About ICU Decoded
Last updated 30 August 2026
ICU Decoded is a bedside reference for acute medicine: 91 ICU chapters, 119 decision pathways, 113 worked ward cases and 50 calculators. It exists because the thing you need at 3am is not a textbook chapter — it is the next three steps, in order, with the dose already worked out.
Who writes it
Every pathway here was written by one person who has stood at the bedside the material describes — two years of intensive care practice, a year of emergency medicine, and ward work. That is the reason it is organised the way it is — around the sequence of decisions you actually make under time pressure, rather than around the structure of a syllabus.
It also means this is the work of a trainee, not a committee of subspecialists, and you should hold it to that standard: as a well-organised study and recall aid built from published guidelines, to be checked against your seniors, your local protocol and the primary source before it changes what you do.

How the content is made
- Sourced from published guidance. Pathways are written against current consensus standards — the Surviving Sepsis Campaign, AHA/ACC, ESC, ATLS, the Difficult Airway Society, KDIGO — and each pathway names the society behind it so you can go to the source.
- Original presentation. Flowcharts and tables are drawn from scratch. No figures or text are reproduced from copyrighted publications.
- Deterministic calculation. Infusion rates, pump conversions (mL/hr) and deficit calculations are plain arithmetic in your browser. No model, no estimate, no network call — the same inputs always produce the same output.
- Retrieval-bounded assistant. The "Ask" feature can only see passages retrieved from this site's own content, and cites the passages it used. This narrows it to material that has been written and reviewed here rather than to the open internet. It reduces invention; it does not abolish it, and answers should be read alongside the chapter they cite.
Corrections
Clinical corrections are the most useful message anyone can send, and they are acted on before anything else. If something here is wrong, out of date, or ambiguous enough to be misread at 3am, email contact@icudecodedd.com with the page and the problem.
How it is funded
Hosting, the database and the assistant all cost money to run. Two things pay for that: advertising on the free pages, and subscriptions.
Everything is free in full — every ward case, every ICU chapter, every pathway and every calculator, with no account needed. A subscription buys one thing: no advertising anywhere, plus the Ask assistant. Ads are never placed inside a calculator, next to a dose, or on anything you print.
