The most effective treatment for Sudden Cardiac Arrest is CPR and a shock administered from an AED as soon as possible. Law Enforcement Officers are often the first to arrive on the scene of an accident, before emergency medical personnel. By equipping Police Officers with AEDs, this allows the victim to receive care immediately, reducing the time until defibrillation and increasing the chance of survival. Many studies over the years have shown that equipping police cruisers with AEDs has improved the survival rates of SCA significantly. AEDs for police vehicles are portable and durable; compact and lightweight in order to carry long distances; as well as sturdy enough to withstand any situation.
