Cardiac arrests treated by ambulance paramedics and fire fighters - The Emergency Medical Response program

The Emergency Medical Response (EMR) program is a Victorian Government initiative in which fire fighters trained in cardiopulmonary resuscitation and equipped with automatic external defibrillators are dispatched to suspected cardiac arrests simultaneously with ambulance paramedics across metropolitan Melbourne, During the first 12 months (February 2000 to February 2001) of the expanded EMR program, 2942 events involved simultaneous dispatch of ambulance paramedics and fire fighters. In 430 events, patients had suffered a cardiac arrest of presumed cardiac cause, and resuscitation was attempted by the emergency medical services, Fire fighters provided the initial defibrillation to 41 (26.5%) patients presenting in ventricular fibrillation. Survival to hospital discharge for bystander-witnessed ventricular fibrillation cardiac arrests was 21.8%. The mean emergency services (fire and ambulance) response time to cardiac arrest patients was 6.03 (SD, 1.65) minutes. The mean time to defibrillation for ventricular fibrillation patients was 8.75 (SD, 2.07) minutes.
