ANDREA BREITLING

​​Client:  Edwards Scientific

​​​​​

The Problem:​

​​

Edwards had an early proof of concept UI for a continuous hemodynamic monitor (touchscreen), not suitable for real clinical use or market release. 

The challenge was to design a production-ready interface that supported fast, accurate clinical decision-making in critical care environments, while running in parallel with the industrial design of the catheter device. 
 

In a clinical setting, clinicians needed to monitor glucose levels and insulin delivery simultaneously and over time, often under time pressure, requiring clear and reliable information:

​

• Data needed to be presented both numerically and visually without overwhelming users

• Trends over time were difficult to interpret without clear structure

• Critical events (boluses, infusions, meals) lacked context within the timeline

• The interface did not meet expectations for medical-grade usability, clarity, or trust

• The interface needed to align with alert patterns and conventions used at the nurse’s station

​

​

My Role

​

• Served as Program Manager, overseeing budget, timeline, and resources

• Led UX and UI design from proof of concept through market-ready product

• Defined data visualization patterns for real-time and historical clinical data

• Designed interfaces that balanced numeric data with visual trends

• Worked closely with stakeholders to ensure clinical relevance and regulatory alignment

• Led and mentored the UX team, contributing directly to key design decisions

• Developed deep expertise in hemodynamic monitoring workflows and best practices

​

Outcome:

​

• Delivered a medical-grade monitoring interface ready for deployment with the catheter system

• Enabled clinicians to view current glucose values alongside historical trends in a unified display

• Integrated recommended insulin levels with the ability to adjust or override

• Introduced clear event markers for insulin, glucose, and meals to preserve context

• Improved readability, usability, and trust, supporting faster and more confident decisions

Design Deliverables

​​

• High-fidelity UI designs and system layouts

• Data visualization patterns for real-time and historical data

• Interactive prototypes for validation and refinement

• Developer-ready specifications and handoff assets
