In adult CPR, how deep should chest compressions be?

In adult CPR, the recommended depth for chest compressions is about 2 inches. This depth is essential to effectively compress the heart and enable it to pump blood to vital organs. When compressions are too shallow, they may not generate sufficient pressure to circulate blood, significantly reducing the chances of survival for the victim.

Compressions should allow for full chest recoil between compressions, as this aids in blood flow back to the heart. The guideline of about 2 inches strikes a balance between being deep enough to maintain circulation and minimizing the risk of injury to the ribs and sternum.

Understanding the importance of this depth ensures the effectiveness of the CPR technique being employed and highlights the importance of adhering to established guidelines for optimal outcomes in cardiopulmonary resuscitation.
