When it comes to cardiac emergencies, seconds can make the difference between life and death. Sudden cardiac arrest (SCA) is a condition where the heart unexpectedly stops beating, cutting off blood flow to the brain and other vital organs. Without immediate intervention, the survival rate drops dramatically by 7–10% for every minute that passes without treatment. While hospitals and emergency medical services (EMS) play a critical role in treating cardiac emergencies, police officers are increasingly recognized as the first line of defense in saving lives.
