What is the recommended depth for chest compressions in CPR?

The recommended depth for chest compressions in CPR is 2 inches. This depth is essential to ensure that enough pressure is applied to the chest to create adequate blood flow to the heart and brain during a cardiac arrest. Compressions of this depth allow for effective circulation, which can significantly increase the chances of survival and recovery for the individual receiving CPR.

Compressions that are too shallow, such as those of 1 inch or 1.5 inches, may not be sufficient to generate the necessary blood flow. On the other hand, compressions deeper than 2.5 inches can potentially cause harm, such as rib fractures or damage to internal organs, particularly in smaller adults or children. Therefore, adhering to the guideline of 2 inches strikes the right balance between efficacy and safety in performing CPR.
