本文通过100例煤工尘肺胸部X线和RV(残气)测定的对比观察,发现煤工尘肺肺气肿的并发率分别为56.0％和75.0％,并证实肺气肿的并发率随煤工尘肺期别的增高而增加。胸部X线和RV测定两者诊断肺气肿的总符合率为66.6％。Ⅰ期煤工尘肺时,RV增高、RV/TLC％增加的例数显著高于胸部X线肺气肿所见的例数,说明在早期发现煤工尘肺并发肺气肿的诊断上RV测定的价值较大。
In this paper, 100 cases of coal workers pneumoconiosis chest X-ray and RV (residual gas) comparison of the observed and found that coal workers pneumoconiosis complicated by rates were 56.0% and 75.0%, and confirmed the concurrent rate of emphysema with coal workers Pneumoconiosis increased in other increases. The total coincidence rate of chest X-ray and RV in diagnosing emphysema was 66.6%. In the first stage of coal miners’ pneumoconiosis, RV increased and the RV / TLC% increase was significantly higher than that seen in chest X-ray emphysema, indicating that in the early diagnosis of coal worker’s pneumoconiosis complicated by emphysema Greater value.
