What should be the depth of chest compressions during CPR for an adult?

Explanation:
In adult CPR, the goal is to push hard enough to move blood through the heart and circulate it. The target depth is about 2 inches (5 cm) for an average adult. This depth balances generating sufficient blood flow with minimizing the risk of injury; some guidelines allow up to around 2.4 inches (6 cm), but 2 inches is the standard target. The shallower depths (around 1 to 1.5 inches) won’t reliably generate adequate perfusion, while too deep (about 3 inches) can increase (and not significantly improve) injury risk. Remember to deliver compressions at a steady rate (approximately 100–120 per minute) with full chest recoil between compressions.
