What is the definition of Green in triage categories?

• A. Not applicable in EMS.
• B. Serious, but not critical.
• C. Low acuity of illness/injury.
• D. Immediate life-threatening.

Answer: (C)

Triage uses color codes to quickly separate patients by urgency. The green category signals low acuity: injuries or illnesses that are minor and can wait, with patients typically able to walk and function with minimal treatment. This helps responders reserve time and resources for those in more urgent need—red for immediate life threats and yellow for delayed care. The option describing green as low acuity best fits this standard. The other concepts don’t apply because immediate life-threatening conditions are classified as red, serious but not critical as yellow, and “not applicable” isn’t how EMS triage operates.
