Emergency Dispatch Logic Tree for Vital Sign Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency medical dispatch systems lack efficient tools for consistently and accurately gathering critical information from callers during medical emergencies, leading to potential delays in response and inadequate prioritization of emergency resources.
Innovation Solution
A computer-implemented medical dispatch system that uses a logic tree of questions and diagnostic tools, such as breathing detectors, pulse check tools, and CPR compression monitors, to rapidly assess situations and provide determinant values for resource allocation, while also offering expert guidance to callers before professional help arrives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual interrogation methods are used by dispatchers, then the process is flexible and adaptable to different callers, but the consistency and accuracy of information gathering deteriorates leading to potential delays
Solution Approach 1:
The patent introduces computerized interrogation tools and decision support systems as intermediaries between the dispatcher and caller. These tools provide standardized protocols, automated vital sign calculation, and structured questioning sequences that enhance consistency and accuracy while reducing reliance on individual dispatcher expertise and variability.
Solution Approach 2:
The dispatch system is segmented into distinct functional modules including vital sign detection tools, interrogation protocols, and decision support components. This modular approach allows each component to be optimized independently while working together to improve overall information gathering accuracy without creating an overwhelming monolithic system.
2Reliability
If comprehensive medical information is gathered from callers, then the prioritization of emergency resources is improved, but the time required for interrogation increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring interrogation protocols, vital sign thresholds, and decision trees before emergencies occur. During actual dispatch, these pre-prepared structures enable rapid information gathering with automated calculations and immediate prioritization recommendations, eliminating the need for dispatchers to manually process complex medical algorithms during time-critical situations.
Solution Approach 2:
The decision support system provides real-time feedback to dispatchers during interrogation, automatically analyzing entered vital signs and caller responses to dynamically adjust questioning sequences and provide immediate prioritization guidance. This feedback mechanism ensures comprehensive information is gathered efficiently by adapting the interrogation process based on accumulating data.
3Stability of the object's composition
If standardized protocols are implemented for all emergency calls, then consistency of response is improved, but the ability to adapt to unique situation nuances deteriorates
Solution Approach 1:
The system combines standardized protocols with dynamic adaptability through decision support algorithms that automatically adjust interrogation sequences and prioritization recommendations based on the specific characteristics of each emergency situation. The standardized framework ensures consistency while the adaptive components respond to unique nuances by modifying questioning and guidance in real-time based on accumulated information.

AI summary
A system and method assists an emergency medical dispatcher in responding to emergency calls. A computer implemented emergency medical dispatch protocol includes interrogatories for a dispatcher to ask a caller to generate an appropriate response. A diagnostic tool is provided to determine a vital sign of a patient based on a timer and caller relayed information about the patient. An intervention tool is provided to administer assistance and determine a compression rate based on a timer and caller relayed information.
