Small airway dysfunction measured by impulse oscillometry is associated with exacerbations and poor symptom control in patients with asthma treated in a tertiary hospital subspecialist airways disease clinic [PDF]
Frontiers in AllergyIntroductionSmall airways dysfunction contributes to asthma pathophysiology and clinical outcomes including exacerbations and asthma control. Respiratory oscillometry is a simple, non-invasive and effort independent lung function test that provides vital

Indices of airway resistance and reactance from impulse oscillometry correlate with aerosol particle emission in different age groups [PDF]
Scientific ReportsAirborne transmission of pathogens plays a major role in the spread of infectious diseases. Aerosol particle production from the lung is thought to occur in the peripheral airways.

Impulse oscillometry bronchodilator response in preschool children
Pediatric Pulmonology, 2023 AbstractBackgroundIn preschoolers, performing an acceptable spirometry and measuring bronchodilator response (BDR) is challenging; in this context, impulse oscillometry (IOS) represents a valid alternative. However, more studies on the standardization of BDR for IOS in young children are required.ObjectiveThe objective of the study was to identify ...

Advances in Respiratory Medicine, 2019 Pulmonary function testing involves a battery of tests from the simple pulse oximetry to the cardiopulmonary exercise testing. Impulse oscillometry (IOS) is one of the newly described pulmonary function tests. It is based on the old principle of forced oscillatory technique modified and refined as per research and advances. It involves the use of sound

Role of impulse oscillometry in diagnosis and follow-up in bronchial asthma
Lung India, 2023 Background: Asthma is defined as a chronic inflammatory disorder of the airways, characterized by bronchial hyper-responsiveness and variable airflow obstruction, that is often reversible either spontaneously or with treatment.
