Measuring lung function in small children is extremely difficult and confined to highly specialized institutions. EVI showed to be a feasible unintrusive alternative, allowing also home measurements which had not been previously compared to some of the standard measures of LF. Our study showed, for the first time that, besides clinical association, EVI is also associated with oscillometric LF (post-bronchodilation X5). The association seen for reactance and not resistance is most probably associated with the presumably higher sensitivity of reactance for acute airway obstruction (doi: 10.1016/j.anai.2020.07.002). The results of our study provide further evidence for EVI as an objective measure of LF in preschool children with obstructive airway disorders.
