Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clinical decision-making for patients at risk of shock, particularly cardiogenic shock, is hindered by the lack of integrated systems that collect and analyze comprehensive data to provide timely treatment recommendations, leading to high mortality rates due to the urgency and complexity of managing dynamic patient measurements.
Innovation Solution
A shock detection and management system that integrates data from multiple sensors and devices, applies automated rules to generate treatment recommendations with confidence levels, and allows clinicians to accept or reject suggestions based on evolving patient conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive hemodynamic measurements are collected and analyzed to provide timely treatment recommendations, then treatment accuracy and patient outcomes are improved, but system complexity and data management burden increase
Solution Approach 1:
The system segments the complex decision-making process into distinct modules: data collection from multiple sensors, automated rule-based analysis, confidence level calculation, and clinician review. This segmentation allows each component to handle specific aspects of shock detection independently, reducing overall system complexity while maintaining comprehensive monitoring capabilities.
Solution Approach 2:
The patent introduces an intermediary rule-based analysis system that mediates between raw hemodynamic data and treatment decisions. This intermediary layer automatically processes complex measurements and generates actionable recommendations with confidence levels, reducing the cognitive burden on clinicians while improving decision accuracy.
2Ease of operation
If manual collection and analysis of multiple measurements is performed by clinicians, then treatment decisions can be made with current available data, but time for analysis and decision-making is consumed
Solution Approach 1:
The system performs preliminary analysis of hemodynamic data automatically using predefined rules and algorithms. Treatment recommendations with confidence levels are generated in advance of clinician review, so that when clinicians need to make decisions, the analytical work is already completed, significantly reducing their time burden.
Solution Approach 2:
The automated system performs self-service analysis of patient data without requiring clinician intervention for each measurement. The rule-based engine continuously monitors hemodynamic parameters and generates recommendations autonomously, allowing clinicians to focus on higher-level decision-making and patient care.
3Measurement precision
If right-heart catheterization is performed to obtain critical diagnostic information, then hemodynamic state can be accurately assessed, but procedure complexity and patient risk increase
Solution Approach 1:
The system achieves multi-functionality by deriving comprehensive hemodynamic assessments from multiple non-invasive and minimally invasive measurements. By integrating data from various sensors and applying unified analysis rules, the system provides right-heart catheterization-level diagnostic information through less invasive means, reducing procedure complexity and patient risk.
4Reliability
If comprehensive data from multiple sensors is integrated and analyzed, then treatment recommendations become more evidence-based, but data management and processing requirements increase
Solution Approach 1:
The system extracts only the critical hemodynamic parameters and key features necessary for shock detection from the comprehensive sensor data. By filtering and selecting only the most relevant measurements, the system reduces data volume for analysis while maintaining the evidence-based quality of recommendations through focused examination of essential physiological parameters.

AI summary
A clinical care system that integrates and analyzes patient data and applies rules to recommend potential treatments. A potential application is detection and management of shock, using hemodynamic data collected from devices such as a right heart catheter. The system may calculate confidence levels for each rule and present high-ranked treatment options to clinicians along with their confidence levels. Confidence levels for treatments may change continuously as a patient's condition evolves. For shock, features extracted from measured data may include for example a cardiac index (cardiac output divided by patient body surface area), systemic vascular resistance, and mean arterial pressure; treatment recommendations derived from these (and other) features may include administration of various medications such as epinephrine and vasopressin, installation of a ventricular assist device, transfusion, and volume resuscitation. Machine learning may be used to match recommendations to current clinical practice, or to optimize patient outcomes.
