Emergency Medical Services

Emergency Department physicians provide around-the-clock on-line medical direction of Philadelphia Fire Department EMS personnel as well as providers from surrounding counties. Emergency medicine residents participate in on-site medical coverage for city-sponsored special events throughout the year, including distance runs and mass gatherings. Through ambulance ride-alongs, lectures, and hands-on fireground training, residents get a better appreciation of the capabilities of, and challenges facing, prehospital medical providers and their firefighting colleagues.
