📒 The 1-minute cheat sheet
📌 Er Tags
Red = immediate, life threat
Yellow = urgent, delay ok ~1h
Green = minor, walking wounded
📌 Expectant
Black = dead/expectant
Mass casualty → save most
✅ Do
ER: airway/shock first
Reassess often, conditions shift
🩺 Watch
Disaster ≠ daily ER logic
Tension pneumo, hemorrhage = red
📚 Triage Principles — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Triage sorts clients by severity so the most urgent are treated first. In day-to-day emergency triage, the sickest are seen first; in a mass-casualty/disaster setting the goal flips to the greatest good for the greatest number, so resources go to those most likely to survive. Memory aid in disasters: red=immediate, yellow=delayed, green=minor/walking, black=expectant/dead.
🔑
Key points
Understand these first
Conventional emergency triage treats the most critically ill or injured client first (emergent before urgent before non-urgent).
Disaster/mass-casualty triage maximizes survivors, so resources are directed to those who can be saved, not necessarily the most injured.
Disaster tags: red = immediate/life-threatening but salvageable; yellow = delayed/can wait briefly; green = minor/walking wounded; black = expectant or deceased.
Emergent (red) conditions include airway obstruction, severe hemorrhage, tension pneumothorax, shock, and chest pain with instability.
A client who can walk to a designated area (walking wounded) is generally lowest priority in a disaster.
Triage is dynamic: clients are reassessed and re-tagged as their condition changes.
✅
Nursing priorities
What to do, in order
Rapidly assess each client and assign a triage level using ABC and threat-to-life criteria.
Treat red/immediate and emergent clients first in conventional triage.
In a disaster, allocate limited resources to salvageable clients to save the most lives.
Direct walking wounded (green) to a holding area and reassess periodically.
Continuously re-triage as conditions improve or deteriorate.
🚩
Red flags — report now
Escalate immediately
Report-now: airway obstruction, uncontrolled hemorrhage, tension pneumothorax, or signs of shock require immediate (red) treatment.
Never delay a salvageable life-threat to treat a minor injury or a non-survivable (black) client in a disaster.
Do not classify a deteriorating client at their initial tag level; reassess and upgrade as needed.

What are the priority nursing interventions for Triage Principles?
Rapidly assess each client and assign a triage level using ABC and threat-to-life criteria. Treat red/immediate and emergent clients first in conventional triage. In a disaster, allocate limited resources to salvageable clients to save the most lives. Direct walking wounded (green) to a holding area and reassess periodically.
What are the warning signs of Triage Principles a nurse must report?
Report-now: airway obstruction, uncontrolled hemorrhage, tension pneumothorax, or signs of shock require immediate (red) treatment. Never delay a salvageable life-threat to treat a minor injury or a non-survivable (black) client in a disaster. Do not classify a deteriorating client at their initial tag level; reassess and upgrade as needed.
