残气量(RV)测定是临床诊断肺气肿的一个重要肺功能指标。但是,尸检资料表明生前残气量及残气占肺总量(TLC)百分比的改变与死后肺气肿病理形态学方面的发现并不密切吻合,而且,近来有人认为残气量增加不是肺气肿的特异性表现,慢性支气管炎也可见RV增加,因此如何评定残气量测定在肺气肿诊断中的意义,目前尚有争议。我院肺科1964年曾对159例慢性阻塞性肺气肿进行了临床观察,提出了以
Residual volume (RV) measurement is clinically diagnosed with emphysema is an important indicator of lung function. However, autopsy data suggest that changes in pre-ankle and residual percentage of total lung (TLC) are not closely related to the findings in post-mortem emphysema histopathology, and recently it has been suggested that increased residual volume is not emphysema Of the specific performance, chronic bronchitis can also be seen increased RV, so how to assess the significance of residual gas measurement in the diagnosis of emphysema, is still controversial. A total of 159 cases of chronic obstructive pulmonary emphysema were observed in our hospital in 1964,
