Bronchial responsiveness to histamine and methacholine measured with forced expirations and with the forced oscillation technique.
The objective of this study was to compare bronchial challenge tests with two substances [histamine (H) and methacholine (M)] and two methods of measuring the effect parameter FEV1 and pulmonary impedance [with the forced oscillation technique (FOT)] in order to determine which test is the shortest, and gives the least (drug) load to the patient. Furthermore, it was considered whether the resul...
متن کاملClinical Applications of Forced Oscillation Techniques (FOT) in Patients with Bronchial Asthma
BACKGROUND Forced oscillation technique (FOT) is a method to characterize the mechanical properties of the respiratory system over a wide range of frequencies. Its most important advantage is to require minimal cooperation from the subject. This study was performed to evaluate the usefulness of the FOT applications in patients with bronchial asthma by estimating the associations between asthma ...
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 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...
