What is the primary purpose of CPR?

The primary purpose of CPR, or cardiopulmonary resuscitation, is to restore heartbeat and breathing to a patient who has suffered a cardiac arrest or respiratory failure. This life-saving procedure aims to maintain vital blood flow to the brain and other organs until advanced medical help can arrive. When performed effectively, CPR can significantly increase the chances of survival and can prevent further damage to the body during a critical emergency.

In a situation where a person stops breathing or their heart stops beating, immediate CPR can provide necessary oxygenation and circulation. This is achieved through chest compressions and rescue breaths, which facilitate blood flow and oxygen delivery to the body’s tissues. Understanding the importance of CPR emphasizes the need for timely and effective intervention in life-threatening situations.

Other options mentioned do not directly address the life-threatening scenarios that CPR is designed to respond to, such as emotional support, pain relief, or diagnosis of medical conditions, which are important aspects of patient care but separate from the urgent action required during a cardiac emergency.
