What does red color signify in a mass casualty incident?

In the context of a mass casualty incident, red color signifies "critical" patients. This classification is part of a triage system used by emergency responders to prioritize care based on the severity of injuries. Patients marked with red are those who require immediate medical attention due to life-threatening conditions. This could include severe bleeding, compromised airways, or other critical injuries that, if not treated quickly, could lead to death.

The use of color coding helps responders efficiently manage resources and provide care based on the urgency of each patient's needs, ensuring that those who need immediate help receive it first. This system is essential in chaotic situations where many individuals may be injured.
