Dynamic Waveform Tracing Layout for Central Patient Monitors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical monitoring devices inefficiently utilize display space and require manual selection/de-selection of patients, leading to suboptimal presentation and management of waveform tracings on central monitors.
Innovation Solution
Automated detection and presentation of waveform tracings on central monitors, maintaining a predetermined aspect ratio, which adjusts dynamically with connected/disconnected monitoring devices, allowing for efficient use of screen real estate and quick identification of tracing normalcy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple waveform tracings are displayed in a small area of the display screen, then the available display space is preserved for future additions, but the effective utilization of current display space is reduced
Solution Approach 1:
The system dynamically adjusts the number and arrangement of waveform tracings displayed on the screen based on the current number of active patients. When patients are added or removed, the display automatically reconfigures to optimize space utilization, transitioning from a static layout to a dynamic adaptive layout that fully utilizes available display real estate.
Solution Approach 2:
The system transitions from displaying waveform tracings in a single small area to utilizing the entire display screen by distributing tracings across multiple dimensions and regions. This allows the display to expand from a concentrated small area to a distributed full-screen arrangement, effectively using available space while maintaining information visibility.
2Ease of operation
If manual selection and de-selection of patients is required, then control over waveform presentation is maintained, but the complexity of operation increases and efficiency decreases
Solution Approach 1:
The system automatically detects when patients are connected to or disconnected from monitoring devices and autonomously updates the display to include or exclude the corresponding waveform tracings. This self-service mechanism eliminates the need for manual selection and de-selection operations, reducing operational complexity while maintaining accurate waveform presentation.
Solution Approach 2:
The system continuously monitors the status of monitoring devices and patients, receiving feedback about connections and disconnections. Based on this real-time feedback, the display automatically adjusts the waveform tracings shown, creating a closed-loop system that responds to changes without requiring manual intervention.
3Reliability
If waveform tracings are displayed without a predetermined aspect ratio, then flexibility in display arrangement is increased, but the ability to quickly identify tracing normalcy is reduced
Solution Approach 1:
The system maintains a predetermined aspect ratio for waveform tracings as a fixed parameter that does not change regardless of the number of tracings displayed. This consistent aspect ratio parameter allows clinicians to quickly and reliably assess tracing normalcy by comparing waveforms against known reference patterns, ensuring reliable clinical interpretation.
Solution Approach 2:
While the overall display layout may vary to accommodate different numbers of patients, each individual waveform tracing maintains a consistent predetermined aspect ratio. This local quality consistency ensures that the critical measurement characteristics of each tracing remain unchanged and easily interpretable, while the global display structure adapts to operational needs.

AI summary
Methods, computer systems, and computer storage media are provided for automatically populating a central monitor perspective with waveform tracings having a predetermined aspect ratio. A selection of a unit location is received, and monitoring devices connected to patients at the unit location are detected. Waveform tracings associated with the active monitoring devices are presented in a predetermined aspect ratio in the central monitor perspective. As new monitoring devices are connected to patients, or as monitoring devices are disconnected from patients, the central monitor perspective is automatically refreshed to reflect currently active waveform tracings having the predetermined aspect ratio.
