Post-bronchodilator eversibility in asthmatic children with normal baseline spirometry
What is it about?
In this study we wished to evaluate the frequency of post-bronchodilator reversibility of spirometry in asthmatic children with baseline spirometry within the limits of normal
Why is it important?
We first found that around two third of asthmatic children referred to our tertiary hospital pulmonary function laboratory has a normal baseline spirometry. Among these children, only 5% had a post-bronchodilator significant reversibility. We established thresholds to distinguish children with or without reversibility with a sensitvity of 90 % (i.e. 0.42 Z-score for FEV1 and −0.16 Z-score for FEV1/FVC)
