Accuracy of Accuhaler Tester, Ellipta Tester and Turbutester in Patients With Chronic Obstructive Pulmonary Disease

Overview

ClinicalTrials.gov ID: NCT06346678
Lead Sponsor: Thammasat UniversityOTHER
Brief Summary: The goal of this observational study is to investigate the accuracy of Accuhaler tester, Ellipta tester and Turbutester in patients with chronic obstructive pulmonary disease (COPD). The main question it aims to answer is:

• Do Accuhaler tester, Ellipta tester, and Turbutester demonstrate comparable accuracy to the In-check DIAL for assessing inspiratory inhalation force in COPD patients?
