FVC PFT system PDD-301/so

FEVforced oscillation technique

The Forced Oscillation Technique (FOT) offers a modern and reliable but economical method for the impedance measurement of respiratory system. During test the patient is only asked to breath normally and no respiratory manoeuvre is needed. Since the test requires minimum co-operation from the patients, the FOT device is and uniquely applicable in paediatric pulmonology Measurement of the components of the airway impedance at different frequencies Determination of the resonance frequency of the airways Average calculation of Reproducible Impedance Spectra Model evaluation of Impedance Spectra Calculation of Resistance / Elastance / Inertance of the respiratory system Random induced frequencies Sequential induced frequencies Measurement modes Respiratory impedance measurement FVC measurement IVC measurement MVV measurement Measured parameters Forced Oscillation Technique Rrs Resistive component of respiratory impedance Irs Inertance of the airways Crs Compliance of the respiratory system fres Resonance frequency Forced ex and inspiration FVC - Forced Vital Capacity FEV*0.5 Forced Expiratory Volume in 0.5 second FEV*1.0 Forced Expiratory Volume in 1.0 second FEV*0.5/IVC Ration of FEV*0.5 and IVC in % FEV*0.5/FVC Ration of FEV*0.5 and FVC in % FEV*1.0/IVC Ration of FEV*1.0 and IVC in % FEV*1.0/FVC Ration of FEV*1.0 and FVC in % PEF - Peak Expiratory Flow FEF*25-75% Forced mid-Expiratory Flow rate FEF*75% Forced Expiratory Flow at 75% lung volume FEF*50% Forced Expiratory Flow at 50% lung volume FEF*25% Forced Expiratory Flow at 25% lung volume
