Fishbone Vital Sign Display Layout for Compact Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient care systems face challenges in consistently and efficiently displaying patient vital sign information, leading to slower data interpretation and decreased accuracy due to inconsistent layouts and excessive use of display space.
Innovation Solution
A fishbone pattern with standardized compartments is used to display vital signs, including respiratory rate, heart rate, blood oxygen saturation, temperature, and blood pressure, eliminating the need for labels and optimizing space, while incorporating a calculated early detection index or warning score in a consistent and simplified layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional vital sign display layouts are used, then all vital sign information can be displayed, but the display consumes excessive space and lacks consistency across different monitors
Solution Approach 1:
The display is segmented into a fishbone structure with five distinct compartments, each dedicated to a specific vital sign parameter. This segmentation organizes information efficiently within limited display space while maintaining consistent positioning across different monitors, resolving the contradiction between space utilization and readability.
Solution Approach 2:
The layout transitions from traditional horizontal or grid-based arrangements to a vertical fishbone structure, utilizing the vertical dimension more effectively. This dimensional change allows compact presentation of all vital signs without sacrificing readability, as each parameter occupies a dedicated vertical compartment.
2Productivity
If more information is displayed for each patient, then clinical productivity improves, but the display becomes more complex and harder to read
Solution Approach 1:
By segmenting the display into five specialized compartments (respiratory rate, heart rate, blood pressure, temperature, SpO2), the system presents comprehensive vital sign information in an organized manner. This segmentation enables clinicians to quickly locate and interpret all necessary parameters without being overwhelmed by display complexity.
Solution Approach 2:
Each compartment in the fishbone diagram is optimized for its specific vital sign type, with appropriate formatting and positioning. This local optimization ensures that each parameter is displayed with the quality and detail needed for clinical decision-making, while the overall structure remains simple and consistent.
3Adaptability or versatility
If vital signs are displayed in different locations on different monitors, then flexibility is maintained, but consistency and quick access to information are compromised
Solution Approach 1:
The fishbone diagram provides a universal layout template that can be implemented across all patient monitors regardless of size or model. This universal structure ensures that vital signs are always displayed in the same relative positions, enabling clinicians to quickly locate information without relearning display layouts, while still adapting to different monitor specifications.
Solution Approach 2:
The layout pre-assigns specific compartments to specific vital signs before data is displayed. This preliminary organization means that when vital sign data arrives, it is immediately placed in the correct predetermined location, eliminating the need for dynamic repositioning and ensuring consistent, quick access to all parameters.

AI summary
A patient's vital sign measurements are displayed in a fishbone diagram defined by a horizontal line with a vertical line crossing it to form four compartments. The patient's respiratory rate and heart rate are displayed in assigned compartments above the horizontal line separated by the vertical line and the patient's oxygen saturation (SpO2) and temperature are displayed in assigned compartments below the horizontal line separated by vertical lines. Two diverging horizontal lines form a sideways “V” are connected with the right hand side of the horizontal line to define a fifth compartment in which the patient's blood pressure is displayed.
