Digital Spirometry Coach for Home Testing Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home spirometry testing lacks real-time, comprehensive, and interactive coaching, leading to inaccurate and unreliable results due to the absence of medical professionals, and patients often perform multiple measurements, which is tiring and time-consuming.
Innovation Solution
A spirometry coaching system that includes a spirometer with detection elements, a patient interactive display, and a control unit providing real-time audio and visual instructions and feedback on breathing maneuvers, allowing patients to perform accurate and reliable tests independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spirometry testing is performed at home without a medical professional, then patient convenience and accessibility are improved, but measurement reliability and accuracy deteriorate due to lack of real-time coaching
Solution Approach 1:
A digital coach system comprising audio output devices and display screens serves as an intermediary between the patient and the spirometry device, providing real-time coaching instructions and visual feedback that replicates the role of a medical professional, thereby maintaining measurement reliability while enabling home-based testing
Solution Approach 2:
The system enables patients to perform spirometry testing independently at home by providing automated coaching through the digital coach, eliminating the need for a medical professional to be physically present while allowing patients to self-administer the test with proper guidance
2Reliability
If multiple spirometry measurements are performed to ensure accuracy, then measurement reliability is improved, but patient fatigue and time consumption increase
Solution Approach 1:
The digital coach provides real-time visual feedback through display screens showing the patient's breathing curve and performance metrics during each measurement, allowing immediate assessment of technique quality and enabling faster determination of whether additional measurements are necessary, thereby reducing unnecessary repeat tests and patient fatigue
Data Source
AI summary
A spirometry coaching system and method is described. The system includes a spirometer comprising at least one detection element, a patient interactive display, and a control unit communicatively connected to the detection element and the patient interactive display, wherein the control unit directs an audio and visual presentation of at least one test instruction on the patient interactive display, and wherein the control unit directs an audio and visual presentation of at least one test result on the patient interactive display based on a measurement received from the at least one detection element.
