What is the recommended compression depth for adult CPR?

The recommended compression depth for adult CPR is at least 2 inches (5 cm). This depth is established based on studies that show deeper compressions are more effective in maintaining blood flow during cardiac arrest. The goal of chest compressions is to create enough pressure to circulate blood and provide oxygen to vital organs, particularly the heart and brain.

Compressing to this recommended depth ensures that enough volume of blood is being pushed through the heart, enhancing the chances of successful resuscitation. It is also important to maintain a compression rate of 100 to 120 compressions per minute to optimize effectiveness.

While options suggesting lesser or greater compression depths may seem plausible, they do not align with the established guidelines which emphasize the importance of at least 2 inches to maximize perfusion during CPR effectively.
