In CPR for an adult, what is the required chest compression depth?

In adult CPR, chest compressions should be about 2 inches deep (roughly 5 cm). This depth is enough to generate meaningful blood flow by pressurizing the chest so the heart pumps blood to vital organs. Compressing only about 1 inch yields poor perfusion, while going significantly deeper than about 2.4 inches increases the risk of injury and can interfere with full chest recoil. So aim for around 2 inches, allow complete chest recoil between pushes, and maintain a rate of about 100–120 compressions per minute.
