Reference values for respiratory system impedance using impulse oscillometry in healthy preschool children
PURPOSE The normal values for lung resistance and lung capacity of children, as determined by impulse oscillometry (IOS), are different for children of different ethnicities. However, reference values there is no available reference value for Korean preschool children have yet to be determined. The aim of the present study was to determine the normal ranges of IOS parameters in Korean preschool...
متن کاملRespiratory impedance in healthy subjects: baseline values and bronchodilator response.
Because of the minimal demand for cooperation by the subject, the forced oscillation technique is increasingly employed in routine lung function testing. However, comprehensive and device-independent values of respiratory impedance at baseline and after bronchodilation have not been established for healthy adults. The aim of this multicentre study was to collect impedance data from 4 to 26 Hz i...
متن کاملReference values for respiratory system impedance by using impulse oscillometry in children aged 2-11 years.
The forced oscillation technique makes it possible to evaluate the mechanical properties of the respiratory system with a minimum of cooperation. The method is therefore especially useful in children. Impulse oscillometry (IOS) is a commercially available version of this technique. There is, as yet, limited information on reference values for IOS in children. The aim of this study was to extend...
متن کاملRelationships between impulse oscillometry, spirometry and dyspnoea in COPD.
BACKGROUND Severity of chronic obstructive pulmonary disease (COPD) is based either on symptoms/disability or lung function, which have no discernible correlation. We hypothesised that impulse oscillometry (IOS), a non-effort-dependent measure of central and peripheral airway mechanics, could correlate to dyspnoea in COPD. METHODS We analysed screening data from 57 COPD patients who had spiro...
متن کاملEvaluation of respiratory impedance in asthma and COPD by an impulse oscillation system.
OBJECTIVE The purpose of this study was to clarify the differences in physiological properties of the airways between asthma and COPD using an impulse oscillation system (IOS). PATIENTS AND METHODS Subjects comprised 95 stable COPD patients, 52 never-smoker asthma patients and 29 healthy never-smokers >60 years old, all matched for age, in whom respiratory impedance was examined by IOS. RES...
