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.
One numbered sequence per module
Grouped inputs, outlined outputs,
every unit spelled out.
Each of the four clinical modules runs the same numbered path: patient parameters, current settings, computed configuration, interpretation. Inputs sit in compact grouped controls, every computed value gets its own outlined card with the unit written out, and reference tables are colour-banded so the right row is found without reading a paragraph.

03 — The results
A clinical calculator that now reads like an instrument panel.
One interface serves French, English and Spanish, with a language switch on every page and links to the companion iOS and Android apps from the access screen. The same layout holds up on a phone beside a ventilator and on a workstation.
Documentation lives inside the app as a grid of direct questions rather than a downloadable PDF, and the credits page carries the authors, collaborators and funding institutions in full. In a clinical tool, provenance is part of the product.
