Pictogram Display for Ventilator Status Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current critical care ventilators provide a vast amount of information that can be overwhelming for clinicians, making it difficult to quickly assess a patient's ventilatory status without physically approaching the ventilator and reading specific data.
Innovation Solution
A pictogram-based display system that uses color-coded visual indicators to convey patient status information, including overall and category-specific ventilatory parameters, allowing for a concise and easily understandable assessment from a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed numerical and textual ventilatory data is displayed, then complete patient status information is provided, but the display becomes overwhelming and difficult to quickly assess
Solution Approach 1:
The display is segmented into multiple categories (ventilation, oxygenation, gas exchange, lung protection, weaning) with each category containing relevant parameters. This segmentation allows clinicians to quickly identify and assess specific areas of concern without being overwhelmed by all data at once, while maintaining complete information availability through the structured organization.
Solution Approach 2:
Color-coded indicators are used to represent different patient status levels within each category. Color changes provide immediate visual feedback about patient condition without requiring clinicians to read detailed numerical values, enabling quick assessment while preserving complete data information through the color-encoding system.
2Loss of information
If detailed numerical data is displayed, then complete ventilatory parameters are provided, but the display cannot be easily viewed from a distance
Solution Approach 1:
Large, color-coded visual indicators are displayed that can be clearly seen from a distance. The color-encoding system conveys detailed parameter information through visual intensity and color variation, allowing clinicians to assess patient status without approaching the display closely, while maintaining complete parameter information through the color-encoding.
Solution Approach 2:
The display transitions from traditional text-based information presentation to a visual dimension using color-coded indicators. This dimensional change allows detailed parameter information to be conveyed through visual perception rather than textual reading, enabling distance viewing while preserving complete data through the visual encoding system.
3Ease of operation
If a pictogram with condensed information is displayed, then quick assessment is enabled, but detailed numerical data is not immediately visible
Solution Approach 1:
The pictogram is segmented into multiple categories with color-coded indicators that provide condensed overview information. Each segment can be quickly assessed at a glance, while the segmented structure allows detailed numerical data to be accessed by category when needed, maintaining both quick assessment capability and detailed information availability.
Solution Approach 2:
The color-coded pictogram serves as an intermediary between the detailed numerical data and the clinician's quick assessment need. The color-encoding system translates complex numerical information into intuitive visual indicators that enable rapid evaluation while preserving the ability to access detailed data through the structured category organization.
4Loss of information
If traditional text-based display is used, then complete information is provided, but the display requires physical approach to read
Solution Approach 1:
The display uses large color-coded visual indicators that convey complete patient status information through visual perception alone. The color-encoding system provides detailed parameter information that can be read and interpreted from a distance without requiring physical approach to the display, while maintaining complete information through the visual encoding.
Solution Approach 2:
The traditional mechanical approach of requiring physical proximity to read text-based information is replaced with an optical/visual system. Color-coded indicators provide complete information through visual perception that works effectively at a distance, eliminating the need for mechanical approach to the display while preserving complete data accessibility.
Data Source
AI summary
A system and method for displaying the status of a patient on ventilation is disclosed including a ventilator system configured to provide mechanical ventilation to a patient and a display device operatively associated with the ventilator system. The display device is configured to display a user interface including a pictogram having patient status information related to the ventilator system. The pictogram includes a central section configured to display patient status information relating to an overall status of the patient and at least one group section configured to display patient status information relating to a particular category of ventilatory status parameters.
