[Analysis of lung function in children with respiratory diseases and its clinical application].
To evaluate the clinical application of lung function analysis in diagnosis of children respiratory diseases.



Respiratory function was evaluated with portable lung function detector in 6 261 children with respiratory diseases. FEV1, FVC and PEFR were measured in 268 children with cough variant asthma (CVA) and 147 children with asthma (AS), and the results were self-compared during follow-up.



There were no significant differences in above parameters between children with cough variant asthma and those with asthma (P>0.05). Lung functions of asthma children were improved evidently by administration of glycocorticoid inhalator (P<0.001).



Lung function detection is essential for diagnosis of asthma and it can be used as a reliable index for therapeutic effect of asthma children.
