Precedence-Based Parameter Source Selection for Patient Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient monitoring systems face challenges in managing multiple sources of physiologic parameters, such as determining which heart rate to display or include in alerts, especially when primary sources are not available or disconnected.
Innovation Solution
A mobile patient monitor interface that allows users to assign precedence orders to parameter sources, ensuring that alerts and displays are initiated from the first existing source, even if the primary source is unavailable, by receiving input expressions for multiple parameter sources and modifying their precedence order.

1Reliability
If multiple parameter sources are connected to a patient, then the system can provide backup data sources, but it becomes difficult to determine which source to use for displays and alerts
Solution Approach 1:
The system performs preliminary action by automatically establishing a precedence order among multiple parameter sources before conflicts arise. The interface allows users to pre-configure which devices should take priority for specific parameters, so when the primary source becomes unavailable, the system can immediately switch to the predetermined secondary source without requiring real-time decision-making or complex conflict resolution algorithms.
2Ease of operation
If the system automatically selects parameter sources, then operation is simplified, but the selection may not always be correct for clinical needs
Solution Approach 1:
The system incorporates feedback mechanisms that allow clinicians to review and adjust the automatically determined parameter sources. The interface displays which devices are currently being used for each parameter and provides easy controls for clinicians to modify the precedence order based on clinical judgment, ensuring that the system adapts to specific patient needs while maintaining operational simplicity.

AI summary
A method for automating physiologic alerts with precedence order includes receiving at a mobile patient monitor interface, a first input expression indicative of a first parameter source for first patient parameters from a first medical device from a user. The method further includes receiving, at the mobile patient monitor interface, a second input expression indicative of a second parameter source for second patient parameters from a second medical device from a user. The method further includes modifying, at the mobile patient monitor interface, a precedence order of the first parameter source and the second parameter source. The method further includes evaluating, at the mobile patient monitor interface, a complex expression of the first patient parameters and the second patient parameters based on the precedence order to initiate display of at least one parameter, derived parameter, trend, or alert on a remote device.
