Find spirometric and airway resistance diagnostics in one compact device
Large patient range
Almost independent of patient cooperation, IOS can test a larger patient age range than spirometry alone.
It helps detect pulmonary obstruction early, measuring impedance indicative of central and peripheral airway resistance.
The device can assess and differentiate airway function under quiet breathing conditions.
Stand-alone or integrated design
IOS can be used alone or integrated with the Vmax® or MasterScreen™ product lines.
It textually guides technologists during the test and helps automatically classify and interpret test results.
Bronchial provocation monitoring
The device provides the objective response of an airway tone to drug therapy even when FEV1 cannot.
