How deep should chest compressions be in an adult?

The recommended depth for chest compressions in an adult during CPR is at least 2 inches, but not more than 2.4 inches. This depth is crucial because compressions at this range are effective in generating sufficient blood flow to vital organs while minimizing the risk of causing serious injury to the ribs and sternum.

Providing compressions that are too shallow may not be effective enough to circulate blood, which can lead to poor outcomes. On the other hand, compressions that are excessively deep may increase the risk of injuries, such as rib fractures or damage to internal organs. The guideline emphasizes this specific range to balance effectiveness with safety, ensuring that CPR is both efficient and minimizes harm to the patient.

This standard aligns with recommendations from the American Heart Association, which underscores the importance of proper compression depth in enhancing the chances of survival in cases of cardiac arrest.
