Solution Overview
Problem
Current visualizations in ICU settings only display patient physiological parameters and do not show the effects of medical interventions, making it difficult for practitioners to analyze the patient's response to interventions and make informed clinical decisions.
Innovation Solution
A visualization device and method that integrates physiological parameters with the effects of medical interventions over time, using pharmacological models to predict and display the expected effects of medications and other interventions, allowing real-time and historical visualization of intervention impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current visualizations only display physiological parameters, then the display is simple and easy to interpret, but the practitioner cannot analyze patient response to interventions
Solution Approach 1:
The patent combines physiological parameter displays with intervention effect visualizations into a single integrated display. The visualization merges patient status parameters (heart rate, blood pressure, oxygen saturation) with intervention information (medication name, dose, timing, expected effect) to provide a comprehensive view of patient response to treatments.
Solution Approach 2:
The patent adds a temporal dimension by displaying expected intervention effects at specific future time points relative to when the intervention was administered. This time-based dimension allows practitioners to see not just current patient status but also projected effects of interventions, enabling better assessment of treatment response.
2Loss of information
If the visualization shows only current physiological parameters, then real-time monitoring is maintained, but historical intervention effects cannot be assessed
Solution Approach 1:
The system pre-calculates and displays expected intervention effects based on pharmacological models before the actual patient response is fully observed. This allows practitioners to have advance information about what effects are expected, enabling faster assessment when comparing actual versus expected responses.
Solution Approach 2:
The patent creates a virtual copy or model of the intervention effect trajectory using pharmacological parameters and patient characteristics. This simulated effect profile serves as a reference that can be compared against actual patient responses at any historical time point, enabling retrospective analysis without requiring re-measurement.
3Ease of operation
If the visualization displays detailed intervention effects, then clinical decision-making is improved, but the display becomes more complex and harder to interpret
Solution Approach 1:
The patent segments the intervention effect information into distinct visual elements: medication name, administered dose, timing, expected effect trajectory, and actual patient response. This segmentation allows each component to be displayed clearly and individually, making the overall complex information easier to process and interpret.
Solution Approach 2:
The patent uses color coding to represent different aspects of intervention effects and patient responses. For example, color changes can indicate the progression of expected effects over time, highlight deviations from expected trajectories, or denote different intervention types, making the visualization more intuitive and easier to interpret at a glance.
Data Source
AI summary
Some embodiments are directed to a visualization device for showing a patient status. The visualization device may compute an effect that a medical intervention is expected to have on the patient and generate a visualization representing a physiological parameter and the expected effect. The generated visualization may be displayed on a display.
