Multi-Casualty Incidents

Triage

An emergency event involving five or more patients in El Dorado County is defined as a "Multi-Casualty Incident" or MCI. Usually overwhelming the capacity of initial responders, an MCI requires close coordination and prompt of additional resources to rapidly triage, treat and transport patients from the scene to definitive care.
