Flow-Volume Parameters in COPD Related to Extended Measurements of Lung Volume, Diffusion, and Resistance

Pulmonary Medicine, 2013
Classification of COPD into different GOLD stages is based on forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) but has shown to be of limited value.

Role of the impulse oscillometry in the evaluation of tracheal stenosis

Pulmonology, 2018
Tracheal stenosis is a rare and challenging disease. Bronchoscopy is the gold standard for diagnosis and assessment but brings inherent risks. Spirometry is commonly used to access obstructions but is not always feasible due to patient related factors.

Minimal Clinically Important Difference for Impulse Oscillometry in Adults with Asthma.

, 2023
BACKGROUND Impulse oscillometry (IOS) allows an effort-independent evaluation of small airway function in asthma. Unfortunately, well-determined minimal clinically important differences (MCID) for IOS-measures are lacking.

Impulse Oscillometry as a Predictor of Asthma Exacerbations in Young Children [PDF]

Respiration, 2016
<b><i>Background:</i></b> In a post-hoc analysis of a pediatric asthma study, we identified the predictors of asthma exacerbations (AEs) and related them to forced expiratory volume (FEV₁), the FEV₁/FVC ratio, and bronchial hyperresponsiveness (BHR). <b><i>Objectives:</

Nasal Airway Transcriptome Reflects Selected Asthma‐Associated Gene Signatures in the Lower Airways

Allergy, EarlyView.
Seven genes and two gene modules were consistently associated with asthma in both airway compartments in ARMS and were validated in ATLANTIS. The two modules reflected IL‐13 related inflammation and mast cell activity, respectively. Nasal gene signatures provide a non‐invasive proxy for selected bronchial asthma‐associated gene signatures.

Airwave oscillometry and patient reported outcomes in persistent asthma [PDF]

, 2020
Airwave oscillometry (AOS: Tremoflo, Thorasys, Montreal) is a modern forced oscillation technique (FOT) using a vibrating mesh to superimpose forced oscillations of sound waves on top of normal tidal breathing to measure respiratory impedance as lung ...
