What is the primary purpose of CPR?

The primary purpose of CPR (Cardiopulmonary Resuscitation) is to maintain blood circulation and oxygenation to the brain and other vital organs when a person's heart has stopped beating or when they are not breathing effectively. When the heart ceases to function properly, oxygenated blood cannot reach the brain and other critical areas of the body. Without immediate action, this can lead to irreversible damage or death within just a few minutes.

By performing CPR, chest compressions are used to manually pump blood and provide oxygen to the brain and other organs. This is crucial in increasing the chances of survival until emergency medical services arrive or until an automated external defibrillator (AED) can be used to restore a normal heart rhythm. The technique directly supports the body’s need for oxygen, which helps to sustain life during a critical moment when bodily functions are compromised.

While diagnosing a heart attack, administering medication, and preventing drowning are important skills and actions in emergency response, they are not the primary focus of CPR. CPR specifically addresses the immediate needs of a person who is unresponsive and not breathing, making it a vital emergency procedure in saving lives.
