Study Overview
Brief Summary
The purpose of this study is to establish the reference values of impulse oscillometry (IOS) in healthy Chinese, and compare the indices of IOS in patients with lung disease, such as chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease (ILD), and upper airway Obstruction (UAO).
