Evaluation of impulse oscillation system: comparison with forced oscillation technique and body plethysmography.
The impulse oscillation system (IOS) has been developed recently to measure respiratory system resistance (Rrs) and reactance (Xrs) at different frequencies up to > or = 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 plethysmographic airway resistance (Raw) in 4...
متن کاملEstimation of random errors in respiratory resistance and reactance measured by the forced oscillation technique.
The forced oscillation technique (FOT) allows the measurement of respiratory resistance (Rrs) and reactance (Xrs) and their associated coherence (gamma2). To avoid unreliable data, it is usual to reject Rrs and Xrs measurements with a gamma2 <0.95. This procedure makes it difficult to obtain acceptable data at the lowest frequencies of interest. The aim of this study was to derive expressions t...
متن کاملPediatric reference values for respiratory resistance measured by forced oscillation.
OBJECTIVES To determine, in North American children, reference values for respiratory resistance measurements by the forced oscillation (Rfo) technique and to examine whether sitting height, as index of truncal length, is a better determinant of resistance, less influenced by race and gender, than standing height. DESIGN/SETTING A prospective cross-sectional study of healthy nonobese children...
متن کاملAssociation between respiratory impedance measured by forced oscillation technique and exacerbations in patients with COPD
Background It is well known that increased airflow limitation as measured by spirometry is associated with the risk of exacerbation in patients with COPD. The forced oscillation technique (FOT) is a noninvasive method used to assess respiratory impedance (resistance and reactance) with minimal patient cooperation required. The clinical utility of the FOT in assessing the risk of exacerbations o...
متن کاملOn the Respiratory Mechanics Measured by Forced Oscillation Technique in Patients with Systemic Sclerosis
BACKGROUND Pulmonary complications are the most common cause of death and morbidity in systemic sclerosis (SSc). The forced oscillation technique (FOT) offers a simple and detailed approach to investigate the mechanical properties of the respiratory system. We hypothesized that SSc may introduce changes in the resistive and reactive properties of the respiratory system, and that FOT may help th...
