Abstract： 目的研究婴幼儿肺炎时小气道阻塞程度及肺功能损害程度. 方法运用潮气呼吸流速容量环(TBFV环)对82例婴幼儿肺炎进行治疗前后肺功能各项指标比较. 结果发现治疗后TBFV环形态有很大的变化,反映小气道功能中到达潮气呼气峰流速时的呼气量/潮气量(%V-PF)及呼出75%潮气量时的呼气流速/潮气呼气峰流速(25/PF),潮气呼气峰流速(PTEF)差异均有显著意义(p<0.05).反映通气功能的每公斤潮气量(TV/kg)、呼吸频率(RR)差异有显著意义(p<0.05).反映大气道阻塞位置与损害程度的潮气呼气中期流速与潮气吸气中期流速之比(ME/MI)治疗前后差异无显著意义(p>0.05). 结论提示TBFV环可作为评价临床上婴幼儿肺炎的轻重程度,肺功能的损害程度以及观察治疗效果客观的重要依据,值得临床推广应用.
