Respiratory impedance (Zrs) 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 ER -
