What is the main goal of CPR in the event of cardiac arrest?

The primary objective of CPR during a cardiac arrest is to maintain blood flow to the brain and heart until emergency medical services can take over. When the heart stops pumping effectively, blood circulation ceases, leading to a rapid decline in oxygen delivery to vital organs, particularly the brain. CPR helps to artificially circulate blood through chest compressions, ensuring that these critical components of the body continue to receive some level of oxygenated blood.

Without immediate intervention, brain cells can begin to die within minutes due to a lack of oxygen, resulting in irreversible damage. By prioritizing blood flow, CPR buys valuable time for professional responders to arrive and provide advanced care, increasing the chances of survival and minimizing long-term effects.
