Mobile Rescue App Adapts AED Control to User Proficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trained lay providers are hesitant to use automatic external defibrillators (AEDs) during medical emergencies due to intimidation and concerns about improper use, leading to delayed defibrillation, which can significantly impact patient survival rates.
Innovation Solution
A mobile device-based rescue application that assesses the user's proficiency level and provides tailored instructions and control over the AED, allowing different levels of operation, from basic CPR guidance to advanced defibrillation, with integrated ECG analysis and simulation modes to enhance user confidence and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AED controls are located on a resuscitation control box, then the device can provide professional-grade defibrillation functionality, but the interface complexity intimidates lay providers and reduces ease of operation
Solution Approach 1:
The patent introduces a mobile device (smartphone or tablet) as an intermediary between the user and the AED control box. The mobile device runs a rescue application that provides a simplified, user-friendly interface while maintaining communication with the AED through wireless or wired connection. This mediator translates complex AED functions into intuitive graphical instructions, making the system accessible to lay providers without compromising the reliability of the defibrillation functionality.
2Adaptability or versatility
If the AED provides detailed control options for different heart rhythms and shock protocols, then the device can handle various medical scenarios effectively, but the complexity increases and intimidates untrained users
Solution Approach 1:
The patent segments the AED control interface into multiple hierarchical levels. The mobile device application presents a simplified first level for lay providers that automatically manages complex decisions. Advanced users can access additional control levels through the application if needed. This segmentation allows the system to maintain full adaptability for different heart rhythms and shock protocols while presenting only the necessary complexity to each user based on their needs and training level.
3Reliability
If lay providers wait for ambulance service rather than using AED, then they avoid making potentially wrong decisions, but the delay in defibrillation significantly reduces patient survival rates
Solution Approach 1:
The mobile device application provides real-time feedback and guidance to lay providers during the resuscitation process. The system continuously monitors the AED's analysis of the patient's heart rhythm and provides step-by-step verbal and visual instructions on what actions to take next. This feedback mechanism empowers untrained users to confidently operate the AED by clearly indicating when to shock, when to perform CPR, and when to stand clear, thereby eliminating hesitation and reducing the time to first defibrillation while maintaining high reliability through expert-level decision support.
Data Source
AI summary
A system includes a processor coupled to a memory, the processor and memory configured to determine a proficiency level of a user of a rescue application based on stored data indicative of the user's proficiency level, and based on the user's proficiency level, select a level of operation for the rescue application. The rescue application is executed on a mobile device and configured to control operation of an AED. Each of multiple levels of operation for the rescue application allows the user a different degree of control over the operation of the AED. The processor and memory are configured to present, to the user, a set of instructions associated with the selected level of operation; and to enable control of the AED according to the selected levels of operation. A different set of instructions is associated with each of the multiple levels.
