Use of the forced-oscillation technique to estimate spirometry values
PURPOSE Spirometry is sometimes difficult to perform in elderly patients and in those with severe respiratory distress. The forced-oscillation technique (FOT) is a simple and noninvasive method of measuring respiratory impedance. The aim of this study was to determine if FOT data reflect spirometric indices. PATIENTS AND METHODS Patients underwent both FOT and spirometry procedures prior to i...
متن کاملForced oscillation technique and spirometry in cold air provocation tests.
BACKGROUND Impedance measurements by the forced pseudo random noise oscillation technique can be used to study the mechanical characteristics of the respiratory system. The objective of this study was to analyse the changes in impedance to a cold air provocation test in patients with asthma, and to correlate these changes with those in the forced expiratory volume in one second (FEV1). METHOD...
متن کاملReferences values for forced spirometry
Selected sets of reference values for forced spirometry derived from nonsmoking, white subjects [1] show marked differences among studies [2–6] in both predicted forced vital capacity (FVC) (up to 640 mL) and predicted forced expiratory volume during the first second (FEV1) (up to 310 mL). The magnitude of the differences among reference values gives rise to potential concerns for the clinical ...
متن کاملShort-term ventilatory effects in workers exposed to fumes containing zinc oxide: comparison of forced oscillation technique with spirometry.
Following the occurrence of metal fume fever in some subjects after the installation of an electric furnace in a steel plant, a survey was undertaken to examine whether subjects exposed to fumes containing zinc oxide would exhibit a detectable impairment in ventilatory function, and whether a forced oscillation technique (FOT) was more suited for this detection than conventional spirometry. Pul...
متن کاملForced oscillation technique in the detection of smoking‐induced respiratory alterations: diagnostic accuracy and comparison with spirometry
INTRODUCTION Detection of smoking effects is of utmost importance in the prevention of cigarette-induced chronic airway obstruction. The forced oscillation technique offers a simple and detailed approach to investigate the mechanical properties of the respiratory system. However, there have been no data concerning the use of the forced oscillation technique to evaluate respiratory mechanics in ...
