The Project

EndoPAT by Itamar Medical is a non-invasive diagnostic device for Functional Vascular Health Assessment. Together we created the entire digital interface of the system: from managing patient records and the test itself to where doctors get insight about their patients and diagnose them accordingly.


The poor usability of medical devices affects patients and can cause tremendous harm and even lead to death.

Entering a wrong value might result to a x2.2 overdose.¹

In 2010 the FDA investigated the operation of fusion pumps¹. One of the findings was that the interface does not necessarily make clear which unitsof measurement (lb/kg) should be used when entering a patient’s weight.

Therefore, clarity of information and simple usability were considered top priority.

User Journeys

Operator Flow
Created to conduct tests.

Doctor Flow
Created to let doctor diagnose patients’ test results.


I produced a high fidelity wireframe at an early stage because details like hierarchy play a big role in the product.

Screens for finding patients’ existing records or creating new records.


Focusing mainly on providing the right information at the right time and giving one clear call to action to help users to progress.

Four step process bar gives the test operator constant information of the progress of the test.

Using typography to create hierarchy in information. Giving the patient’s name high priority to provide a personal experience.


Grabs the operator’s attention in case of abnormal parameters.

The interface helps the operator in case of a problem using bubbles and bright colour.


Using every design element to help make the interface as clear as possible.

Patient’s Record Creating visual hierarchy using size, typography, colours, and white space. Clickable objects have a seperate colour and look distinctly clickable for accessibilty reasons.

Karla Regular

Karla is used as a secondary typeface in capitals and as a quiet tone of voice for section titles or parameters titles. This has been done in order to make the content or data more prominent.

Open Sans Regular

Open Sans is used as a primary typeface mainly for data, content and navigation.
