What is the primary purpose of CPR?

The primary purpose of CPR, or cardiopulmonary resuscitation, is to restore breathing and circulation in an individual who has experienced cardiac arrest or respiratory failure. When the heart stops beating, blood is no longer pumped to the organs and brain, which can lead to permanent damage if not addressed quickly. CPR involves chest compressions and, when appropriate, rescue breaths, which work together to maintain blood flow and oxygenation until professional medical help arrives or the person recovers. The technique is designed to mimic the heart's pumping action and to provide oxygen to the lungs, making it a critical life-saving skill. The focus on restoring circulation and breathing is essential in preventing irreversible damage and improving the chances of survival.
