One of the primary components to the success of Medic One is their “Tiered Response System” which begins with the citizen call to the 9-1-1 center. Emergency Medical Dispatchers are trained to rapidly triage the call to dispatch the appropriate level of assistance, while providing pre-arrival instruction of CPR. Firefighters, with EMT training, respond first to deliver immediate Basic Life Support (BLS), pending the arrival of the paramedics. Specially trained paramedics arrive within minutes to provide Advanced Life Support (ALS) and, if needed, can provide transportation to the nearest appropriate Medical Center.
