Vocal Cord Dysfunction as Demonstrated by Impulse Oscillometry [PDF]

The Journal of Allergy and Clinical Immunology: In Practice, 2013
Vocal cord dysfunction (VCD) is a respiratory disorder characterized by inappropriate vocal cord adduction during inspiration. The diagnosis of VCD is challenging, because expected flow volume loop abnormalities are uncommonly noted, and laryngoscopy must be timed to coincide with symptoms.We wanted to determine the potential role of impulse ...

Assessment of functional tests on determining resistance of respiratory tract in patients with bronchial asthma, COPD and their combination.

Medičnì Perspektivi, 2017
The mechanical properties of the respiratory tract (including airway resistance) is an important indicator of pulmonary function, and definition of resistance is used to diagnose and monitor obstructive lung diseases. This study was performed in order to

The case for impulse oscillometry in the management of asthma in children and adults [PDF]

, 2017
Objective: To provide a clinical rationale for including impulse oscillometry (IOS) as a part of standard office-based asthma assessment.Data Sources: PubMed and Google search, limited to English language and human disease, with the keywords IOS and ...

Impulse oscillometry for the evaluation and management of pediatric asthma [PDF]

Exploration of Asthma & Allergy, 2023
Asthma is the most common chronic disease during childhood. While most of characteristic structural changes in asthma have been identified in the large airways, there is a growing recognition of peripheral airway dysfunction as a crucial factor in the ...

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 bronchodilator response in preschool children: A systematic review [PDF]

, 2016
BACKGROUND: The bronchodilator response (BDR) is frequently used to support diagnostic and therapeutic decision-making for children who wheeze. However, there is little evidence-based guidance describing the role of BDR testing in preschool children and ...

Sensitivity of lung resistance and compliance to beta-blocker induced bronchoconstriction and long acting beta-agonist withdrawal in COPD [PDF]

, 2017
Little is known about impulse oscillometry (IOS) in COPD. IOS is an effort independent measure of lung resistance and reactance (compliance).

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.

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].
