原文如下:
The impulse oscillometry system (IOS)is a type of FOT but with 2 important differences; rectangular waveform impulses are applied instead of pseudorandom noise signals, and the IOS has a different set of data outputs. IOS has been used in clinical trials to examine drug effects; COPD and asthma studies have shown IOS measurements to be more sensitive than FEV1 for measuring the pulmonary effects of bronchodilator drugs. Additionally, IOS measurements can be used to sensitively diagnose obstructive lung disease. Hellincx et al. reported that IOS gives similar but not identical respiratory resistance and reactance measurements compared to FOT, underscoring that these techniques may give different results.
While there is information for FOT using pseudorandom noise generation, it is not known which IOS parameters are the most informative when assessing the severity of COPD. Importantly, we need to understand which IOS measurements are related to the degree of airflow obstruction as measured by forced expiratory volume in 1 s (FEV1), and which are related to the degree of hyperinflation measured by lung volumes. This paper describes the relationship of IOS measurements to other pulmonary function measurements in a large cohort of COPD patients (n = 94). We followed up these patients for 1 year, and then compared the changes in IOS and FEV1 measurements over 1 year.
