Comparative Study
Detection of the airway obstruction stage in asthma using impulse oscillometry system.
Although spirometry is the most common method for evaluating the airway obstruction stage in asthma patients, it is difficult to perform in some patients. The aim of this study was to evaluate whether impulse oscillometry, an easy-to-perform technique, can detect asthmatic airway obstruction stage. ⋯ IOS provides an accurate, reliable, and patient-friendly technique for classifying asthmatic airway obstruction.
