Ventilation Strategy Display for Patient-Specific Breathing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breathing systems lack a flexible tool to provide clinicians with a clear and easily understandable feedback on the status of ongoing ventilation in relation to the chosen ventilation strategy, failing to adapt to individual patient characteristics and requiring manual adjustments based on animations that do not reflect clinical status.
Innovation Solution
A breathing apparatus with a display unit and processing unit that provides a graphical visualization combining target indications and reciprocating animations of ventilation parameters, allowing clinicians to easily understand how current ventilation relates to the desired strategy, facilitating adjustments to achieve the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional ventilation systems are used, then basic ventilation function is provided, but clear and easily understandable feedback on ventilation status relative to strategy is not provided
Solution Approach 1:
The patent uses color-coded visual indicators (e.g., green, yellow, red zones) to represent different ventilation status levels relative to the strategy targets. This allows clinicians to quickly assess ventilation compliance without interpreting complex numerical data, reducing information loss while maintaining simple presentation.
Solution Approach 2:
The patent transforms one-dimensional numerical ventilation parameters into two-dimensional graphical displays with visual indicators and target zones. This dimensional transformation provides intuitive spatial representation of ventilation status relative to strategy targets, improving comprehensibility without adding system complexity.
2Measurement precision
If detailed ventilation parameters are monitored, then comprehensive clinical status is provided, but ease of understanding from a distance is reduced
Solution Approach 1:
The patent segments comprehensive ventilation data into distinct visual components: current parameter values, target strategy ranges, and compliance indicators. This segmentation allows clinicians to quickly grasp essential information at a glance while maintaining access to detailed parameters when needed, balancing precision with ease of understanding.
Solution Approach 2:
The patent implements real-time visual feedback that automatically compares monitored ventilation parameters against strategy targets and displays compliance status. This feedback mechanism provides both detailed monitoring capability and immediate overall assessment, enabling quick understanding without sacrificing measurement precision.
3Ease of operation
If animated lung visualization is used, then ventilation process is illustrated, but clinical status information related to strategy compliance is not provided
Solution Approach 1:
The patent merges the animated lung visualization with numerical parameter displays and strategy compliance indicators into a single integrated interface. The animation provides intuitive visual understanding of the ventilation process while simultaneously displaying clinically relevant data and strategy adherence status, eliminating the information loss present in animation-only systems.
Solution Approach 2:
The patent creates a multi-functional display system where the same interface serves multiple purposes: illustrating the ventilation process through animation, monitoring clinical parameters, and assessing strategy compliance. This universal design provides both visual understanding and clinical information without requiring separate systems.
4Adaptability or versatility
If ventilation strategy targets are adjusted, then individual patient characteristics are accommodated, but ease of monitoring compliance is reduced
Solution Approach 1:
The patent allows clinicians to pre-configure ventilation strategy targets based on individual patient characteristics before initiating ventilation. The system then automatically monitors and displays compliance with these customized targets, eliminating the need for manual adjustment and monitoring setup. This preliminary configuration approach maintains adaptability while simplifying ongoing compliance monitoring.
Data Source
AI summary
A system includes a breathing apparatus, a display unit and a processing unit that is operatively connected to the display unit. The processing unit is configured to provide a graphical visualization on the display unit. The graphical visualization in turn includes a combination of a target indication for at least one ventilation related parameter of a ventilation strategy for a patient ventilated by the apparatus, and a reciprocating animation of the at least one ventilation related parameter relative the target indication. The target indication is for instance based on input of a user, such as an operator of the breathing apparatus. Alternatively, or in addition, it may be a default value stored on a memory unit being operatively connected to the processing unit. Alternatively, or in addition, the target indication is based on a measurement value of said patient's physiology or anatomy. In this manner, the system informs clinicians in a clear and easily understandable way how a current patient ventilation is related to a chosen ventilation strategy.
