IOS Impulse Oscillometry
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. IOS is almost independent of patient cooperation and can test a larger patient range than spirometry alone, from children to adult to geriatric patients.

IOS is available as a stand-alone device combined with a spirometry measurement program (MasterScreen IOS and Vyntus IOS) or as an add-on module to the MasterScreen series.
