Sensitivity study of pulsed pulmonary function and conventional pulmonary ventilation function in airway monitoring of children with asthma

Objective To explore the sensitivity of pulsed pulmonary function and conventional pulmonary ventilation in children with asthma airway monitoring. Methods The clinical data of 156 children with asthma who were admitted to the Third Department of Respiratory Medicine of Hebei Children′s Hospital from August 2017 to July 2018 were retrospectively analyzed.According to the clinical stage, 78 cases were divided into acute attack group and clinical remission group.Another 78 healthy children were taken as a healthy group, and the results of three groups of routine pulmonary ventilation function and pulsed concussion lung function were compared. Results The clinical remission group was superior to the acute exacerbation group in the pulsed pulmonary function and the conventional pulmonary ventilation function.The lung function indexes of the healthy group and the clinical remission group were similar.The R5, Zrs and Fres indicators in the healthy group were better than the clinical remission group.The difference was statistically significant (F=9.267, 6.025, 6.415, all P<0.05). Conclusions Both pulsed pulmonary function and conventional pulmonary ventilation are important measures for detecting lung function in children with asthma, but pulsed pulmonary function tests can further sensitively reflect changes in peripheral airway function, and early assessment of small airway function resistance in children during clinical remission.Change has important value.
