Accuracy of Impulse Oscillometry in Airway Dysfunction
Background: The purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (IOS) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases. Methods: The study was performed prospectively in 100 patients, who complained of dyspnea as ...
متن کاملAlternative functional criteria to assess airflow-limitation reversibility in asthma.
INTRODUCTION International guidelines define significant bronchodilator response as absolute and percentage change from baseline in forced expiratory volume (FEV1) in the first second and/or forced vital capacity (FVC) ≥12% and 200 mL. However, bronchodilator effects on other lung function parameters have also been correlated to some degree of reversible airflow limitation. OBJECTIVES To dete...
متن کاملPeripheral airway impairment measured by oscillometry predicts loss of asthma control in children.
BACKGROUND We previously showed that impulse oscillometry (IOS) indices of peripheral airway function are associated with asthma control in children. However, little data exist on whether dysfunction in the peripheral airways can predict loss of asthma control. OBJECTIVE We sought to determine the utility of peripheral airway impairment, as measured by IOS, in predicting loss of asthma contro...
متن کاملImpulse oscillometry for leukotriene D4 inhalation challenge in asthma.
BACKGROUND The value of impulse oscillometry (IOS) for bronchial provocation testing is poorly defined. We investigated the positive threshold derived from the parameters and diagnostic power of IOS for asthma with the leukotriene D(4) bronchial provocation test. METHODS We enrolled 62 subjects with asthma and 21 healthy subjects. IOS was employed to perform the leukotriene D(4) bronchial pro...
