to the risk of injuries, including damage to the ribcage and internal organs. Understanding these differences is vital for providing effective CPR tailored to the age group of the child or infant being cared for, ensuring both safety and efficacy in life-saving measures.
