What is the recommended compression depth for adult chest compressions?

The recommended compression depth for adult chest compressions during cardiopulmonary resuscitation (CPR) is indeed 2 inches (5 cm). This guideline is established based on research indicating that a compression depth of at least 2 inches is effective in providing adequate circulation during cardiac arrest. Compressing to this depth ensures that there is sufficient blood flow generated to the heart and vital organs, which is crucial for increasing the chances of survival.

Compressing too shallowly can result in ineffective compressions, while compressing deeper than the recommended depth could potentially cause injury to the ribs or internal organs. Therefore, adhering to the recommended depth of 2 inches helps to balance effectiveness and safety during CPR.
