TY - CHAP M1 - Book, Section TI - Cardiac Arrest A1 - Boyd, Tanner S. A1 - Perina, Debra G. A2 - Cooney, Derek R. Y1 - 2016 N1 - T2 - Cooney's EMS Medicine AB - EMS medical care provided to cardiac arrest patients has changed ­dramatically over time. Ambulances initially functioned merely as transport vehicles, while today EMS is an integrated part of the health care system with the ability to provide advanced life support while en route to a hospital. Regional dispatch centers now decide which resources should respond to an emergency call. Dispatchers, trained in emergency ­medical dispatch (EMD) techniques, have specific protocols to follow to ­determine whether basic life support (BLS) or advanced life support (ALS) EMS response is required. Prearrival instructions to bystanders can help expedite initial first aid or CPR.1–4 Recently protocols have expanded the role of EMS providers in treating out-of-hospital cardiac arrest (OCHA) patients ranging from beginning therapeutic hypothermia in the field to bypassing hospitals in favor of a specialized receiving facility.
