IOS Impulse Spirometry

 

 

Based on the recording of a few tidal breaths, impulse oscillometry has demonstrated to be more sensitive under resting conditions than spirometry in measuring small airways obstruction, post bronchodilator effects and bronchial hyper-responsiveness.

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.
