What compression depth is recommended during adult CPR?

• A. 2 inches (5 cm)
• B. 1 inch (2.5 cm)
• C. 3 inches (7.5 cm)
• D. 4 inches (10 cm)

Answer: (A)

Compression depth in adult CPR determines how much blood is moved with each push. For an adult, aim to press the chest about 2 inches (5 cm) deep. This depth is enough to compress the heart and push blood out into the circulation, helping to perfuse the brain and other vital organs. Pressing shallower than this won’t generate adequate forward flow, reducing the effectiveness of CPR. Going much deeper can raise the risk of injuries like rib or tissue damage without providing added benefit. Maintain full chest recoil between compressions and keep the rate around 100–120 compressions per minute to maximize perfusion.
