About the EMS System

Alameda is the seventh most populous county in California, and has 14 incorporated cities and several unincorporated communities. The total population is estimated to be 1,647,704. Oakland is the seat of County government and the County’s largest city. Alameda County is characterized by rich diversity and culture. Population growth has occurred with the natural net increase of births over deaths, but also from substantial immigration, and Alameda County is now one of the most ethnically diverse regions in the Bay Area and the nation.

During 2016, Alameda County received nearly 160,000 911 requests for medical aid, with over 115,000 transports being completed. The system has numerous components including communication centers, first responders, basic and advanced transports services, and multiple receiving and specialty care centers. To learn more about the various partners that support our EMS System, view each of the tabs below.

Communication Centers

Access to the EMS System begins with 911 and the emergency communication centers serving Alameda County. In Alameda County there are eighteen Public Safety Answering Points (PSAPs)- these centers perform initial intake of 911 calls and direct callers to the needed resource.

Two of the eighteen of the PSAPs in Alameda County are Accredited Emergency Medical Dispatch (EMD) Centers that utilize the Medical Priority Dispatch System (MPDS) to triage calls and assist callers in rendering immediate lifesaving care to those in need. To learn more about MPDS and how it helps patients, visit International Academies of Emergency Dispatch's Website.
