Cardiopulmonary resuscitation, commonly referred to as CPR, is a critical emergency procedure that combines chest compressions and artificial ventilation to maintain blood flow and oxygenation to the brain and vital organs when a person’s breathing or heartbeat has stopped. Recognizing When to Use CPR You should initiate CPR if you encounter an unresponsive person who is not breathing normally, or only gasping, and who does not have a pulse.

The standard ratio for adult CPR is typically 30 compressions followed by 2 rescue breaths, although hands-only CPR omits the breaths and focuses solely on continuous compressions. Understanding the Purpose of CPR The primary goal of CPR is to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
By pushing on the chest at a specific rate and depth, a rescuer can manually compress the heart, pushing oxygenated blood to the brain and other critical organs. Formal certification courses teach the correct techniques, including hand placement, compression depth, and rate, ensuring confidence and effectiveness during an emergency.

The Science Behind Circulation When the heart stops, blood no longer circulates, depriving the brain and organs of oxygen. CPR manually circulates a small amount of oxygenated blood through the body, significantly slowing the progression of brain damage.
