OBJECTIVES This retrospective study was a comparative analysis of sensitivity of impulse oscillometry and spirometry techniques for use in a mixed chronic obstructive pulmonary disease group for assessing disease severity and inhalation therapy. METHODS A total of 30 patients with mild-to-moderate chronic obstructive pulmonary disease were monitored by impulse oscillometry, followed by spirom...

OBJECTIVE To provide an overview of impulse oscillometry and its application to the evaluation of children with diseases of the airways. DATA SOURCES Medline and PubMed search, limited to English language and human disease, with keywords forced oscillation, impulse oscillometry, and asthma. STUDY SELECTIONS The opinions of the authors were used to select studies for inclusion in this review...

BACKGROUND Spirometry is used to physiologically assess patients with central airway obstruction (CAO) before and after interventional bronchoscopy, but is not always feasible in these patients, does not localize the anatomic site of obstruction, and may not correlate with the patient's functional impairment. Impulse oscillometry may overcome these limitations. We assessed the correlations betw...

OBJECTIVE To compare blood pressure measurements in newborn infants using the flush method, pulse oximetry and oscillometry according to Doppler findings. METHODS Noninvasive blood pressure measurements were made using three techniques (flush method, pulse oximetry and oscillometry) in three groups of newborns: 15 normal term infants, 16 stable preterm infants, and 14 critically ill infants. ...

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...

BACKGROUND Both impulse oscillometry and spirometry can reflect small-airway disorders. The objective of this work was to investigate the diagnostic value of impulse oscillometry and spirometry small-airway parameters and their correlation with radiology, disease severity, and sputum bacteriology in mild to moderate bronchiectasis (bronchiectasis severity index <9) and to validate these finding...

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 ...

Background: Within-breath reactance from forced oscillometry estimates resistance via its inspiratory component (Xrs,insp) and flow limitation via its expiratory component (Xrs,exp). Aim: To assess whether reactance can detect recovery from an exacerbation of chronic obstructive pulmonary disease (COPD). Method: 39 subjects with a COPD exacerbation were assessed on three occasions over 6 weeks ...
