Cardiac arrest occurs when the heart stops pumping blood around the body. If a person does not receive treatment, cardiac arrest can be lethal within minutes.
According to the American Heart Association (AHA), in the United States, around 475,000 people die from cardiac arrest each year.
It claims more lives than colorectal cancer, breast cancer, prostate cancer, pneumonia, influenza, vehicle accidents, firearms, HIV, and house fires combined.
