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

The small airways are defined as those less than 2 mm in diameter. They are a major site of
pathology in many lung diseases, not least chronic obstructive pulmonary disease (COPD) …

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 …

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 …

Owing to its major and better recognised burden from both individual and societal
perspectives, chronic obstructive pulmonary disease (COPD) is an area of intensive …

In recent years special interest has been expressed for the contribution of small airways in
the pathophysiology, clinical manifestations and treatment of asthma and COPD. Small …
