About ICU Decoded

Last updated 23 September 2026

ICU Decoded is a bedside reference for acute medicine: 92 ICU chapters, 147 decision pathways, 87 worked ward cases, 37 ICU scores 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.
• Calculators you can trust to repeat. Infusion rates, pump rates (mL/hr) and deficits give the same result every time for the same numbers — nothing is estimated.
• Ask AI and Prescription answer only from this site. They use ICU Decoded's own chapters, cases and OPD cards — never the internet — and show which pages they used. If the site does not cover a question, they say so instead of filling the gap from elsewhere. Read every answer alongside the page it cites. How to use ICU Decoded.

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 If something here is wrong, out of date, or ambiguous enough to be misread at 3am, email contact@icudecodedd.com with the page and the problem.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.

The chapters, cases and calculators are never sold. The ICU scores, eight ICU chapters, the Cardiology cases and the emergency drug calculators are open to everyone; every other chapter, case and calculator opens free with a referral from a member, or an approved application. OPD, the outpatient drug reference, is free for your first month after you sign in; after that it comes with a subscription. A subscription buys no advertising anywhere, plus the Ask assistant, prescription writing and OPD. Ads are never placed inside a calculator, next to a dose, or on anything you print.
