WEMS has 25 ambulances, 1 Major Incident Response Vehicle (MIRV), 1 bariatric ambulance, 4 District Medical Supervisors, and 1 Superintendent of EMS operations. Since 2002, WEMS operates 1 PACER (Paramedics Active in Community Education and Response), which is a pair of specially outfitted paramedics deployed on bicycles during the summer months (weather and staffing permitting). District Medical Supervisors use chase vehicles to assist paramedics on ambulance with pediatric and high-acuity calls and review paramedics' performance for continuous quality improvement. The superintendent oversees all EMS operations and, if required, can respond as a medical supervisor.
