What is the minimum chest compression depth for adults and children during CPR?

• A. 1 inch
• B. 1.5 inches
• C. 2.5 inches
• D. 2 inches

Answer: (D)

The depth of chest compressions determines how well blood is pushed out of the heart to circulate to the brain and organs. For adults and children older than about 1 year, the minimum depth recommended is about 2 inches (5 cm). This depth is deep enough to generate meaningful blood flow without being so deep that it causes unnecessary injury. Shallow compressions, like 1 inch or 1.5 inches, don’t produce adequate perfusion. A depth of 2.5 inches goes beyond the minimum and can be appropriate in many cases, but the question asks for the minimum that reliably meets perfusion needs, which is 2 inches.
