Monitoring of respiratory resistance in the diagnosis of mild‐intermittent asthma

Abstract

The evidence of significant variability in lung function is required to confirm the clinical diagnosis of asthma [1]. This is commonly obtained in laboratory settings by bronchoreversibility or bronchoprovocation testing. Because the hallmark of asthma is the variability of symptoms, a more clinically relevant method to confirm the diagnosis should be by revealing an increase of spontaneous variability in lung function [1].
