The paramedics at Portland International Airport respond to a variety of calls and fill various roles depending on the nature of the emergency. They are prepared to establish a “medical branch” for the triage, treatment and transport of multiple victims of an aircraft disaster, structural fire, vehicle accident or similar emergency. Medical emergencies comprise approximately 65 percent of all calls at PDX. Many of the ill or injured patients are travelers, some far away from home. Paramedics play a vital role in the airport's customer service efforts.

The paramedics work under regional protocols, a physician advisor and standing orders. The scope of practice for paramedics in Multnomah County is one of the most progressive in the nation, allowing them to offer “cutting edge” pre-hospital treatment for their patients.
