The application and clinical significance of impulse oscillometry lung function in children with bronchial asthma / 中国医师进修杂志

ABSTRACT

Objective To investigate the clinical application and diagnostic value of impulse oscillometry lung function in children with bronchial asthma.Methods Thirty-two children (19 children in acute attack group,13 children in clinical remission group) with bronchial asthma were selected,and 20 healthy children as control group.The lung function simation by Master Screen impulse oscillometry device was detected.Results The outcome of the R5,R20,R5-R20,the negative of X5 and Fres in acute attack group (21.90±2.70) Hz]were higher than those in clinical remission group [(7.75±0.97),(3.82±0.50),outcome of the R5,R5-R20 and Fres in clinical remission group were higher than those in control group (P＜0.05),but there were no statistical significance in R20 and X5 in the two groups (P＞0.05).Conclusion Impulse oscillometry can provide various objective indicators to bronchial asthma in acute attack and clinical remission stage.which can be used as a method in detecting pulmonary function and monitoring therapy of bronchial asthmatic children.
