How should a rescuer position their hands during chest compressions?

During chest compressions, the correct positioning of the hands is crucial for effective resuscitation. Placing the hands over the heart area, specifically the lower half of the sternum, ensures that compressions are delivered directly to the heart, maximizing blood flow and circulation. This area is anatomically ideal because it allows for the most effective mechanical compression of the heart, which is located directly behind the sternum.

Proper hand positioning also promotes optimal depth and recoil during compressions, which is vital for maintaining sufficient blood flow to vital organs. Understanding the anatomy and the mechanics of chest compressions strengthens the rescuer’s ability to perform CPR effectively and can significantly impact patient outcomes.
