The document discusses triage protocols for mass casualty incidents (MCIs). It describes several triage tools and systems used in emergency medicine to prioritize patient care based on severity of injury, including START, SALT, and ABCDE approaches. The goal of triage is to maximize survival by allocating limited healthcare resources to patients with the most life-threatening injuries first. Patients are assigned triage tags or sorted into categories like Red (immediate), Yellow (delayed), Green (walking wounded), and Black (deceased/expectant).
