Medical Display Control for Prioritized Vital Sign Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern medical displays often provide information overload with numerous physiological parameters, making it difficult for clinicians to efficiently process and respond to vital signs data.
Innovation Solution
A method for controlling displays by generating an information signal that determines a total quantity-of-information score, prioritizing subsets of physiological parameters based on clinical importance, and generating a display control signal to selectively display or hide information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all physiological parameters are displayed on the medical display, then the completeness of information is improved, but the cognitive load on clinicians increases and processing efficiency deteriorates
Solution Approach 1:
The patent segments the displayed information by dividing physiological parameters into priority and non-priority subsets. The display control signal selectively displays only the priority subset of parameters, while suppressing the non-priority subset. This segmentation allows complete information to be available in the information signal while only presenting essential information on the display, thereby maintaining information completeness while improving processing efficiency.
Solution Approach 2:
The patent applies partial action by displaying only a portion (the priority subset) of the available physiological parameters rather than all parameters. The display control signal is generated to show only the necessary subset of information, which is sufficient for clinical decision-making without presenting the full set of data, thus reducing cognitive load while maintaining adequate information provision.
2Adaptability or versatility
If multiple physiological parameters are displayed simultaneously, then the overview capability is improved, but the complexity of information processing increases
Solution Approach 1:
The patent extracts and separates the essential information from the complete set of physiological parameters by determining a priority subset based on clinical importance. The display control signal is generated to display only this extracted priority subset, removing unnecessary parameters from the display. This extraction maintains the overview capability by showing the most critical parameters while reducing information processing complexity by eliminating redundant data from the visual presentation.
3Reliability
If comprehensive physiological data is presented, then the clinical accuracy is improved, but the time required to process and interpret the data increases
Solution Approach 1:
The patent applies preliminary action by pre-determining the priority subset of physiological parameters before display. The system proactively identifies and selects the most clinically important parameters in advance, generating a display control signal that presents only this prioritized subset. This preliminary sorting and selection ensures that the most accurate and relevant information is immediately available to clinicians without requiring them to process comprehensive data sets, thereby maintaining clinical accuracy while reducing data processing time.

AI summary
Proposed concepts thus aim to provide schemes, solutions, concepts, designs, methods and systems pertaining to controlling a display. In particular, embodiments aim to provide a method for controlling a display by generating an information signal which describes many physiological parameters and then generating a display control signal which only displays a subset of the physiological parameters included in the information signal (e.g., which are deemed to be of more clinical importance than the others).
