Ventilation Meter


Ventilation (assisted breathing) is performed when a patient cannot breathe by themselves. For emergency care personnel this is an essential skill, yet also a difficult one. Doing this incorrectly by underventilating or overventilating can create or worsen brain damage, or even kill the patient.
Until recently, the need for precise ventilation has been largely overlooked. Emergency care personnel currently rely on trained skill, intuition, and primitive equipment, of which the resulting treatment widely varies.
This project set out to improve patient treatment by enabling emergency medical personnel such as ambulance staff to provide precise, safe ventilation to patients. The guiding principle for the project was to create tools allowing ventilation to be delivered according to medical best practices.

Inspiration and Method

The project started with a large literature study. Ethnography followed, and by visiting emergency departments, opinion leaders, training centres, and taking part in ride-alongs all over the world, I was able to not only understand the job, but also the people: who they are and what moves them. This conversation continued throughout the project to articulate and validate the project's complexity.
My approach started broad from a service point of view and by mock-ups, role-playing, and many interactive sketches an integrated solution was achieved.


Introducing the Ventilation Meter, a new-to-the-world feedback tool to help paramedics provide artificial breathing support. The Ventilation Meter provides tailored, precise feedback both in the field and post-event via the cloud. The basic and plus models address two different target groups respectively, guiding basic and advanced emergency care personnel.
