What is the main goal of performing chest compressions during CPR?

The primary goal of performing chest compressions during CPR is to maintain blood flow to vital organs, particularly the heart and brain. When a person's heart stops beating, blood circulation ceases, leading to a lack of oxygen delivery to these critical areas. Chest compressions create artificial circulation by manually pumping blood, which helps ensure that oxygen continues to reach the brain and other vital organs, thereby increasing the chances of survival until advanced medical help arrives.

While assisting with breathing, stimulating consciousness, or clearing the airway are important aspects of the overall resuscitation process, they are not the primary focus during chest compressions. Instead, the key function of compressions is to sustain perfusion and preserve organ function as long as possible. This foundational understanding of CPR underscores the critical nature of maintaining blood flow when the heart is unable to do so on its own.
