Defibrillator Overridable CPR-First Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defibrillators with CPR-first protocols can delay shock therapy administration, which is critical in life-threatening situations, as they require users to follow a time-consuming protocol that may not always prioritize immediate defibrillation.
Innovation Solution
A defibrillator with an overridable CPR-first protocol that allows users to quickly bypass CPR prompts and initiate shock therapy analysis or treatment, reducing delays by generating queries and analyzing responses to determine if CPR should be overridden in favor of immediate defibrillation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a CPR-first protocol is implemented in the defibrillator, then CPR treatment can be prioritized for patients who need it, but the time to administer shock therapy is delayed
Solution Approach 1:
The defibrillator protocol is made dynamic and adaptable rather than fixed. The system automatically adjusts the treatment sequence based on real-time analysis of the patient's cardiac rhythm and response to CPR, allowing it to switch between CPR-first and shock-first approaches as needed
Solution Approach 2:
The defibrillator continuously monitors the patient's response to CPR and uses this feedback to determine when to transition to shock therapy. The system analyzes rhythm changes, pulse return, and other physiological parameters to decide the optimal timing for defibrillation
2Stability of the object's composition
If the defibrillator follows a fixed CPR-first protocol, then treatment consistency is maintained, but flexibility to respond to individual patient needs is reduced
Solution Approach 1:
The protocol transitions from a static, fixed sequence to a dynamic, adaptive system that automatically adjusts based on patient response. The defibrillator continuously evaluates whether to continue CPR, initiate shock therapy, or switch between modes based on real-time physiological data
Solution Approach 2:
The system changes operational parameters based on detected patient conditions. When specific rhythm patterns or physiological responses are detected during or after CPR, the defibrillator automatically modifies the treatment parameters to prioritize shock therapy over continued CPR
3Ease of operation
If the defibrillator requires user input to bypass CPR prompts, then user control is provided, but additional time is required for protocol override
Solution Approach 1:
The defibrillator performs self-assessment and automatic decision-making about the treatment sequence. The system analyzes the patient's condition and autonomously determines whether to proceed with CPR-first or shock-first protocol, eliminating the need for user input to override the protocol

AI summary
Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator whereby a user may override a CPR-first default protocol. The method includes following steps configured in a defibrillator controller of issuing an inquiry; waiting for a response to the inquiry for a set time; ordering a CPR treatment protocol if no response is received within the set time; analyzing a response; ordering a CPR treatment protocol upon receiving a non-affirmative response to the inquiry; and ordering a shock treatment protocol upon receiving an affirmative response to the inquiry. Upon selecting a shock treatment protocol, the defibrillator performs a shock analysis under the shock treatment protocol, and either orders a CPR treatment protocol if shock treatment is not indicated by the shock analysis or provides a defibrillation shock if shock treatment is indicated by the shock analysis. Queries may be presented to a user in visual, audible, or both visual and audible format.
