Where should chest compressions be applied on an adult?

Chest compressions on an adult should be applied to the lower half of the sternum. This area is specifically chosen because it is located at the center of the chest, which helps ensure that the compressions are effective in maintaining blood circulation during cardiopulmonary resuscitation (CPR). The lower half of the sternum is the optimal location for compressions, as it provides direct pressure to the heart, allowing for better blood flow to vital organs.

When performed correctly, compressions focused on this area can effectively pump blood, which is crucial for individuals who have experienced cardiac arrest. The technique also involves rhythm and depth, with recommendations for compressions to be at least 2 inches deep at a rate of 100 to 120 compressions per minute, which can help maximize the chances of survival until emergency medical services are able to arrive.
