Responder Network for Dynamic AED Deployment and Volunteer Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite the increasing availability of automated external defibrillators (AEDs), many locations lack on-site AEDs during cardiac arrest incidents due to high costs, and bystanders often fail to use them due to unawareness or intimidation, leading to delayed response times and reduced survival rates.
Innovation Solution
A public responder network system that includes AEDs with connectivity features and volunteer responders, utilizing a server to query and alert nearby functional AEDs and trained individuals, facilitating rapid deployment through mobile apps and interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If AEDs are deployed in more locations to improve availability, then the coverage area increases, but the cost increases
Solution Approach 1:
The AED system is designed to serve multiple functions: it can be placed in fixed locations (lockers, cabinets) and mobile locations (vehicles, portable cases). The same device can serve different communities and locations, maximizing the utility of each AED unit and reducing the total number needed to achieve broad coverage.
Solution Approach 2:
The system transitions from static AED placement to dynamic, mobile AED deployment. AEDs can be moved between locations based on demand, incident reports, and community needs. This dynamic approach allows a smaller number of AEDs to cover a larger area over time, reducing overall cost while maintaining availability.
2Loss of time
If bystanders are provided with AEDs to use, then the response time decreases, but the difficulty of operation increases due to intimidation
Solution Approach 1:
The AED system provides self-service through automated voice guidance and visual displays that walk the user through each step of the process. The device automatically analyzes the patient's rhythm and determines whether a shock is needed, eliminating the need for the bystander to make complex medical decisions. This reduces intimidation while maintaining rapid response.
Solution Approach 2:
The AED acts as an intermediary between the untrained bystander and the complex medical task of defibrillation. The device translates the bystander's simple actions (pressing buttons, following prompts) into sophisticated medical interventions, bridging the gap between layperson capability and professional-level treatment.
3Reliability
If AEDs are placed in fixed locations, then the device reliability increases, but the accessibility decreases
Solution Approach 1:
The AED system is segmented into separate functional components: the core defibrillator unit, the housing/cabinet, and the power supply. This allows the reliable core unit to be separated from the fixed installation, enabling the AED to be placed in mobile containers or vehicles while maintaining the reliability of the proven defibrillator component.
Solution Approach 2:
The system transitions from static, fixed-location AEDs to dynamic, mobile AED deployment. AEDs can be transported to incidents or positioned in vehicles that patrol communities, combining the reliability of established devices with the accessibility of mobile deployment. The AEDs can be quickly deployed to multiple locations based on community needs.
