What is the recommended depth of chest compressions in an adult patient during CPR according to current AHA guidelines?

Current American Heart Association (AHA) guidelines recommend that chest compressions in adult CPR be performed to a depth of at least 2 inches (5 cm) but no more than 2.4 inches (6 cm). Compressions should be delivered at a rate of 100 to 120 per minute, allowing full chest recoil between compressions. Adequate compression depth is essential for generating sufficient cardiac output during cardiac arrest. Compressions that are too shallow (less than 5 cm) are associated with worse survival outcomes.
