Diagnostic value of impulse oscillometry in chronic obstructive pulmonary disease: a multicentre, retrospective, observational study. [PDF]

BMJ Open
Objectives Diagnosis and assessment of chronic obstructive pulmonary disease (COPD) rely extensively on spirometry, which necessitates patient cooperation.

Repeatability of impulse oscillometry in patients with severe asthma

European Respiratory Journal, 2021
Impulse oscillometry (IOS) involves an effort independent tidal breathing manoeuvre to determine the presence or absence of small airways dysfunction (SAD), defined as raised peripheral airway resistance (difference in resistance between 5 and 20 Hz (R5-R20)) and/or raised peripheral airway reactance (area under the reactance curve (AX)) [1].

IMPULSE OSCILLOMETRY FOR DIAGNOSIS OF EARLY CHANGES IN THE RESPIRATORY SYSTEM FUNCTIONAL STATE IN PATIENTS WITH MILD ASTHMA

Архивъ внутренней медицины, 2019
Currently, the analysis of respiratory function of lungs at suspicion of obstructive pulmonary diseases is recommended to start with spirometry as the most sensitive method of obstruction detection. However, data on informative value and specificity of a

Does size really matter:relationship of particle size to lung deposition and exhaled fraction [PDF]

, 2017
We demonstrate that extra-fine particles are not associated with an appreciably higher exhaled fraction, hence explaining their efficacy profile in asthma.

The role of impulse oscillometry in assessment of airway obstruction in smokers and ex-smokers

Egyptian Journal of Chest Disease and Tuberculosis, 2012
Background: Impulse oscillometry provides useful clinical information that prominently includes functional assessment of small, peripheral airway behavior beyond that available from commonly used pulmonary function tests (PFT).

Safety, tolerability, pharmacokinetics and pharmacodynamics of the spleen tyrosine kinase inhibitor BI 894416 in healthy volunteers and patients with asthma

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Spleen tyrosine kinase (SYK) has broad biological functions in inflammation and immunity. The orally administered SYK inhibitor BI 894416 was investigated in a single‐rising‐dose Phase I study in healthy volunteers and in a combined single‐ and multiple‐rising‐dose Phase Ib study in patients with mild asthma ...

Exploratory study into the effect of abdominal mass loading on airways resistance and ventilatory failure [PDF]

, 2016
Objective We hypothesised that the airway resistance during tidal breathing would correlate with a particular pattern of increasing obesity, particularly when supine, and would differ between participants with and without ventilatory failure.
