How Does CPR Work?

Cardiopulmonary resuscitation (CPR) works by a rescuer providing chest compressions and ventilations to maximize blood and oxygen saturation to vital organs in the event of a sudden cardiac arrest (SCA). If CPR is administered within the first 3-5 minutes, the survivability after a SCA significantly increases. Cardiopulmonary resuscitation provides crucial blood flow and oxygen to the heart and brain. The use of an Automated External Defibrillator (AED) with CPR can provide an electric charge to the victim to re-establish a normal heart rhythm. Following the prompts from the AED and applying the pads correctly is essential for proper usage. Quickly administering high-quality CPR and using an AED can mean the difference between life and death for a victim.
