Choose a system, or set each unit individually. Your choice is remembered on this device and applied across every calculator.
A comprehensive ICU calculator suite. Choose a system below — mortality, sepsis, respiratory, neurology, haematology, GI & hepatology, or burns — then pick a score and enter values for a live, transparent result.
CritiCalc is a free, offline-capable suite of adult critical-care severity, prognosis and decision scores across seven systems — mortality, sepsis, respiratory, neurology, haematology, GI & hepatology and burns.
Every calculation runs entirely on your device: no account, no network round-trip, and no patient data are ever stored or transmitted. Once installed, the app works fully offline.
CritiCalc is a Progressive Web App — it installs straight from the browser, with no app store needed, then opens full-screen from your home screen and works offline.
✓ You're already using the installed app.
Each score implements its originally published point rules and, where applicable, mortality equations. The primary literature for every calculator is cited, with links, in the Calculators & evidence section below and in the References block at the foot of each calculator.
These tools support risk adjustment, quality benchmarking and structured communication in adult critical care. They are intended for research and benchmarking use only; they are not a bedside treatment rule and not a substitute for clinical judgement. Outputs must be interpreted in clinical context by qualified professionals and independently validated against your institution's reference implementation before any clinical use. All calculations run entirely in this browser; no data are stored or transmitted.
Every calculator with a short description and its primary references.
