What is the recommended compression depth for adult CPR?

The recommended compression depth for adult CPR is 2 inches (5 cm). This depth is supported by guidelines established by organizations such as the American Heart Association. The reasoning behind this recommendation is based on ensuring effective chest compressions that can generate sufficient blood flow during cardiac arrest. Compressions at this depth create the necessary pressure to mimic the natural pumping of the heart, leading to better outcomes for individuals experiencing cardiac arrest.

Compressions that are too shallow might not adequately circulate blood to vital organs, which is crucial for survival. Conversely, compressions that are too deep can lead to injury to the chest or internal organs. Thus, the 2-inch depth strikes a balance, allowing for effective compression without excessive risk of injury, making it the standard for performing CPR on adults.
