For effective CPR on adults, how deep should compressions generally go?

When performing CPR on adults, the recommended depth for chest compressions is generally about 2 inches. This depth is crucial because it allows for adequate blood circulation, ensuring that enough blood is being pumped to vital organs, particularly the brain and heart. Compressions that are too shallow may not generate sufficient pressure to circulate blood effectively, which can greatly diminish the chances of survival in a cardiac arrest situation.

Compressions at this depth also help create a positive pressure within the thoracic cavity, which is essential for effective blood flow during the cardiac cycle. The target range for adult compressions is between 2 to 2.4 inches, but aiming for a depth of 2 inches strikes a balance between being effective and safe for most adult patients. It is important to allow the chest to fully recoil between compressions to maximize blood flow.
