Abstract

Forced oscillation technique (FOT) is a measure of respiratory impedance first described by DuBois more than 60 years ago [1]. Respiratory impedance ( Z rs ) can be calculated by superimposing sound waves on normal tidal breathing without special breathing manoeuvres. New estimated useful thresholds for the bronchodilator response in oscillometry parameters in healthy adults. These thresholds are lower than those proposed by recent guidelines. https://bit.ly/3xufqla
