Development and Testing of a Data Capture Device for Use With Clinical Incentive Spirometers: Testing and Usability...

Area of Science:

• Biomedical Engineering
• Medical Device Technology
• Digital Health

Background:

• Incentive spirometers are common medical devices lacking electronic data collection capabilities.
• Limited data hinders consensus on optimal use and evidence for benefits like preventing postoperative respiratory complications.

Purpose of the Study:

• Develop and test an add-on hardware device for real-time data capture from incentive spirometers.
• Enable the collection of previously inaccessible clinical data for research and improved patient care.

Main Methods:

• Designed and built an add-on device using reflective optical sensors to track spirometer piston and bobbin.
• Calibrated sensors and developed a breath classification algorithm for accuracy.
• Tested the device's real-time functionality as a video game controller.

Main Results:

• Achieved 99-100% accuracy in sensor location detection for volume and flow.
• Demonstrated high correlation with target volumes and flow rates.
• Breath classification algorithm showed 100% sensitivity and 99% specificity; real-time operation was seamless.

Conclusions:

• An effective, reusable add-on device for incentive spirometers was developed, enabling data collection and demonstrating Internet-of-Things (IoT) potential.
• High sensor accuracy and real-time data capabilities show promise for capturing critical clinical data.
• Further research using this device can improve incentive spirometer adoption, adherence, and clinical effectiveness.
