Clinical Application of the Forced Oscillation Technique
Internal Medicine, 2016 The forced oscillation technique (FOT) is a noninvasive method with which to measure respiratory system resistance and reactance during tidal breathing. Recently, its clinical application has spread worldwide with the expansion of commercially available broadband frequency FOT devices, including MostGraph and Impulse Oscillometry.

Investigation of a drag reduction on a circular cylinder in rotary oscillation [PDF]
, 2001 Drag reduction in two-dimensional flow over a circular cylinder, achieved using rotary oscillation, was investigated with computational simulations. In the experiments of Tokumaru & Dimotakis (1991), this mechanism was observed to yield up to 80% drag ...

Evaluation of impulse oscillation system: comparison with forced oscillation technique and body plethysmography [PDF]
European Respiratory Journal, 2001 The impulse oscillation system (IOS) has been developed recently to measure respiratory system resistance (Rrs) and reactance (Xrs) at different frequencies up to ≥25 Hz. IOS has, however, not been validated against established techniques.This study compared IOS with the classical pseudorandom noise forced oscillation technique (FOT) and body ...

The volume-dependent Forced Oscillation Technique
IFAC-PapersOnLine, 2018 Abstract This paper describes a novel extension of the Forced Oscillation Technique (FOT), namely the volume-dependent Forced Oscillation Technique (v-FOT). This extension is based on the measurement of the respiratory impedance over the whole lung volume.

Influence of the ageing process on the resistive and reactive properties of the respiratory system
Clinics, 2009 INTRODUCTION: In an increasingly old society, the study of the respiratory system changes and new techniques dedicated to older patients are of interest in physiologic studies as well as in the diagnosis of respiratory diseases.

Forced oscilation technique and hyperinflation in COPD
Revista Portuguesa de Pneumologia, 2008 AbstractForced oscillation technique (FOT) is a simple method used to measure the mechanical impedance of the respiratory system.It can be a valuable test in poorly cooperative patients (pts) and in severe COPD.Little information exists concerning its value on hyperinflation in COPD pts.The aim of this study was to analyze the correlation (corr ...
