Recently,“Technical standards for respiratory oscillometry” was published, which reviewed
the physiological basis of oscillometric measures and detailed the technical factors related …

This review article is a summary of a seminar organised by the European Respiratory
Society on “The role of small airways in obstructive airway diseases” which was held in …

Rationale: Early detection of chronic obstructive pulmonary disease (COPD) exacerbations
using telemonitoring of physiological variables might reduce the frequency of …

The mechanical impedance of the respiratory system defines the pressure profile required to
drive a unit of oscillatory flow into the lungs. Impedance is a function of oscillation frequency …

RATIONALE: Current assessment of COPD relies extensively on the use of spirometry, an
effort-dependent maneuver. Impulse oscillometry (IOS) is a non-volitional way to measure …

The forced oscillation technique (FOT) is a noninvasive method with which to measure
respiratory system resistance and reactance during tidal breathing. Recently, its clinical …

Since its introduction in the 1950s, the forced oscillation technique (FOT) and the
measurement of respiratory impedance have evolved into powerful tools for the assessment …

Background The usual analysis of forced oscillometry measures respiratory resistance (Rrs)
and reactance (Xrs) averaged over several tidal breaths (whole-breath analysis). Recent …

Chronic pulmonary diseases such as asthma, COPD, and Idiopathic pulmonary fibrosis are
significant causes of mortality and morbidity worldwide. Currently, there is no radical …

Expiratory flow limitation (EFL) is present when the flow cannot rise despite an increase in
the expiratory driving pressure. The mechanisms of EFL are debated but are believed to be …
