Overview
EZ-IO is used in time-sensitive medical scenarios where speed and accuracy are critical. The product needed to balance clinical precision with usability so that essential information could be accessed quickly without introducing unnecessary cognitive load.
The design approach centered on simplifying complex medical content into structured, actionable flows that support real-world use in emergency conditions.
Challenge
The primary challenge was designing for a context where users have limited time, attention, and margin for error. The experience needed to accommodate dense and highly technical information while remaining clear and easy to navigate. It also had to function effectively in high-stress environments where hesitation or confusion could impact outcomes. The product ultimately needed to serve as both a reference tool and a decision-support system without overwhelming the user.

Project Initiation
The project began with defining the core use cases and identifying the most critical user paths. Early efforts focused on understanding how clinicians access and use procedural information, identifying the moments where clarity and speed are most important, and establishing a structure that supports quick scanning and decision-making. This phase created the foundation for a system that prioritizes usability under pressure.
Mapping the Experience
A comprehensive flow mapping exercise was used to define the structure of the application. Procedural steps were broken down into clear, navigable units, and relationships between content and user actions were identified. Information was organized hierarchically to support rapid access and reduce the time required to locate key details. The result was a system that allows users to move through complex workflows with minimal friction.
Approach & Process
The design process focused on reducing complexity while maintaining clinical accuracy. The experience was structured to reveal information progressively so users are not overwhelmed. Visual hierarchy was used to guide attention, and interaction patterns were kept consistent to reduce the need for relearning. Wireframes and prototypes were used to validate the clarity of the flows and ensure the experience remained intuitive across different scenarios.
To simplify use across adult and pediatric contexts, I designed a mode-selection step at launch, guiding users into context-specific flows. Wireframes and prototypes showed how each path adapted while maintaining shared navigation and visual consistency. The result was a flexible design system that could present procedural steps, videos, and product details with equal clarity and reliability.
The classification of the system varies between two types of patients, adult and pediatric. These two patient types required a careful separation of differing content within several shared categories. For example, both adult and pediatric patient could recieve a needle insertion into the proximal humerus, but the techniques were vastly different. This led to the design of a modal approach to the situation based on the user first selecting the patient classification, then which insertion site they had access to.
The following is a medium-fidelity wireframe prototype for the Teleflex EZ-IO Vascular Access System mobile application as detailed above.
Outcome and Impact
The delivered app concept gave Teleflex a polished, interactive reference tool to accompany the product launch. Rather than relying on bulky printed materials, presenters and clinicians could use the app to demonstrate, explore, and reference instructional and marketing data in real time. The modular system supports future content extension—clinical updates, new insertion techniques, or enhanced media assets—without needing a full redesign.
Retrospection
Working on EZ-IO reinforced how critical clarity is when lives are involved: every decision must help reduce ambiguity, not add to it. The design challenge was not just visual polish, but balancing trust, accessibility, and technical complexity in a way that feels seamless to a user in urgency. In the future, I’d further validate procedural flows via simulation testing and explore richer feedback cues (e.g. haptics or microanimations) to reinforce confidence during critical steps.
