This study compared the intra-person consistency in measurements of respirator effect when determined in a laboratory and when determined in a field course setting. Results demonstrated that for physiologic parameters (including respiratory timing and ventilatory volumes) as well as subjective responses, field course measurements were at least as consistent as laboratory measurements. Because field measurements are inherently more likely to be work-related than routine clinical testing, their use may become increasingly important due to changes in the standard of practice and legal requirements, such as the Americans with Disability Act. A simple standardized field course may be developed without extensive equipment, and workers may be tested using their routine respirators on this course as a screening procedure to select the small number of workers who require extensive medical evaluation.
