摘要
对100例正常人F－V曲线吸气部分（MIFV）各指标进行分析，并对轻、中、重度慢性阻塞性肺病（COPD）患者MIFV各指标进行分析，以了解不同程度的COPD患者MIFV各项指标变化情况。经方差分析发现，除用力吸气肺量平均吸入时间（MTTin）外，其余各指标均有显著性差异，且用力吸气肺活量（FIV）、吸气肺活量（VCin）、吸气流速峰值（PIF）、75％肺活量最大吸气流量（VI_(75)）、VI_(50)、VI_(25)、0．5秒用力吸气容量（FIV_(0.5)）、FIV_(1.0)、吸至25％VC时的时间（TFIF_(50)）、TFIF_(50)、用力吸气肺量部分平均吸入时间（MTTpin）之间有高度显著性差异（P＜0．01）。作者认为：不同性别F－V曲线吸气部分各项指标数值有不同，其变化对判断COPD的病情严重程度有意义。
In this paper,we analyzed the indices of inspiratoryflow volume (MIFV) in 100 normal individuals andpatients with mild, moderate, severe chronic obstructivepulmonary disease(COPD) in order to understandtheir changes patients with different severity of COPD.Except MTTin, the other indices (FIV, VCin, PIF,VI_(75), VI_(25), FIV_(0.5), FIV_(1.0), FIFT_(75), FIFT_(50), MTTpin )were found to have remarkable differences between thetwo groups by x^2 test (P<0. 01 ). It is considered thatthere are some differences in the indices of inspiratoryflow volume of F - V curve between the male and thefemale and the changes of these indices have a significancein the assessment of the severity of disease ofCOPD.
