What is the primary purpose of compressions during CPR?

The primary purpose of compressions during CPR is to circulate blood to vital organs. When someone suffers a cardiac arrest, their heart stops beating effectively, which means blood is no longer being pumped throughout the body. High-quality chest compressions create artificial circulation, helping to maintain blood flow to the brain and other critical organs. This is crucial because it helps to preserve the function of these organs until more advanced medical help can arrive, such as defibrillation or other emergency interventions.

While keeping the airway open and providing oxygen are important components of overall CPR, the immediate and critical action is to restore blood circulation. This helps to deliver oxygen-rich blood to the heart and brain, minimizing damage and improving the chances of survival. Stimulation of the heart might occur as a result of effective compressive actions, but the main goal remains the restoration of blood flow.
