Cardiac arrest occurs when the heart suddenly stops pumping blood due to a malfunction in its electrical system. Here are some key points from the knowledge base:

- Survival Rates: About 90% of people who experience out-of-hospital cardiac arrest die. However, nearly 45% survive when bystander CPR is administered.
- Case Example: Steve Regier experienced cardiac arrest while running. Bystanders Amanda Carrillo and Cooper Phillips administered Hands-Only CPR until EMS arrived, which significantly contributed to his survival.
- Causes: Steve's cardiac arrest was due to a combination of factors, including epinephrine intake, physical exertion in extreme heat, and undiagnosed fungal pneumonia.
- Treatment: Upon arrival at the hospital, Steve was put into a medically induced coma and his body temperature was lowered to reduce the risk of brain damage.
