Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

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.
