Simple Triage And Rapid Treatment sorts mass-casualty patients in under 60 seconds each using RPM: Respirations, Perfusion, Mental status. Training reference only — follow your agency protocol and medical direction.

Triage criterion

Reading this result: RPM checks pass (RR 24/min, perfusion adequate, follows commands), so the patient is DELAYED (YELLOW).

SIR Epidemic ModelLive

Controls

Presets

The SIR model splits a population into Susceptible, Infected, and Recovered and lets them flow between compartments. R₀ — the average number infected by one case — sets whether an outbreak grows. Vaccinating above the herd-immunity threshold 1−1/R₀ prevents an epidemic outright.

▶ Run in Python

Data Inspector

Peak infected0.0%
Total infected0.0%
Herd immunity60%

Governing equation

Reading this result: R₀ = 2.50 > 1 with only 0% immune, so infections grow into an epidemic. You would need to immunize 60% (the herd-immunity threshold 1−1/R₀) to stop it; the current effective reproduction number is 2.50.

About this simulation

The full Mass-Casualty Triage tool models a carbon cycle with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a carbon cycle?
Open this page and use the live Mass-Casualty Triage tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a carbon cycle from your own measurements.
