Respirator Effects in Impaired Workers

描述（由申请人提供）：该研究项目将开发和评估快速呼吸器的方法，使许多人（激增反应）和小型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、录像和计算机培训）。将调查决定呼吸器耐受性的因素。这些包括多领域的主观反应和生理因素，如呼吸模式和呼吸调节工作。个人因素如健康状况和心理生理呼吸负荷敏感性的影响将被调查。这项工作将包括促进掩膜尺寸选择的方法（例如，面部尺寸）和使用热成像来识别面部密封面泄漏。定量配合测试、模拟工作表现和容忍度将在培训后和六个月后立即进行评估。将招募各种各样的对象，包括讲英语和西班牙语的人；使用弹性半口罩和过滤式口罩。拟议的跨部门研究将以最近的调查为基础，并可能导致更有效的呼吸保护计划。

DESCRIPTION (provided by applicant): 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. PUBLIC HEALTH RELEVANCE: The research project will develop and evaluate methods for enabling users to safely and effectively use respirators. The project will compare three training methods (printed brochure, video, and computer-based), assess subjective and physiologic factors determining respirator tolerance, and develop methods for mask size selection and thermal imaging for leak detection. The research will contribute to the ability to rapidly respirator-enable many persons (surge response) and workers and small workplaces.
