What is the primary purpose of performing CPR?

To restore breathing
To increase blood flow to the heart
To circulate oxygen in the body
To prevent brain damage

The correct answer is: To prevent brain damage

The primary purpose of performing CPR is to prevent brain damage by ensuring that blood continues to circulate to the brain and other vital organs. When the heart stops beating, circulation ceases, leading to a rapid decline in oxygen delivery to the brain. Brain cells can begin to suffer damage within minutes due to a lack of oxygen, which is why immediate CPR is critical. While restoring breathing and circulating oxygen are important components of resuscitation efforts, these actions are secondary to the primary goal of maintaining perfusion to the brain. By compressing the chest during CPR, blood is mechanically circulated, which helps to maintain blood flow and minimizes the risk of neurological impairment. Increasing blood flow to the heart is a beneficial effect of CPR, but it is not the foremost goal. The overarching aim is to protect the brain from irreversible damage resulting from hypoxia. Therefore, the prevention of brain damage serves as the primary motivation for initiating CPR in cases of cardiac arrest.
