目的：呼吸器是用来维持工作表现和防止吸入毒素。本研究比较了两种常用的呼吸器类型--双筒式半面罩（HFM）和过滤式面罩（N95）对工作效率的影响。任务包括几个身体位置，努力水平，和浓度要求。为每项任务制定了准确性和速度的客观措施。每个任务的得分是基于受试者在所有科目中的排名。结果：所有科目都能够执行任务。呼吸器类型之间没有统计学上的显着差异，无论是任务performance metric.Conclusions：生产力的影响，可以有效地衡量，应被视为呼吸器设计测试的一部分，当选择最佳的呼吸器工人。
Objective:Respirators are used to maintain work performance and protect against inhaled toxins. The study compared the effects of two commonly used respirator classes—dual cartridge half face mask (HFM) and filtering face piece (N95)—upon work productivity.Methods:107 volunteers performed eight simulated work tasks when using the HFM and N95 respirators. Tasks included several body positions, exertion levels, and concentration requirements. Objective measures of accuracy and speed were developed for each task. Scores for each task were based on the subject's rank among all subjects.Results:All subjects were capable of performing the tasks. There were no statistically significant differences between respirator types in either task performance metric.Conclusions:Productivity impact can be measured effectively and should be considered as part of respirator design testing and when selecting the optimal respirator for a worker.
