Respirator Effects in Impaired Workers

摘要-项目总结 该研究项目将开发和评估方法， 许多人（激增应对措施）和小工作场所的工人无法获得 职业健康专家。这项工作将比较三种培训方法（印刷 小册子、视频和基于计算机的）。决定呼吸机耐受性的因素将是 研究了这些包括多领域的主观反应和生理因素 例如呼吸模式和呼吸调节工作。个人的影响 健康状况和心理物理呼吸负荷敏感性等因素将 研究了这项工作将包括促进掩模尺寸选择的方法（例如，面部 尺寸）和使用热成像来识别面部密封表面泄漏。 将对定量配合测试、模拟工作性能和公差进行评估 在训练后和六个月后。一组不同的主题将 招聘，将包括英语和西班牙语的发言者;弹性半面罩， 将使用过滤面罩呼吸器。跨部门研究将建立 根据最近的调查，并可能导致更有效的呼吸保护 程序.

ABSTRACT- PROJECT SUMMARY The research project will develop and evaluate methods for rapidly respirator-enabling many persons (surge response) and workers in small workplaces without access to occupational health experts. The work will compare three training methods (printed brochure, video, and computer-based). Factors determining respirator tolerance will be investigated. These include multi-domain subjective responses and physiologic factors such as respiratory pattern and work of breathing adjustment. The effect of personal factors such as health status and psychophysical respiratory load sensitivity will be investigated. The work will include methods to facilitate mask size selection (e.g., facial dimension) and the use of thermal imaging to identify facial sealing surface leakage. Quantitative fit testing, simulated work performance, and tolerance will be evaluated immediately after training and after six months. A diverse group of subjects will be recruited and will include English and Spanish speakers; elastomeric half facemask and filtering facepiece respirators will be used. The proposed cross sector research will build upon recent investigations and potentially lead to more effective respiratory protection programs.
