... that the reference equations overestimate/underestimate the outcome dispersion [ 23 ]. FOT, forced oscillation technique. Measurements of lung mechanics are fundamental for the diagnosis, prognosis, and follow-up of many respiratory diseases [ 1 ]. Spirometry is the gold standard for evaluating pulmonary...

...Gerusa Maritimo da Costa; Alvaro Camilo Dias Faria; Ana Maria Gonçalves Tavares Di Mango; Agnaldo José Lopes; Pedro Lopes de Melo Background: Recent studies suggested that the bronchodilator response depends on airway obstruction. The forced oscillation technique (FOT) may help improve our...

...Alvaro C.D. Faria; Agnaldo J. Lopes; José M. Jansen; Pedro L. Melo Background: The forced oscillation technique (FOT) is a promising method for providing a detailed analysis of respiratory mechanics during spontaneous breathing. There is limited data about the use of FOT in patients...

... efforts are not sensitive enough. By measuring esophageal pressure even small disturbances can be detected, but the esophageal gauge may disturb sleep. We conclude that other, less invasive methods like measurements of impedance by forced oscillation technique, or flattening of the inspiratory flow...

...M. Quaedvlieg; E.F.M. Wouters In 10 asymptomatic young smokers and 15 non-smokers, total respiratory impedance was determined by means of the forced oscillation technique in a frequency range between 4 and 52 Hz under basal conditions, and after isocapnic hyperventilation with cold air. In non...

...C.E.J. Cuijpers; G. Wesseling; G.M.H. Swaen; E.F.M. Wouters With the use of the forced oscillation technique, respiratory input impedance was measured in 371 healthy children, aged 5-12 years. How impedance values varied with height (age) and gender and to what extent negative frequency dependence...

...M. Cauberghs; K.P. Van de Woestijne The forced oscillation technique developed by Korn et al. in 1979 (Siregnost FD 5) overestimates the measured resistances by about 20% in the range of resistance values met in healthy subjects and in patients. This is due to an overestimation of the impedance...

...W. Randerath; K. Parys; D. Lehmann; B. Sanner; F. Feldmeyer; K.-H. Rühle Background: Measurement of impedance using forced oscillation technique is a sensitive means of detecting airway obstructions, including the obstructive sleep apnea syndrome (OSAS). Objective: The present study was conducted...

...S. Reisch; J. Daniuk; H. Steltner; K.-H. Rühle; J. Timmer; J. Guttmann Background: The forced oscillation technique (FOT) allows analysis of the upper airway impedance and, hence, detection of obstructive sleep apnea. Objective: To evaluate FOT with respect to sensitivity and to specificity...
