What is the CPR chest compression depth for adults?
Show answer and explanation
Correct answer: B. 2 inches
Per AHA 2020 guidelines, chest compressions for adults should be at least 2 inches (5 cm) deep but no more than 2.4 inches (6 cm). Rate: 100-120 compressions/min. For children: ~2 inches. For infants: ~1.5 inches. Inadequate depth fails to circulate blood effectively. Excessive depth can cause internal injury.
