The usefulness of oscillometry in adult clinical practice has not been clarified.

Compared at the same FEV<jats:sub>1<\/jats:sub>level, asthma, COPD, bronchiectasis, UAO and ILD displayed different oscillometric characteristics. The z-score of resistance at 5\u2005Hz (<jats:italic>R<\/jats:italic><jats:sub>5<\/jats:sub>) was the best variable to identify respiratory diseases with a sensitivity of 62.4\u201366.7% and a specificity of 81.5\u201390.3%.
