(Portland, OR) -- There's increasing pressure on Multnomah County Chair Jessica Vega Pederson to relax the requirement of two paramedics on AMR Ambulances. AMR says it can't meet the requirement, because of the nationwide shortage of paramedics. The Portland and Gresham city councils have passed resolutions calling on Multnomah County to allow a one paramedic and one EMT staffing level. Firefighters would provide the second paramedic. The Multnomah County Commission meets on Thursday, but it's not expected to consider the ambulance issue until next week.
