本文对70例哮喘患儿进行了 VC、FEV_(1.0)等8项肺功能指标的检查和分析,指出常规肺功能6项指标中,以 FEV_(1.0)和 MVV 最敏感,RVI、TVC 和FEV_(1.0)%次之,VC 的敏感性最差。小气道功能指标中,(?)_(25)/HT 和 PEFR 均非常敏感,在对哮喘患儿进行肺功能检查时,可酌情选择能反映大、小气道功能的 FEV_(1.0)、FEV_(1.0)%、MVV 及(?)_(25)/HT、PEFR 等5～6项指标,进行综合分析,这对早期发现轻症和非典型哮喘患者和指导治疗及防止“残余哮喘”的发生,都具有重要意义。
In this paper, 70 children with asthma were examined by VC and FEV_ (1.0) and other 8 indexes of lung function. Among the 6 indexes of routine lung function, FEV_ (1.0) and MVV were the most sensitive, RVI, TVC and FEV_ (1.0)%, VC is the least sensitive. Small airway function indicators, (?) _ (25) / HT and PEFR are very sensitive in the assessment of lung function in children with asthma, may choose to reflect the large and small airway function FEV 1.0, FEV_ 1.0%), MVV and (?) _ (25) / HT, PEFR and other indicators of 5 to 6, a comprehensive analysis of early detection of mild and atypical asthma in patients and to guide treatment and prevent the occurrence of “residual asthma” , Are of great significance.
