Figure-Eight Hemodynamic GUI for Clinician Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circulatory system graphical user interfaces (GUIs) in patient monitoring are either too complex, overwhelming clinicians with excessive detail, or too simplistic, failing to effectively convey changes in a patient's hemodynamic state, particularly in intensive care units where numerous physiological parameters are measured.
Innovation Solution
A figure-eight schematic GUI is used to intuitively represent a patient's circulatory system, with loops and arc fragments conveying measured physiological parameters such as pulmonary and systemic circulation pressures, cardiac output, and vascular resistance, allowing clinicians to quickly identify issues and their impacts without needing electronic medical records or patient data management systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional numerical displays and waveforms are used to represent hemodynamic parameters, then measurement precision and data completeness are improved, but device complexity and ease of operation deteriorate due to overwhelming detail and cognitive strain on clinicians
Solution Approach 1:
The patent applies color changes to encode hemodynamic parameter states, where different colors represent different ranges or conditions of physiological parameters. This allows clinicians to quickly assess patient status through color-coded visual cues without parsing complex numerical data, thereby maintaining measurement precision while reducing GUI complexity and cognitive load.
Solution Approach 2:
The patent transforms traditional two-dimensional numerical displays into three-dimensional visual representations, such as using the size, shape, or spatial position of graphical elements to represent multiple parameters simultaneously. This dimensional transformation enables comprehensive hemodynamic assessment in a single intuitive view, reducing the complexity of presenting multiple parameters while maintaining data completeness.
2Loss of information
If detailed numerical data and waveforms are displayed, then information completeness is improved, but ease of operation deteriorates due to cognitive overload on clinicians
Solution Approach 1:
The patent merges multiple hemodynamic parameters into unified graphical representations, such as combining pressure, flow, and resistance data into single visual elements that convey the overall hemodynamic state. This consolidation maintains comprehensive information while dramatically improving ease of operation by allowing clinicians to assess multiple parameters simultaneously without cognitive overload.
Solution Approach 2:
The patent uses color-coded visual elements to represent different hemodynamic parameters and their states, enabling clinicians to quickly comprehend complex physiological information through intuitive color patterns rather than parsing numerous numerical values. This approach preserves information completeness while significantly enhancing ease of operation.
3Ease of operation
If naturalistic representation of organs is used, then ease of operation is improved through intuitive visualization, but device complexity increases due to unnecessary graphical elements and reduced information density
Solution Approach 1:
The patent segments the circulatory system into functional components represented by simplified geometric shapes, such as using circles for chambers and arcs for vessels. This segmentation maintains visual intuitiveness by preserving the topological relationships of circulatory structures while eliminating unnecessary naturalistic details, thereby reducing graphical element complexity and increasing information density.
Solution Approach 2:
The patent employs curved and circular geometric forms to represent circulatory structures, using arcs and circles to depict vessels and chambers. These simple curved shapes maintain visual intuitiveness by resembling the circular nature of blood flow paths while avoiding complex naturalistic rendering, thus reducing graphical complexity while preserving ease of operation.
4Measurement precision
If multiple hemodynamic parameters are displayed separately, then measurement precision is improved, but productivity deteriorates due to increased time required to assess patient status
Solution Approach 1:
The patent merges multiple hemodynamic parameters into integrated visual displays where related parameters are shown together in unified graphical elements. This allows clinicians to assess multiple parameters simultaneously in a single glance, dramatically improving assessment speed while maintaining the precision of individual parameter measurements through carefully designed visual encodings.

AI summary
Methods and apparatus disclosed herein relate to graphical representation of patient hemodynamic state. In various embodiments, one or more measured physiological parameters of a patient may be analyzed. Based on the analysis, a graphical user interface (GUI) may be rendered. The GUI may include a figure-eight schematic (222, 1222) that represents a circulatory system of the patient. The figure-eight schematic may include: a first loop (224, 1224) that represents pulmonary circulation of the patient; a second loop (226, 1226) that represents systemic circulation of the patient; and a central object (228, 1228) that connects the first and second loops represents a heart of the patient. In various embodiments, each of the first and second loops includes multiple arc fragments, with each arc fragment being shaped to convey one or more of the measured physiological parameters of the patient.
