What is the primary purpose of chest compressions during CPR?

The primary purpose of chest compressions during CPR is to improve blood circulation. When a person’s heart stops beating, the normal flow of blood to vital organs ceases, which can lead to irreversible damage in just a few minutes. Performing chest compressions helps to manually pump blood through the heart and vital organs, providing essential oxygen and nutrients, and maintaining a level of circulation that can sustain life until advanced medical help arrives. This process is critical in increasing the chances of survival and reducing the risk of long-term damage to the brain and other organs.

While restoring normal breathing, clearing the airway, and stabilizing the spine are important components of comprehensive patient care, they do not directly address the immediate need to circulate blood effectively during cardiac arrest. Hence, enhancing circulation through chest compressions is the foremost priority in a CPR situation.
