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

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?

About this study

This study is a cross-sectional study. COPD patients aged 40 years or older will be included. Peak inspiratory flow rate (PIFR) will be assessed using In-check DIAL as the standard tool. PIFR will be tested in each patient using Accuhaler tester, Ellipta tester and Turbutester.
