How deep should chest compressions be for adults during CPR?

The recommended depth for chest compressions in adults during CPR is 2 inches. This depth is critical for generating adequate blood flow and ensuring that the heart is effectively compressed to circulate oxygenated blood to vital organs. When performing chest compressions, the compressions should allow the chest to fully recoil between compressions while maintaining the 2-inch depth. This protocol is based on research and guidelines established by organizations such as the American Heart Association, which emphasize that this depth promotes optimal outcomes in cardiac arrest situations.

Shallow compressions, such as 1 inch, may not be effective in achieving the necessary pressure to circulate blood, while depths greater than 2 inches, such as 3 or 4 inches, can increase the risk of injury to the patient, including potential damage to internal organs or fractures of the ribs. Therefore, adhering to the 2-inch guideline is crucial for both efficacy and patient safety during CPR.
