Vyntus IOS – the result of 25 years experience in Impulse Oscillometry

Tidal breathing analysis with Impulse Oscillometry (IOS) has proven to be an informative and meaningful tool used 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, adult and geriatric patients.

IOS enhances your diagnostic testing
  • Spirometric and airway resistance diag nostics in one device.
  • Assessment and differentiation of airway function under quiet breathing conditions.
  • Allows testing children < 5 years of age.
  • Automated Quality Management System for best results with multitrial concept
  • Sensitive and early detection of pulmonary obstruction.
  • Allows differentiation of central and peripheral airways by measuring airway resistance and reactance at multiple frequencies.
  • More sensitive in detecting response to drug therapy than FEV1alone.
  • Excellent for bronchial provocation monitoring.
  • Classification of small airway severity and interpretation of test results.

More than 4600 IOS users – countless studies published

The experts found that…
  • Impulse oscillometry and plethysmography should be considered the preferred techniques for measuring bronchodilation in COPD Clinical Trials
  • Several forced oscillation measures are more accurate and sensitive for detecting bronchodilator response than FEV(1)in patients with asthma
  • Airway resistance measured by IOS during methacholine challenge correlates better with asthma symptoms than traditional spirometric measures implying a higher sensitivity index
  • Impulse oscillometry provides an effective measure of lung dysfunction in 4-year old children at risk for persistent asthma
  • Spirometry underestimated the prevalence of lung function abnormalities in comparison to forced oscillation

How does it work?

The oscillations of the multi-frequency measurement signal penetrate the respiration tract at varying depths. Whereas 20 Hz signals are absorbed (shunted)in the larg e airways, 5 Hz oscillations penetrate the entire lung. Thus, the respiratory resistance Rrs of the large airways can be differentiated from the lung reactance Xrs of the small airways.
