Ventilator Priority Control for COPD-OSA Overlap Syndrome
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical solutions fail to simultaneously address Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA) overlap syndrome, leading to increased comorbidities and complications.
Innovation Solution
A ventilator system equipped with sensors and physical computer processors that detect OSA events and expiratory flow limitations, determine therapy parameters, and prioritize treatments by controlling a pressure generator to deliver pressurized breathable gas to the airway, addressing both conditions concurrently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate medical solutions are used for COPD and OSA, then each condition can be addressed individually, but the coexistence of both conditions cannot be adequately treated simultaneously
Solution Approach 1:
The ventilator system is designed to perform multiple functions by simultaneously detecting and treating both COPD (through expiratory flow limitation detection and treatment) and OSA (through apnea event detection and treatment). The system uses a single device with integrated sensors and control algorithms that can identify and respond to both conditions, making one device serve multiple therapeutic purposes.
Solution Approach 2:
The system dynamically adjusts treatment priorities based on real-time detection of which condition is more severe or urgent. The control algorithm continuously monitors both COPD and OSA parameters and adapts the therapy delivery to address the most critical condition at any given moment, allowing the treatment approach to change dynamically rather than being fixed.
2Adaptability or versatility
If a single medical device is designed to treat both COPD and OSA, then multi-condition treatment capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the detection and treatment functionalities for both COPD and OSA into a single integrated ventilator system. The sensors, processors, and therapy delivery mechanisms are merged into one device, eliminating the need for separate machines and reducing overall system complexity despite the increased functional requirements.
Solution Approach 2:
By designing a universal ventilator that can detect and treat multiple respiratory conditions, the system avoids the complexity of having separate specialized devices. The single device uses shared hardware components and integrated control algorithms to manage both COPD and OSA therapies.
3Reliability
If priority treatment is assigned to OSA events, then upper airway obstructions are managed more effectively, but expiratory flow limitations may receive less attention
Solution Approach 1:
The system employs dynamic priority assignment where the treatment focus shifts based on the relative severity and urgency of detected events. When OSA events are detected, the system prioritizes their treatment, but when COPD symptoms become more prominent, the priority dynamically adjusts to address expiratory flow limitations, ensuring both conditions receive appropriate attention over time.
Solution Approach 2:
The ventilator continuously monitors respiratory parameters and uses feedback from sensors to adjust treatment priorities in real-time. The system detects the presence and severity of both OSA and COPD events, then uses this feedback information to dynamically allocate therapy resources, ensuring that the most critical condition receives immediate attention while maintaining oversight of the other condition.

AI summary
The present ventilator system, for detecting and treating concurrent chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA event(s)) overlap syndrome, comprises a pressure generator for generating a pressurized flow of breathable gas for delivery to an airway of a subject; sensor(s) for generating output signals conveying information related to breathable gas parameters; and processor(s) operatively connected to the sensor(s) and the pressure generator, configured to: detect presence of OSA event(s) and/or expiratory flow limitation (EFL) in the subject based on the output signals. Responsive to detecting concurrent presence of OSA event(s) and EFL, the processors are configured to determine OSA EVENT(S) therapy parameters for treating the detected OSA event(s) in the subject; determine EFL therapy parameters for treating the detected EFL in the subject; determine a priority treatment based on a comparison between the OSA event(s) therapy parameters and the EFL therapy parameters; and control the pressure generator to deliver the determined priority treatment.
