What is the primary purpose of chest compressions during CPR?

The primary purpose of chest compressions during CPR is to pump the heart. When a person experiences cardiac arrest, their heart stops beating effectively, which means blood cannot circulate to vital organs, including the brain. Chest compressions create artificial circulation by compressing the chest, which helps maintain blood flow and oxygenation to the organs. This is crucial in increasing the chances of survival and minimizing brain damage until advanced medical help can be delivered.

While clearing the airway and other options may play roles in CPR, they are secondary actions compared to the critical function of maintaining circulation through effective chest compressions. The goal is to keep the blood flowing to the brain and other organs as long as possible in order to restore normal heart function and consciousness.
