本文旨在观察老年残气量增高对通气与弥散功能的影响,从而探讨生理性与病理性肺气肿的鉴别。151例男性老年人的检查资料表明,无心肺疾患之健康组,RV/TLC、DLco,FEV1.0％、50、25等参数均明显优于吸烟组、冠心病组、陈旧性肺结核组及慢性支气管炎组(P<0.05～0.01)。随残气量的增高,DLco、V50、V25均有极显著下降(P<0.01),FEV1.0％也有相应的下降,但无统计学差异,而FEV1.0％在慢性阻塞性肺气肿下降极明显。故认为以RV/TLC、V50、25、及FEV1.0％四项综合考虑,以判断老年患者肺气肿为生理性抑为/并病理性,有一定实用价值。
The purpose of this paper is to observe the effect of elderly residual volume on ventilation and diffusive function, so as to explore the differential between physiological and pathological emphysema. The data of 151 elderly male patients showed that the parameters of RV / TLC, DLco, FEV1.0%, 50,25 in the healthy group without heart and lung disease were significantly better than those in the smoking group, coronary heart disease group, old tuberculosis group and chronic Bronchitis group (P <0.05 ~ 0.01). The DLco, V50 and V25 decreased significantly (P <0.01) and the FEV1.0% decreased correspondingly with the increase of residual volume, but there was no statistical difference, while FEV1.0% decreased in chronic obstructive pulmonary emphysema Obvious. Therefore, taking RV / TLC, V50,25, and FEV1.0% into consideration, it is of practical value to judge that the elderly patients with emphysema are physiological and / or pathological.
