Thirty-four production workers at three chemical plants were tested for acute changes in lung function over the course of their three-day, twelve-hour workshift. Mean percentages of the predicted lung function indices (FVC, FEV, and FEF 25-75) showed a workshift decrement, particularly evident in the evening shift. A workweek effect was shown in that no recovery in mean %FEV1 and %FEF-25-75 was shown by the last working day. Diurnal variation in respiratory function was regarded as being only partly responsible for the observed workshift effect.
对三家化工厂的34名生产工人在其为期三天、每班12小时的轮班期间进行了肺功能急性变化测试。预测肺功能指标(用力肺活量、一秒用力呼气容积和25%-75%用力呼气流量)的平均百分比显示在轮班期间有所下降,在晚班时尤为明显。显示出一周工作日的影响,即到最后一个工作日,一秒用力呼气容积平均百分比和25%-75%用力呼气流量平均百分比没有恢复。呼吸功能的昼夜变化被认为只是观察到的轮班效应的部分原因。
