Comparing Ultrasonic and Conventional Spirometry in Chronic Respiratory Disease

A Comparative Study of Ultrasonic and Conventional Spirometers in Patients With Chronic Respiratory Diseases

Sponsor

Fu Jen Catholic University

Enrollment

100 participants

Start Date

Jun 29, 2026

Study Type

INTERVENTIONAL

Conditions

Chronic Obstructive Pulmonary Disease (COPD)Spirometry

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

DIAGNOSTIC_TESTSpirometer

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.
