Wilderness Survival Priority Triage
For multi-casualty incidents — ranks who needs attention first using a simple MARCH-based flow.
Patient inputs (set priority 1 = highest)
Click "Add patient" for each injured person. Then "Triage" to rank them.
Result
A natural placement between the calculator and the explanation.
What this solves — and what it doesn't
When more than one person is hurt, the hardest decision is order of attention. Standard wilderness triage uses MARCH (Massive bleeding, Airway, Respiration, Circulation, Hypothermia/Head) but you also weigh distance to evac and whether the patient can walk. This tool lets you enter several patients quickly and ranks them by a simplified score.
How to read the result
The output is a ranked list with each patient’s score and the inputs that contributed. Red (top of list) is the patient to treat first; green can wait.
The biggest weight goes to absent breathing and arterial bleeding — those are minutes-from-death problems. Walking patients are deferred; unconscious patients with major bleeding jump the line.
Limitations
- This is a simplified triage heuristic, not a certified protocol.
- Doesn’t model resource constraints (one rescuer, multiple patients).
- No pediatric scoring adjustments.
- If you actually face this, take a WFR or WFA course — calculators do not replace training.
Frequently asked questions
Is this medical-grade?
No. It mirrors MARCH-style thinking but uses heuristics. Real triage is taught in Wilderness First Responder courses.
What if two patients tie?
Treat the one further from evac first; moving them early matters more.
Should I call SAR before triaging?
If alone, yes — make the call first, then attend. If with multiple rescuers, parallelize: one calls, one triages.
