No results posted yet for this study

Summary

A classic methacholine challenge test is considered positive when forced expiratory volumen after one second (FEV1) decrease 20%. Impulse oscillometry (IOS) measures airway resistance and reactance, and seems more sensitive to changes in small airways. In adult asthma patients, we compare methacholine challenge test using both FEV1 and IOS.
