NCT06346678

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?
