Airway narrowing measured by spirometry and impulse oscillometry following room temperature and cold temperature exercise.
STUDY OBJECTIVE The efficacy of using impulse oscillometry (IOS) as an indirect measure of airflow obstruction compared to spirometry after exercise challenges in the evaluation of exercise-induced bronchoconstriction (EIB) has not been fully appreciated. The objective was to compare airway responses following room temperature and cold temperature exercise challenges, and to compare whether IOS...
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 کاملImpulse oscillometry in comparison to spirometry in pregnant asthmatic females.
mean age of 50.7 yrs [7]. The most common histological subtypes are hybrid oncocytic (50%) and chromophobe (34%) renal cell carcinoma, while clear cell, oncocytoma and papillary renal cell cancer are less frequently found [7]. Radiographic screening is recommended, with a typical strategy involving abdominal computed tomography and/or renal ultrasound at the time of diagnosis, followed by inter...
متن کاملComparative analysis of the bronchodilator response measured by impulse oscillometry (IOS), spirometry and body plethysmography in asthmatic children.
BACKGROUND Asthma is common among young children. The assessment of respiratory resistance by the impulse oscillometry system (IOS), based on the superimposition of respiratory flow by short-time impulses, requires no patient active collaboration. AIM We evaluated the baseline repeatability and bronchodilator response of IOS indices in preschool children, their correlation with spirometry and...
متن کاملSerum Methylarginines and Spirometry-Measured Lung Function in Older Adults
RATIONALE Methylarginines are endogenous nitric oxide synthase inhibitors that have been implicated in animal models of lung disease but have not previously been examined for their association with spirometric measures of lung function in humans. OBJECTIVES This study measured serum concentrations of asymmetric and symmetric dimethylarginine in a representative sample of older community-dwell...
