What is the recommended depth of chest compressions for adults during CPR?

The recommended depth of chest compressions for adults during CPR is at least 2 inches. This depth is crucial for generating sufficient pressure to effectively compress the heart and facilitate blood flow to vital organs during cardiac arrest. Compressing to this depth ensures that enough blood is pumped out of the heart with each compression, which is vital for maintaining circulation and can significantly improve the chances of survival until advanced medical care is available.

Depths less than 2 inches may not produce adequate blood flow, reducing the effectiveness of CPR. Therefore, adhering to the minimum recommendation of 2 inches is essential for optimal outcomes during attempts to revive someone who has stopped breathing or whose heart has stopped. It aligns with the guidelines presented by organizations like the American Heart Association, which emphasize the importance of proper technique and depth in chest compressions to maximize the chances of successful resuscitation.
