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

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

Answer: (A)

Chest compression depth scales with chest size. For infants, the chest is small, so compressions should be shallow but effective—about one third of the chest’s depth. That typically works out to roughly 1/2 to 1 inch. Deeper compressions are used for older children and adults because their chests are larger and require more depth to reach the heart. Newborns are treated similarly to infants, with shallow depths in the same range. So the 1/2 to 1 inch range best fits the infant age group.
