Nerveäna Plus Nerve Monitoring System

Project Goal

Optimizing real-time nerve monitoring for surgical safety

The Nerveäna system assists surgeons in identifying and preserving motor nerves during high-risk procedures. The objective was to refine the EMGView software interface to transform complex electromyographic (EMG) data into intuitive, actionable insights that support informed decision-making in the operating room.

Objective

Redesign the touch-screen interface to improve the visualization of nerve activity, ensuring surgeons can interpret signal integrity and threshold alarms instantly without distraction.

Role

UX/UI Designer

Final Design

Real-time surgical monitoring interface

The EMGView software was redesigned with a high-contrast, modular layout to provide surgeons with instant, actionable data during high-risk procedures. The interface prioritizes critical nerve activity waveforms and threshold alerts, ensuring the surgical team can monitor patient safety at a glance without visual distraction.

Design System

Establishing a life-critical visual language

A specialized UI framework was developed to ensure the software remains legible and functional under the unique lighting and high-stress conditions of an operating room.

  • High-Contrast Interface: Utilized a dark-mode foundation with high-contrast accent colors to ensure waveforms and alerts remain visible across the room, even under bright surgical overheads.

  • Standardized Component Library: Created a library of touch-optimized controls and data visualizations that meet medical safety standards, ensuring consistency across all diagnostic screens.

  • Scalable Data Modules: Designed flexible containers for multi-channel EMG monitoring that can adapt to different surgical needs without requiring a full layout redesign.

Strategic Decisions

Streamlining the pre-surgical setup

The interface was redesigned to guide clinicians through electrode placement and channel configuration, reducing setup time and the risk of manual errors before surgery.

  • Interactive Mapping: Replaced abstract lists with anatomical diagrams for precise, procedure-specific electrode placement.
  • Rapid Configuration: Optimized the settings architecture to allow for instant channel assignment and calibration.
  • Intelligent Presets: Implemented procedure-based defaults for threshold levels, minimizing manual input during the critical pre-op window.
Challenges

Simplifying complex system architecture

Managing the vast array of settings and electrode configurations required a hierarchy that felt intuitive to a busy medical team.

Centralized Settings

Reorganized a fragmented settings menu into a unified control center, allowing users to adjust sensitive equipment parameters without losing sight of the active monitoring status.

Visual Validation

Added real-time feedback loops within the setup diagrams so clinicians can verify signal integrity and electrode connection status at a glance before moving to the next step.

Impact

Clinical validation and successful market launch

The redesign transformed a complex data-heavy system into a streamlined clinical tool,
ensuring that surgeons can focus on the patient rather than the interface.

Regulatory Compliance: Played a key role in the interface development that successfully passed rigorous FDA safety protocols and human factors usability testing.

Operational Efficiency: Streamlined the pre-op configuration process, significantly reducing the time required for medical staff to map electrodes and verify signal integrity before surgery.

Global Market Launch: Delivered a high-contrast, touch-optimized UI that anchored the successful commercial launch of the Nerveäna system, providing clear, real-time visualization for high-stakes procedures.
