Solution Overview

Problem

Current sudden cardiac arrest response systems face challenges in effectively guiding bystanders using automated external defibrillators (AEDs) due to the lack of real-time monitoring and feedback for telecommunicators, limiting the effectiveness of CPR and AED use instructions.

Innovation Solution

Implementing an AED network server that transmits real-time defibrillator incident information to emergency call centers, enabling telecommunicators to provide more targeted guidance during cardiac arrest incidents, including the current state of the AED, patient impedance, and CPR quality feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time data transmission from AED to PSAP is implemented, then telecommunicator guidance effectiveness is improved, but system complexity and cost increase

Engineering Contradiction:

Improvetelecommunicator guidance effectivenessVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

An AED network server acts as an intermediary component between the AED and the PSAP, managing real-time data transmission and processing. This intermediary handles the complexity of data formatting, transmission protocols, and integration with existing PSAP systems, thereby improving telecommunicator guidance effectiveness without requiring direct complex integration between AED and PSAP systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If AEDs are deployed in more locations to increase availability, then access to defibrillation is improved, but cost and maintenance burden increase

Engineering Contradiction:

ImproveAED availabilityVSAvoidnumber of AEDs

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The AED network server provides multi-functional capabilities including real-time monitoring, data storage, transmission to PSAP, and remote management of multiple AEDs. This universal platform allows a single infrastructure to support numerous AED deployments across different locations, increasing AED availability without proportionally increasing maintenance burden through centralized management.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If real-time monitoring of AED usage is implemented, then CPR and AED instruction quality is improved, but data transmission requirements and system resources increase

Engineering Contradiction:

ImproveCPR and AED instruction qualityVSAvoiddata transmission resources

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system extracts and transmits only the most critical real-time data elements from AED usage, such as instruction state, patient impedance, and CPR quality metrics, rather than transmitting all possible data. This selective data extraction maintains measurement precision for quality assessment while minimizing data transmission requirements and system resource consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

System and methods for delivering defibrillator incident information to a PSAP in real-time during emergency use of an AED are described. Such information is utilized by a telecommunicator at a PSAP to provide better guidance to volunteer caregivers during potential cardiac arrest incidents. In another aspect the AED's current instruction state and optionally the time in that state is provided to the PSAP.
