The Seattle & King County Emergency Medical Services System is a fire-based two-tier response system providing prehospital basic and advanced life support services. There are six paramedic provider programs in the system. The Seattle Fire Department operates Seattle Medic One. The program is funded by the city's general fund and has a different administrative structure than the five other Medic One programs. The five other Medic One programs with the exception of King County Medic One are operated by fire departments under a formal contract with the EMS Division of Public Health - Seattle & King County. King County Medic One is directly operated by the EMS Division. The modern EMS system in King County began operation in 1970 with 15 paramedics staffing one paramedic unit in Seattle. In 2009, there were 255 paramedics from six paramedic programs staffing 26 paramedic units. The system is a dynamic layered response system. An EMS response to an emergency begins with a telephone call to 9-1-1. Calls are transferred from a primary call taker to emergency medical call taker who gathers information from the caller, gives instructions to the caller, and determines what types of emergency personnel to send. For very serious and life-threatening emergencies firefighters trained in basic life support and paramedics trained in advanced life support respond simultaneously. Paramedics transport patients in critical condition. For less severe emergencies only firefighters will be dispatched. Basic life support personnel from either a fire department or private ambulance company transport non-critical patients. History In 1968, motivated by the work of Frank Pantridge, cardiologist Leonard Cobb proposed to the chief of the Seattle Fire Department, Gordon Vickery, training firefighters to treat cardiac arrest. The department was attractive to Cobb because it already provided first aid and tracked its performance electronically. In 1969, they trained fifteen firefighters and used a grant from the Washington/Alaska Regional Medical Program to convert a large motor home into a Mobile Coronary Care Unit nicknamed "Moby Pig", which would respond to calls with both the firefighter paramedics and a physician on board. The first Medic One call was on March 7, 1970. During the program's first year, 31 lives were saved. The following year the program was changed, replacing the on-board doctors with fire department paramedics given advanced special training and remote access to the doctors. In 1974, the TV news-magazine 60 Minutes profiled the success of Medic One, lauding the
