What is the focus of chest compressions during CPR?

To circulate blood to the brain
To prevent airway obstruction
To maintain normal heart rhythm
To assist with breathing

The correct answer is: To circulate blood to the brain

The focus of chest compressions during CPR is primarily to circulate blood to the brain and other vital organs. When a person experiences a cardiac arrest, their heart stops pumping blood effectively, which leads to a lack of oxygen being delivered to the brain. This absence of blood flow can cause brain damage in just a few minutes. By performing chest compressions, the rescuer creates artificial circulation, pressing down on the chest to generate blood flow. This action helps sustain vital organs, especially the brain, until advanced medical help arrives or until the heart can be restarted. Maintaining blood flow is critical because it buys time for the person and increases the chances of survival with favorable outcomes. While airway management, heart rhythm stabilization, and breathing assistance are important during a complete CPR process, the immediate goal of chest compressions is to ensure that blood continues to flow, especially to the brain.
