Video-Directed CPR Guidance With Real-Time Compression Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In out-of-hospital cardiac arrests (OHCA), there is a high fatality rate due to delayed or inadequate cardiopulmonary resuscitation (CPR) performance by untrained individuals, with existing audio-guided CPR methods being challenging and ineffective for lay caregivers.
Innovation Solution
A system and method utilizing a video-directed CPR instruction system with real-time communication and monitoring, including a mobile app, wireless CPR equipment stand, and sensors to guide lay caregivers through effective CPR techniques, providing visual and audio feedback, and integrating with emergency services for seamless coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If audio-guided CPR instructions are provided to lay caregivers, then CPR guidance is provided, but the instructions are challenging and ineffective for untrained individuals to follow
Solution Approach 1:
The patent replaces audio-based guidance with a video-based system that uses a smartphone camera to capture real-time images of the patient's chest and provides visual feedback on compression quality. This substitution from auditory to visual-mechanical feedback enables untrained lay caregivers to perform CPR more effectively by showing them exactly what correct compression looks like, rather than just telling them through audio instructions.
2Reliability
If EMT response time is waited for, then professional help is provided, but the response time is delayed (7-14 minutes average, over 30 minutes in 10% of cases)
Solution Approach 1:
The patent enables preliminary action by providing immediate CPR guidance to lay caregivers at the scene of cardiac arrest, allowing them to perform effective resuscitation right away while waiting for EMT arrival. The system connects to emergency services automatically and provides real-time video feedback, ensuring that critical minutes are not lost while professional help is en route.
Solution Approach 2:
The system provides real-time feedback to caregivers about their CPR performance by analyzing video images of chest compressions and comparing them to quality standards. This immediate feedback loop allows caregivers to adjust their technique on the spot, ensuring high-quality CPR is delivered during the critical pre-arrival period without waiting for professional instruction.
3Productivity
If only 46% of OHCA receive CPR, then some patients receive immediate treatment, but 54% of Americans do not know CPR and 90% of OHCA remain fatal
Solution Approach 1:
The patent enables self-service by allowing any smartphone to function as a CPR quality monitoring device. The system uses the phone's existing camera and processing capabilities to provide real-time feedback without requiring specialized equipment or extensive training. This democratization of CPR guidance technology enables widespread adoption among lay caregivers, potentially increasing both the initiation rate and quality of CPR.
Solution Approach 2:
The system changes the parameter of CPR guidance from abstract audio instructions to concrete visual feedback by capturing images of chest compressions and providing real-time quality assessment. This parameter change from auditory to visual-modified feedback makes the technique accessible to untrained individuals and improves the likelihood of correct performance.

AI summary
The system provides a real-time video and audio communication with a 911 call center to perform effective CPR on a patient experiencing OHCA with real-time monitoring and feedback. The system includes a Mobile App that communicates with a smart phone with camera, a wireless remote-CPR equipment stand and emergency CPR kit. The mobile app will automatically send a link to a caregiver's cell phone responsive to a 911 call placed by the caregiver, to establish a secured video call via which the 911 center can guide the caregiver in performance of CPR until an ambulance arrives. This integrated description provides a comprehensive overview of the AI-driven CPR guidance system, detailing its core components, operational workflow, training processes, and scalability. By combining real-time coaching, advanced diagnostics, and EMS coordination, the system offers a groundbreaking approach to improving OHCA outcomes.
