What is the appropriate depth for chest compressions for adults?

The appropriate depth for chest compressions for adults during cardiopulmonary resuscitation (CPR) is at least 2 inches. This depth is crucial because compressions that are too shallow may not effectively circulate blood to the vital organs, particularly the heart and brain. According to guidelines set by organizations such as the American Heart Association, compressions should be performed at a depth of about 2 to 2.4 inches to ensure adequate perfusion.

This depth allows for sufficient compression of the heart, which is essential for maintaining blood flow during a cardiac emergency. Using the right depth also ensures that the chest fully recoils between compressions, enhancing the effectiveness of each compression. The guidelines emphasize proper technique, ensuring both the depth and the rate of compressions align with best practices for improving the chances of survival after cardiac arrest.
