This investigation was the initial step in determining a clinical pulmonary test which could be used to evaluate workers as to their suitability to industrial respirator wear. Sixty subjects, 12 superior, 37 normal, and 11 moderately impaired with respect to lung function tests were evaluated with a battery of clinical pulmonary tests while wearing an industrial respirator. The respirator was a full-face mask (MSA-Ultravue) "demand" breathing type equipped with an inspiratory resistance of 85 mm H2O at 85 L/min air flow and an expiratory resistance of 25 mmH2O at 85 L/min air flow. Comparisons of these tests were made between the three groups of subjects both with and without a respirator. It appears that those lung tests which measure the flow characteristics of the lung especially those that are effort dependent are more susceptible to change as a result of respirator wear. Hence, the respirator affects the person with superior lung function to a greater degree than the moderately impaired person. It was suggested that the clinical test of 15 second maximum voluntary ventilations (MVV.25) may be the test of choice for determining worker capability in wearing an industrial respirator.
本研究是确定一项临床肺部测试的第一步，该测试可用于评估工人佩戴工业呼吸器的适宜性。60名受试者，根据肺功能测试，其中12名肺功能良好，37名正常，11名中度受损，在佩戴工业呼吸器时接受了一系列临床肺部测试。该呼吸器为全面罩（MSA-Ultravue）“按需”呼吸型，在85升/分钟气流下吸气阻力为85毫米水柱，呼气阻力为25毫米水柱。在有呼吸器和无呼吸器的情况下，对三组受试者的这些测试进行了比较。似乎那些测量肺部气流特性的肺部测试，尤其是那些依赖用力的测试，更容易因佩戴呼吸器而发生变化。因此，呼吸器对肺功能良好者的影响程度大于中度受损者。有人建议，15秒最大自主通气量（MVV.25）的临床测试可能是确定工人佩戴工业呼吸器能力的首选测试。
