The Determination of Lung Function Using Impulse Oscillometry and Spirometry
… data for individuals 18-22 years old using oscillometry by comparing the values to spirometry. Oscillometry is a less invasive procedure for respiratory testing than spirometry testing. One hundred and forty-two participants completed self-assessment questionnaires, along with body …

From sneeze to wheeze: Non-invasive studies on asthma and rhinitis
… such as induced sputum, exhaled nitric oxide and impulse oscillometry in addition to bronchial provocation tests we found signs indicating a higher degree of peripheral airway involvement in the asthmatic group. The transition from allergic rhinitis to clinical asthma is probably a gradual one, …

Lung function in smokers - Aspects on COPD diagnosis and associations to atherosclerosis and alcohol consumption
… promising method for early diagnosis of COPD is Impulse Oscillometry System (IOS). Reduced lung function (measured with spirometry) and COPD is associated with cardiovascular disease in a not completely understood way. Smoking is associated with elevated alcohol consumption, but the potential …

Sensory-Mechanical Responses to High-Dose Methacholine Bronchoprovocation: The Modulating Effects of Deep Inspirations
… expiratory flow-volume curves (PEFV/MEFV) and impulse oscillometry (IOS) or (ii) traditional high-dose MCh challenge using MEFV, at each dose to a maximum change (∆) in FEV1 of 50% from baseline (MAX). Previously published data (Wasilewski et al., 2016) was used to compare the responses of …

Computational and experimental time domain, one dimensional models of air wave propagation in human airways
… with typical pressure and flow waveforms from impulse oscillometry system, which has recently been introduced as a clinical diagnostic technique, is also shown. The results suggested that a deeper investigation of the mechanisms underlying air wave propagation in lungs could be a useful tool to …

Lungenfunktionsdiagnostik bei jungen Kindern : Vergleich von Impulsoszillometrie und Spirometrie
… maneuvers can support cooperation in infants. Impulse oscillometry (IOS) is a new method for testing pulmonary function. Impulse-type measurement signals overlay the respiratory flow and are reflected in airways and in the lung. The reflection pattern is used for analysis of pulmonary …

Development of machine learning algorithms for screening of pulmonary disease
… The PFT laboratory tools included spirometry, impulse oscillometry, body plethysmography, and lung gas diffusion (DLCO). We first explored a multi-layer classification structure. Using this structure, the PFT machines produced good results on each classification layer: Healthy vs. Unhealthy …

Exactitud diagnóstica de la osilometría de impulso para el diagnóstico de asma en preescolares en una institución de Bogotá
El diagnostico de asma en preescolares es complejo, se ha implementado recientemente el uso de la oscilometría de impulso (IOS) pero aun no se conoce su exactitud diagnostica. Objetivo. Estimar la exactitud diagnóstica de la IOS comparándola con los patrones de referencia mas aceptados para asma en …

Diagnostische Relevanz der Impuls-Oszillometrie im Vergleich zur Bodyplethysmographie im Kindesalter
Die Impuls-Oszillometrie (IOS), die Ganzkörperplethysmographie (BP) und teilweise die Spirometrie wurden in der vorliegenden Arbeit umfassend beurteilt. Die Reliabilität der drei Methoden wurde durch Wiederholungsmessungen an zwölf gesunden Probanden überprüft. Ergebnisse der IOS wurden mit der BP …
