FEV PFT system

AWRbronchial provocationforced oscillation technique

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. Features & Benefits 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. Automatic classification and interpretation of results with SentrySuite software.
