To determine whether the flight attendants who were exposed to secondhand tobacco smoke in the aircraft cabin have abnormal pulmonary function.
We administered questionnaires and performed pulmonary function testing in 61 never-smoking female flight attendants who worked in active air crews before the smoking ban on commercial aircraft (preban).
Although the preban flight attendants had normal FVC, FEV1, and FEV1/FVC ratio, they had significantly decreased flow at mid- and low-lung volumes, curvilinear flow-volume curves, and evidence of air trapping. Furthermore, the flight attendants had significantly decreased diffusing capacity (77.5% +/- 11.2% predicted normal) with 51% having a diffusing capacity below their 95% normal prediction limit.
This cohort of healthy never-smoking flight attendants who were exposed to secondhand tobacco smoke in the aircraft cabin showed pulmonary function abnormalities suggestive of airway obstruction and impaired diffusion.
确定在飞机客舱中接触二手烟草烟雾的空乘人员肺功能是否异常。
我们对61名在商业飞机禁烟前（禁令实施前）在现役机组工作的从不吸烟的女性空乘人员进行了问卷调查并进行了肺功能测试。
尽管禁令实施前的空乘人员用力肺活量（FVC）、第一秒用力呼气容积（FEV1）和FEV1/FVC比值正常，但她们在肺中、低容积时的气流显著降低，流量-容积曲线呈曲线状，并有空气潴留的证据。此外，空乘人员的弥散能力显著降低（预计正常的77.5%±11.2%），51%的人的弥散能力低于其正常预测极限的95%。
这组在飞机客舱中接触二手烟草烟雾的健康的从不吸烟的空乘人员表现出提示气道阻塞和弥散受损的肺功能异常。
