Asthma 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...
متن کاملApplication of Single-Frequency Time-Space Filtering Technique for Seismic Ground Roll and Random Noise Attenuation
Time-frequency filtering is an acceptable technique for attenuating noise in 2-D (time-space) and 3-D (time-space-space) reflection seismic data. The common approach for this purpose is transforming each seismic signal from 1-D time domain to a 2-D time-frequency domain and then denoising the signal by a designed filter and finally transforming back the filtered signal to original time domain. ...
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 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...
