Comparing Ultrasonic and Conventional Spirometry in Chronic Respiratory Disease
Sponsor: Fu Jen Catholic University
Summary
This study compares a handheld ultrasonic spirometer with a standard hospital spirometer in adults with chronic respiratory diseases. Each participant will complete lung function tests using both devices. The study aims to determine whether the ultrasonic device provides accurate and reliable measurements for use in clinical or home settings.

Interventions
Spirometer
The handheld ultrasonic spirometry device uses acoustic flow analysis to measure FEV1, FVC, and PEF and is evaluated for accuracy compared with the conventional spirometer. Participants may perform this test either before or after the conventional spirometry test, depending on the randomized crossover sequence.
