Vyntus IOS Impulse Spirometry

 

...

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.

  • Almost independent of patient cooperation, IOS can test a larger patient range than spirometry alone, from children, adult and geriatric patients.
  • Assessment and differentiation of airway function under quiet breathing conditions.
  • Sensitive and early detection of pulmonary obstruction. Asthma patients may be asymptomatic with normal spirometry and still show levels of increased airway resistance. IOS measures impedance at different frequencies indicative of central and peripheral airway resistance.
  • Allows differentiation of central (proximal) airways resistance and peripheral (distal) airways resistance.
  • Bronchodilator therapy often does not reach the peripheral airways. IOS can provide objective response to drug therapy even when FEV1 can’t.
  • Monitor the effect of bronchial provocation on airway tone.
  • Automated classification and interpretation of test results.
