Patient Monitor Network Baselines for Overload And Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patient monitoring devices in hospitals often experience failures due to user error or system overload, leading to delayed identification and resolution of issues, which can compromise medical care.
Innovation Solution
A system that monitors patient monitoring devices and their supporting systems via a network, gathering metrics to identify or predict issues, and notifies appropriate personnel to prevent lapses in medical care by comparing current data with baseline metrics and generating notifications for timely intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If patient monitoring devices process and exchange large amounts of data over the network, then the quality of medical care is improved through remote access to physiological parameters, but network congestion occurs reducing data transfer rate and preventing data transfer
Solution Approach 1:
The system performs preliminary actions by continuously monitoring network traffic patterns, device performance metrics, and data flow characteristics before congestion occurs. The monitoring system establishes baseline performance levels and detects deviations that predict upcoming congestion or device failures, enabling preventive maintenance and resource allocation before the actual problem impacts medical care quality.
2Reliability
If patient monitoring devices operate continuously to monitor physiological parameters, then medical care quality is improved through constant patient surveillance, but devices may hang, crash, or become non-responsive due to overload
Solution Approach 1:
The monitoring system implements continuous feedback loops that track device performance metrics including CPU utilization, memory usage, and response times. When metrics indicate approaching failure thresholds, the system generates alerts and can automatically trigger remediation actions such as device restarts or load redistribution, ensuring continuous reliable operation without manual intervention.
Solution Approach 2:
The system enables self-service capabilities where monitoring devices can automatically detect their own performance degradation, diagnose the cause of hangs or crashes, and execute self-recovery procedures such as restarting services or clearing memory buffers, reducing the need for manual technician intervention and maintaining continuous patient monitoring.
3Difficulty of detecting and measuring
If clinicians manually detect and notify technicians of device failures, then issue identification is achieved, but resolution is delayed by hours or days affecting medical care
Solution Approach 1:
The system implements automated feedback mechanisms where monitoring software continuously receives performance data from patient monitoring devices, automatically analyzes the data for failure patterns, and immediately notifies appropriate technicians through electronic alerting systems. This closed-loop feedback eliminates manual detection delays and ensures rapid response to device failures, maintaining continuous medical care quality.

AI summary
Systems and methods for monitoring physiological monitoring systems are described herein. A communication interface module can be configured to receive from a physiological monitoring system first data based on a snapshot taken of a status of the physiological monitoring system at a first time. A memory module can be configured to store the first data and a baseline associated with the physiological monitoring system. A processor module can be configured to compare the first data with the baseline and to generate a notification if the first data deviates from the baseline by a predetermined amount. A display module can be configured to display a physical location of a plurality of physiological monitoring systems and display the notification.
