脉冲振荡肺功能检测在哮喘儿童支气管舒张试验中的临床价值

摘要

目的：探讨脉冲振荡肺功能检测在哮喘儿童支气管舒张试验中的临床价值。方法选取80例哮喘患儿随机分为实验组和对照组，采用ISO检测法和常规检测法分别进行检测并比较结果。结果实验组患者阳性37例（92．50％），对照组18例（55．00％），2组患者肺功能各项临床指标检出率比较，差异均有统计学意义（ P＜0．05）。所有患儿在试验后1秒用力呼气容积（FEV1）、共振频率（Fres）、呼吸总阻抗（Zrs）、总气道黏性阻力（R5）、周边气道黏性阻力（R20）、周边弹性阻力（X5）各项临床指标均有明显的改善，差异均有统计学意义（ P＜0．05）。结论脉冲振荡肺功能检测可以准确判断支气管哮喘的各项临床指标的变化，具有临床应用价值。%Objective To explore the application value of pulse oscillation pulmonary function test in bronchial asthma children diastolicMethods 80 cases of children with asthma who were adopt ISO tests and conventional tests for testing ,statistics ,statistical analysisd .Results 37 (92 .50% ) cases patients in the experimental group were posi‐tive ,while 18 cases (55 .00% ) patients in the control group were positive .The clinical indexes of Lung function in two groups of patients was significant difference .After the experimental ,FEV1 ,Fres Zrs ,R5 ,R20 ,X5 were obvious improved (P<0 .05) .Conclusion Pulse oscillation lung function measurements can accurately determine the change of clinical indicators of bronchial asthma in children ,and can provide a reliable basis for the treatment of patients .
