Spirometric and airway resistance diagnostics combined in one compact device.
Tidal breathing analysis with Impulse Oscillometry (IOS) has demonstrated to be informative and differentiated in the early detection and follow up of pulmonary diseases like asthma, COPD and idiopathic pulmonary fibrosis. Therefore IOS oscillometric airway measurements complement spirometry.
