What is the recommended compression depth for adult CPR?

The recommended compression depth for adult CPR is 2-3 inches. This depth is important because it ensures that sufficient pressure is applied to the chest to effectively compress the heart and maintain blood flow to vital organs during cardiac arrest. Compressions that are too shallow may not adequately circulate blood, reducing the patient's chances of survival. The American Heart Association (AHA) emphasizes the necessity of achieving this depth to optimize the effectiveness of chest compressions. This range allows for enough force to be exerted while also preventing potential injury to the chest or ribs, striking a balance that maximizes resuscitation efforts.
