Impulse oscillometry (IOS) is a computer supported method for the measurement of complex mechanical airway characteristics. Bronchial obstructions can reliably be diagnosed by IOS when more complex parameters such as frequency dependence of resistance (FDR) and lung reactance (X5) are evaluated in cases with more severe obstruction. Parameters of conventional methods like pneumotachography, spirometry, and bodyplethysmography show relatively low correlations due to the different measurement… 
Impulse оscillometry in the diagnosis of moderate airway obstruction
TLDR
Impulse oscillometry can be used in the clinical practice to diagnose disorders of respiratory mechanics in patients with moderately severe airway obstruction and there were significant correlations between airway resistance and IOS parameters.

TLDR
Data show that techniques such as impulse oscillometry, nitrogen washout testing and analysis of exhaled nitric oxide are promising tools to assess involvement of the small airways.
Impulse oscillometry in the diagnosis of respiratory mechanics defects in chronic obstructive pulmonary disease
TLDR
IO can be used as an alternative method for assessing respiratory mechanics in COPD and progressively increased from stage I to stage IV (GOLD) of airway obstruction, while statistically significant changes of R rs20 were not detected.
IMPULSE OSCILLOMETRY FOR DIAGNOSIS OF EARLY CHANGES IN THE RESPIRATORY SYSTEM FUNCTIONAL STATE IN PATIENTS WITH MILD ASTHMA
TLDR
The absolute frequency dependence of Rrs5-Rrs20 and AX are the most informative parameters of impulse oscillometry, which are more significant in comparison with spirometry findings.
Reference Values of Impulse Oscillometric Lung Function Indices in Adults of Advanced Age
TLDR
Up-to-date reference equations for IOS in Caucasians aged 45 to 85 years are provided and the use of the present equations particularly in advanced age in order to detect airway dysfunction is suggested.
An informative value of impulse oscillonetry for detecting restrictive abnormalities in idiopathic pulmonary fibrosis
TLDR
IO was the most informative method for diagnosis of restrictive abnormalities in IPF patients: abnormal values, predominantly deltaXrs5, were found in 68% of the patients, and IO was less useful in patients with non-fibrotic respiratory diseases where abnormal basic IO values were less useful.
Impulse Oscillometry (IOS)
An impulse generator is used to apply small measurement oscillation pressure impulses to the respiratory system of a patient breathing normally. These impulses are multifrequency oscillations in
A role of impulse oscillometry for diagnosis of mild bronchial obstruction
TLDR
An abnormal increase in frequency-dependent resistive component of respiratory impedance (Rrs) at the oscillation frequency of 5Hrz and 10 Hrz was found in patients with mild bronchial obstruction and AX is more useful parameter as it increased in 64% of the patients.
[Technological Innovations in Pulmonology - Examples from Diagnostics and Therapy].
TLDR
The translation of basic findings about the lung microbiome into patient care may perspectively help to better understand and treat COPD exacerbations and the use of artificial intelligence in screening and early detection of diseases.
Application of impulse oscillometry and bronchial dilation test for analysis in patients with asthma and chronic obstructive pulmonary disease.
TLDR
The findings show, that X5, X25 and Fres may be useful for predictions and evaluations for COPD and R5, Zrs and Zrs may provide useful IOS parameters for asthma.
