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 …

Precision Background Stability and Response Calibration in Borexino: Prospects for Wideband, Precision Solar Neutrino Spectroscopy and BSM Neutrino Oscillometry Through a Deeper Detector Understanding
This work sets out to be a description of the initiatives utilizing the Borexino liquid scintillator neutrino observatory to perform the first direct, high-precision, wideband solar neutrino spectroscopy measurement of the the solar neutrino spectrum's main components, as well as its …

EXPLORING EQUINE ASTHMA: PATHOGENESIS INSIGHTS AND DIAGNOSTIC CHALLENGES
… capacity in cases of neutrophilic inflammation. Oscillometry studies proved to be encouraging, revealing differences in respiratory reactance between healthy and MEA-affected horses in a mixed population. Conversely, among racehorses in training, no differences in lung function were observed at …

A wearable blood pressure sensor using oscillometric photoplethysmography and micro accelerometers
… arm. In this work, the principle of hydrostatic oscillometry is first detailed. To better understand the internal mechanisms of pressure propagation within the tissue, a comprehensive non-linear finite element model of the finger base is constructed and validated using a combination of magnetic …

From sneeze to wheeze: Non-invasive studies on asthma and rhinitis
… 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, with …

Impact of Prolonged Sitting on Central Hemodynamics: Role of Intermittent Pneumatic Compression Therapy
… using carotid applanation tonometry coupled with oscillometry performed on left upper-thigh. For mechanistic insight, intermittent pneumatic compression (IPC) was applied during sitting (i.e., 3, 120 mmHg compression cycles per minute, 30 mins on/off) in a sub-set (N=9). <strong>Results:</strong> …

Central blood pressure
… Peripheral blood pressure was measured by oscillometry and peripheral blood pressure waveforms were obtained from blood pressure cuffs, radial tonometry and a servo-controlled finger cuff. To address objective 4 additional measurements of ventricular and arterial mechanics where made using …

Lung function in smokers - Aspects on COPD diagnosis and associations to atherosclerosis and alcohol consumption
… 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 association …

Assessing Endothelial Dysfunction Estimating the Differences Between 3 Minute and 5 Minute Reactive Hyperemia
… to assess endothelial dysfunction using oscillometry techniques. Endothelial dysfunction is the most significant predictor of a major adverse cardiovascular event, so this test can be used as an early detection tool for cardiovascular disease and allow patients to find treatment before …

Sensory-Mechanical Responses to High-Dose Methacholine Bronchoprovocation: The Modulating Effects of Deep Inspirations
… 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 healthy …

Computational and experimental time domain, one dimensional models of air wave propagation in human airways
… 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 better …

Development of machine learning algorithms for screening of pulmonary disease
… 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 [AUC=0.90 …

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 …
