What is the recommended compression depth for adult chest compressions during CPR?

The recommended compression depth for adult chest compressions during CPR is between 2 to 2.4 inches. This depth is crucial because it ensures that adequate blood flow is generated during compressions, allowing for the effective return of blood to the heart and perfusion of vital organs. Compressions of this depth help to maintain adequate pressure in the circulatory system, which is essential for improving the chances of survival in a cardiac arrest situation.

Maintaining this recommended depth is supported by guidelines that aim to optimize the chances of successful resuscitation by ensuring that compressions are not only deep enough to be effective but also consistent in quality. Depths below 2 inches may not provide sufficient pressure to pump blood effectively, while compressions over 2.4 inches may increase the risk of injury to the chest, particularly in older adults or those with weakened bones. Thus, adhering to the guideline of 2 to 2.4 inches strikes a balance between effectiveness and safety in the resuscitation process.
