消防队员在救火时吸人烟雾对肺功能的影响各家意见不一。既往报告中的肺功能皆限于总的通气功能,反映不出小气道的情况。本文报告了应用呼吸空气和氦(80%)氧(20%)混合气体所测得流速-容量曲线来观察消防队员救火时烟雾吸入对肺功能的急性和慢性影响。计54名消防队员,年龄24～59岁,平均37岁。22名不吸烟(Ⅰ组),33名吸烟(Ⅱ组)。平均工龄为12年(Ⅰ组为16年,Ⅱ组为10年)。每名消防队员皆测定第一秒时间肺活量(FEV_1)及肺活量(FVC)。Ⅰ组17名,Ⅱ组26名还作了流速-容量曲线,按呼
Smoke firefighters inhalation of smoke on the lung function of different opinions. Lung function in previous reports were limited to the general ventilation function, reflecting the small airway situation. This paper reports the flow-volume curve measured using a mixture of breathing air and helium (80%) oxygen (20%) to observe the acute and chronic effects of smoke inhalation on lung function during firefighting firefighters. 54 firefighters, aged 24 to 59 years, an average of 37 years old. Twenty-two non-smokers (group I) and 33 smokers (group II). The average length of service is 12 years (group I, 16 years, group II, 10 years). Each firefighter determined the vital capacity (FEV_1) and vital capacity (FVC) in the first second. Group I 17, Group II 26 also made a flow rate - capacity curve, according to call
