作者应用苏联呼吸速度自动描记仪KT-8,对苏联顿巴斯煤矿慢性粉尘性支气管炎Ⅰ、Ⅱ期70例和矽肺Ⅰ期69例支气管运动障碍综合征进行了研究。分别于应用支气管扩张药前和应用舒喘灵后测定肺《流量/容量》环(《flux/content》loop,),判断大、中、小支气管通气障碍程度。 矽肺和慢性粉尘性支气管炎最大吸气速度降低为6.4/c。最大呼气速度,降低为6.26/c。最大通气
The author used the Soviet breath velocity automatic recording instrument KT-8 to study the bronchial dyskinesia syndromes of 70 cases of chronic dust bronchitis Ⅰ and Ⅱ and 69 cases of stage Ⅰ silicosis of Donbass Coal Mine in the Soviet Union. The lung “flux / content” loop (“flux / content” loop, respectively) was measured before administration of bronchodilator and after administration of salbutamol to determine the severity of bronchial airway obstruction. Silicosis and chronic dust bronchitis maximum aspiration rate decreased to 6.4 / c. The maximum expiratory speed, reduced to 6.26 / c. Maximum ventilation
