VentilO
Clinical maths, made legible
VentilO helps healthcare professionals set controlled protective ventilation: predicted body weight, initial settings, the impact of instrumental dead space, and the documentation behind each recommendation. The audience is intensivists, respiratory therapists and anaesthetists — people reading it in a hurry, in three languages.
01 — The challenge
Dense clinical calculation, on a screen someone reads standing up.
Every screen has to hold a lot at once: patient parameters, current ventilator settings, computed outputs, reference tables and the interpretation that tells the clinician what to change. Put it in a normal marketing layout and it becomes a wall of numbers nobody trusts under pressure.
It also has to work in French, English and Spanish, and behave the same on a phone in a unit as on a workstation.
The design problem was not decoration. It was making a calculation readable at a glance.

02 — Our approach
Group the inputs, isolate the outputs, and label every number.
Each module follows one numbered sequence — patient parameters, current settings, computed configuration, interpretation — so a user always knows which step they are on. Inputs sit in compact grouped controls; every computed value gets its own outlined card with the unit spelled out, and an in-line "learn more" for the clinician who wants the reasoning.
Reference tables are colour-banded rather than paragraph-explained, so the right row can be found without reading. The documentation lives inside the app as a grid of direct questions instead of a PDF, and the credits page carries the authors, collaborators and funding institutions in full — in a clinical tool, provenance is part of the product.
The whole thing is a responsive web build with a language switch on every page and links to the companion iOS and Android apps from the access screen.
Working with Web Tonic has been a fantastic experience from start to finish. Their team took the time to understand our business goals and delivered exactly what they promised. Communication was excellent, and we've already seen a noticeable improvement in our online visibility. Highly recommended!
