Which age group is associated with a chest compression depth of 1 - 1 1/2 inches?

• A. Children
• B. Infants
• C. Adults
• D. Newborns

Answer: (A)

In CPR, how deep you press depends on the size of the chest, aiming for about one-third of the chest’s depth. For the tiniest patients, that depth is roughly 1.5 inches. As children get larger, the recommended depth increases toward about 2 inches, and adults about 2 to 2.4 inches. So a depth of 1 to 1.5 inches best matches newborns and infants. Children, being larger, require deeper compressions around 2 inches. This difference matters because enough depth is needed to generate circulating blood, while pressing too shallow can fail to provide adequate perfusion and pressing too deep can risk injury in smaller chests.
