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...

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 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...

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 os...

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...

the impulse oscillation system (ios) measures respiratory impedance (zrs) in terms of resistance (rrs) and reactance (xrs) at multiples of 5 hz. these measurements can be used clinically to help diagnose and monitor respiratory disorders, independent of effort. there is, as yet, no information on reference values for ios in iranian adolescents. the predictive equation for resistance and impedan...

background: indian tea industry workers are exposed to various exposures at their workplace. objective: to investigate the respiratory health of indian tea industry workers. methods: we administered a respiratory questionnaire to and measured lung function in workers of 34 tea gardens and 46 tea factories. we used correlation matrices to test the association between their respiratory symptoms a...
