Research progress in the application of impulse oscillometry and fractional exhaled nitric oxide in idiopathic pulmonary fibrosis / 中国医师杂志

Impulse oscillometry (IOS) and exhaled nitric oxide fraction determination (FeNO) are two detection methods to evaluate lung function, which can provide important functional information not captured in standardized lung function tests. These two methods may be promising disease assessment and detection tools for idiopathic pulmonary fibrosis (IPF). Therefore, it is necessary to standardize IOS and FeNO methods. This paper reviews the research progress of IOS and FeNO in IPF, and discusses the limitations of these two detection methods and their application value in IPF.
