1.本文报告76例慢性支气管炎的肺功能测验,测验结果:随患病时间延长肺功能逐渐减退(个别病例例外),在损害的肺功能项目中,通气量最明显,肺容量次之,换气功能仅表现轻度氧吸收降低。 2.76例三年以上的慢性支气管炎中, 84.2％发展成肺气肿,肺功能测验对肺气肿的诊断,比临床诊断高22.36％。 3.最大呼气中期流速与最大通气量改变非常相近,由76例患者组实际测得值中计算出,最大呼气中期流速(升/秒)乘41.2±3.17等于最大通气量,此数值似可做为最大通气量的一种间接测定方法,但需继续观察和研究。
1. This article reports 76 cases of chronic bronchitis lung function tests, the test results: With the prolonged lung function gradually decline (with exceptions in some cases), in the damage of pulmonary function items, ventilation was the most obvious, followed by lung capacity, Ventilation showed only a slight decrease in oxygen absorption. Of the 2.76 cases of chronic bronchitis over three years, 84.2% developed emphysema, and the pulmonary function test was more diagnostic of emphysema than the clinical diagnosis of 22.36%. 3. The maximal mid-expiratory flow rate is very similar to the maximal ventilation change and is calculated from the actual measured values of 76 patient groups. The maximum mid-expiratory flow rate (L / s) times the maximum ventilation by 41.2 ± 3.17 equals the maximum ventilation Can be used as an indirect measurement of maximum ventilation, but need to continue to observe and study.
