EMS Care EMT Chapter 24-MCIT-F3-2142 | Multi-Casualty Event and Field Triage  starts with an introduction to this important topic. In Emergency medical situations, EMTs must be prepared for situations where the number of patients exceeds available resources. Ùnlike routine calls, Multi-Casualty Incidents require a structured approach to ensure that greatest numbers of lives are saved with the available resources at hand. Field Triage is a critical component of MCI response, helping EMS personnel quickly assess and prioritize patients based based on the severity of Injuries and chances of survival. The lessons covered in this chapter are

• Lesson 1: Initial Response And Scene Size-Up
• Lesson 2: MCI Triage Systems & Patient Classification
• Lesson 3: Treatment Area Operations
• Lesson 4: Transportation Management
• Lesson 5:  Command and Control
• Lesson 6: Documentation And After-Action Review

 

Excerpt from EMS Care EMT Chapter 24-MCIT-F3-2142 | Multi-Casualty Event and Field Triage

Let’s look at each triage category in detail. Red tags go to patients with life threats requiring immediate intervention—for example, a patient with an arterial bleed.​

Yellow tags are for serious injuries that aren’t immediately life-threatening, such as a fractured major long bone. ​

Green tags are for patients who can walk and have sustained minor injuries. ​

​Black tags are reserved for patients who have either suffered obvious death or sustained injuries so catastrophic that survival is highly improbable given the limited resources of an MCI. This category includes individuals who may still have vital signs but whose injuries exceed the resources available.  For instance, if you encounter a patient with snoring respirations that do not improve after basic airway repositioning maneuvers, this indicates severe neurological compromise that would warrant a black tag in an MCI scenario. This difficult classification acknowledges that dedicating limited resources to patients with minimal chance of survival could compromise the care of those with better prospects of recovery.​

The black tag represents one of the most challenging ethical aspects of disaster triage—recognizing when providing comfort measures rather than intensive interventions serves the greater good of all patients at the scene​
