How deep should compressions be during adult CPR?

• A. Less than 1 inch
• B. 1 to 2 inches
• C. 2 to 2.4 inches
• D. 2.4 to 3 inches

Answer: (C)

During adult CPR, the guidelines recommend that chest compressions should be performed at a depth of 2 to 2.4 inches (approximately 5 to 6 cm). This depth is necessary to ensure effective compressions that can adequately circulate blood and deliver oxygen to vital organs. Proper compression depth allows for sufficient release and recoil of the chest, which is crucial for the heart to refill with blood between compressions. The recommended depth strikes a balance between being deep enough to facilitate perfusion and preventing potential injury to the chest structure. Compressions that are too shallow may not deliver the necessary blood flow to the brain and other critical areas, while excessively deep compressions can lead to rib fractures and other injuries without significantly improving outcomes. This guideline aligns with the most current cardiopulmonary resuscitation (CPR) practices and emphasizes the importance of training and adherence to these protocols by responders.
