In CPR, how deep should chest compressions be performed on adults?

The depth of chest compressions for adults in CPR is crucial for effective circulation. The guideline specifies that chest compressions should be performed at a depth of at least 2 inches. This depth allows for adequate compression of the heart, ensuring that blood is effectively pumped throughout the body. Compressing to this depth also helps to create sufficient pressure within the thoracic cavity, which is essential for maintaining blood flow to vital organs during a cardiac emergency.

While options suggesting shallower or deeper compressions might seem reasonable, evidence-based guidelines emphasize the importance of reaching that minimum depth of 2 inches to optimize the chances of survival in cardiac arrest situations. Therefore, performing compressions that are too shallow could lead to ineffective resuscitation, while compressing deeper than necessary may cause injury to the rib cage or internal organs without providing additional benefits in circulation. Thus, the recommendation is firmly centered on achieving at least that 2-inch depth.
