What is the minimum recommended chest compression depth for adult CPR in centimeters?

• A. 4 cm
• B. 3 cm
• C. 5 cm
• D. 6 cm

Answer: (C)

In adult CPR, chest compressions must be deep enough to push blood out of the heart and generate circulation. The minimum depth recommended is about 5 centimeters (roughly 2 inches). Pressing at least this deep helps create the intrathoracic pressure needed to move blood to the brain and other vital organs. If compressions are shallower, like 3–4 cm, the blood flow is often insufficient and survival chances decrease. While deeper compressions around 5–6 cm can improve circulation, the key point for the minimum requirement is 5 cm, ensuring effective perfusion while aiming for proper technique and full chest recoil between compressions.
