“…In restrictive lung diseases, there is typically no effect on the Resistance but a significant increase in A X . [30][31][32] Hence, oscillometry could help discriminate between various types of lung disease and add to the quality of diagnosis.…”

“…Both obstructive and fibrotic lung disease downwardly depress the reactance curve signaling an increase in respiratory system elastance. [30][31][32]53 While a stiffening of the respiratory system by fibrotic lung disease is easy to comprehend, it is less intuitive why this is so with obstructive lung disease. However, this is what sets oscillometry apart from other forms of lung function measurement.…”

Oscillometry is gaining in clinical use and while there is an increased interest in the technique, there is paucity in the understanding of its possibilities and limitations. Oscillometry has seen extensive use in research over several decades, but only recently is the technique being adopted in clinical practice; hence, there is a need to educate the novel users. The goal of the mini symposium arranged in San Diego in 2018 was to discuss the principles of oscillometry, showcase some of the recent ongoing research using this technique and to demonstrate how oscillometry may be used in clinical practice. It was concluded that oscillometry has several advantages over spirometry, most notably, with novel data being shown, its sensitivity allowing early detection of small airways disease not possible with spirometry and it can be used in subjects who have difficulties performing forced maneuvers such as preschool children, the elderly and subjects with handicaps. The site of respiratory pathology can be reflected by the various parameters generated by oscillometry and thus help with both disease diagnosis and localization. While the interpretation of oscillometry parameters and translating them into meaningful pathological correlates is still evolving, it is likely that oscillometry will soon be at the forefront of both pulmonary clinical practice and research. R ESUM EL'oscillom etrie est de plus en plus utilis ee en contexte clinique, mais malgr e l'int erêt accru pour cette technique, la compr ehension de ses possibilit es et de ses limites est encore insuffisante. Pendant plusieurs d ecennies, l'oscillom etrie a largement et e utilis ee dans la recherche, mais l'adoption de cette technique dans la pratique clinique est encore r ecente, de sorte qu'il est n ecessaire de former les nouveaux utilisateurs.

Il a et e d etermin e que l'oscillom etrie pr esentait plusieurs avantages par rapport a la spirom etrie notamment, comme le d emontrent de nouvelles donn ees, sa sensibilit e qui permet la d etection pr ecoce de la maladie des petites voies a eriennes, ce que la spirom etrie ne peut pas faire, ainsi que le fait qu'elle puisseêtre utilis ee aupr es de sujets qui eprouvent de la difficult e a effectuer des manoeuvres forc ees comme les enfants d'âge pr escolaire, les personnesâg ees et les personnes atteintes d'un handicap. L'emplacement de la pathologie respiratoire peut se refl eter dans les divers param etres produits par la spirom etrie, ce qui peut contribuer a diagnostiquer la maladie et a la localiser. Bien que l'interpr etation des param etres de l'oscillom etrie et leur traduction dans des corr elats pathologiques significatifs continue d' evoluer, l'oscillom etrie sera vraisemblablement a l'avant-plan de la pratique clinique et de la recherche pulmonair...
