Relationships 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 کاملExercise induced changes in spirometry and impulse oscillometry measurements in persistent allergic rhinitis.
The link between allergic rhinitis and asthma is well known. Bronchial hyperreactivity (BHR) may be present in rhinitis. The present study was aimed to compare airway responses in patients with rhinitis symptoms alone following exercise challenge, and to determine relationship of two different respiratory function tests.98 subjects with rhinitis were investigated by spirometry and impulse oscil...

متن کاملA Comparison of Impulse Oscillometry and Spirometry Values in Patients with Gastroesophageal Reflux Disease
BACKGROUND The relationship between gastroesophageal reflux (GERD) and airway diseases is still a matter of debate. Oscillometry is an objective, independent tool for the evaluation of airway resistance. The main purpose of this study is to compare spirometry and oscillometry results before and after treatment by a proton pump inhibitor (PPI) in a group of GERD patients who have no respiratory ...
