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 کاملExpression of bronchodilator response using forced oscillation technique measurements: absolute versus relative.
We refer to the recent study by OOSTVEEN et al. [1] on bronchodilator response in 4-yr-old children with different wheezing phenotypes. The forced oscillation technique is particularly suited to 2–7-yr-old children, and its suitability to assess bronchodilator responsiveness is still being investigated. Thus, the study is of great clinical relevance and, though of a narrow age range, is a welco...
متن کاملForced oscillation technique: from theory to clinical applications.
The forced oscillation technique (FOT) allows the noninvasive assessment of the mechanical properties of the respiratory system. Given that the technique does not require patient cooperation, it is suitable for the routine evaluation of respiratory function in a variety of clinical applications. In this paper, the rationale and the most conventional equipment and data processing of the techniqu...
متن کاملBronchial 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 کاملUsing the forced oscillation technique to evaluate respiratory resistance in individuals with silicosis.
OBJECTIVE To evaluate the resistance values obtained through the use of the forced oscillation technique in patients with varying degrees of airway obstruction resulting from silicosis. METHODS A total of 40 never-smoking volunteers were analyzed: 10 were healthy subjects with no history of pulmonary disease or silica exposure, and 30 had silicosis. The forced oscillation technique was used t...
