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 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 کاملUsing the forced oscillation technique to evaluate bronchodilator response in healthy volunteers and in asthma patients presenting a verified positive response.
OBJECTIVE To use the forced oscillation technique to evaluate asthma patients presenting positive bronchodilator responses (confirmed through spirometry) and compare the results with those obtained in healthy individuals. METHODS The study sample consisted of 53 non-smoking volunteers: 24 healthy subjects with no history of pulmonary disease and 29 asthmatics presenting positive bronchodilato...
متن کاملAsthma diagnosis and treatment – 1007. Clinical application of forced oscillation technique for children with asthma
Background Forced oscillation technique (FOT) measures respiratory impedance by applying external pressures to the respiratory system and makes it possible to evaluate various aspect of airway physiology including small airways. MasterScreen IOS (IOS) has been widely utilized as a FOT. Recently, a new FOT, Mostgraph, has been available in Japan. Clinical experience including reference values of...
