在慢性阻塞性肺疾患中,因鉴别气道可逆性阻塞的支管哮喘(咳喘)和不可逆性阻塞的肺气肿等在治疗及判断预后上极为重要,故作者选择哮喘和慢性肺气肿各11例在吸入2%间经异丙肾上腺素后测定肺气量及流速—容量(F—V)曲线、比较两组吸入支气管舒张剂的效果和F—V曲线的特证。结果:①哮喘组残气量和肺总量的百分比(T/VRLC%)23～43%(平均36±7%),△N_20.5～2.5%(平均1.3±0.7)肺气肿组RV/TLC%53～72%(平均64±7%),△N_24.6～10.1%(平均7.0±1.9%)两组
In chronic obstructive pulmonary disease, the author chooses asthma and chronic emphysema for the purpose of identifying and treating the bronchial asthma (asthma) that is reversibly blocked in the airways and the emphysema of irreversible obstruction in the treatment and prognosis. Eleven patients underwent inhalation of 2% inter-isoproterenol and then measured pulmonary volume and flow-volume (F-V) curves. The effects of inhaled bronchodilators and F-V curves were compared between the two groups. Results: ① The percentages of residual volume and total lung volume in asthma group were 23 ~ 43% (average 36 ± 7%) and △ N 20.5 ~ 2.5% (average 1.3 ± 0.7) in RV / TLC% 53-72% (average 64 ± 7%), ΔN_24.6-10.1% (average 7.0 ± 1.9%), two groups
