Abstract
Objective To investigate the characteristics of respiratory impedance in children and adults with asthma and explore the clinical significance.Methods From Jul.2005 to Jun.2006 in Tianjin Children's Hospital, IOS (Impulse Oscillometry) was performed in 80 children and 62 adults with asthma and 112 healthy children to obtain respiratory impedance data; at the same time, the conventional pulmonary function test was also performed in some of the patients.Data coming from different groups were analyzed statistically.Results Based on IOS data, total resistance R5 increased ( 142.19 ± 36.40)% and central resistance R20 was normal[(88.53 ± 17.83)%]in child asthma group.Both R5 and R20 increased in adult asthma group[(190.03 ± 49.97)%, (152.53 ± 39.11)%].In two groups, reactance X5 and Fres decreased or backed off in various degrees, more obviously for Fres.The conventional pulmonary test data also implied that the percentages of FVC and FEV1/FVC were (81.19 ± 15.42)% and (55.57 ± 12.93)% respectively in adult group,and (79.12 ± 18.65)% and (64.81 ± 9.78)% respectively in child group.Conclusion The characteristics of respiratory impedance between children and adults are different.The pathological changes of child asthma are mainly in the small airway where inhaled medicine should reach as far as possible.关键词
