Respirator Effects in Impaired Workers

描述（由申请人提供）：该研究项目将开发和评估方法，用于快速激活许多人（浪涌响应）和小型工作场所的工人，而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，视频和计算机）。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的工作。将研究个人因素（如健康状况和身心呼吸负荷敏感性）的影响。该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。在培训后和六个月后，将立即对定量适合性测试、模拟工作表现和公差进行评估。将招募一组不同的受试者，包括讲英语和西班牙语的受试者;将使用弹性半面罩和过滤面罩。拟议的跨部门研究将建立在最近的调查基础上，并可能导致更有效的呼吸保护计划。 公共卫生相关性：该研究项目将开发和评估使用户能够安全有效地使用呼吸机的方法。该项目将比较三种培训方法（印刷小册子、视频和计算机），评估决定呼吸机耐受性的主观和生理因素，并开发面罩尺寸选择和泄漏检测热成像方法。这项研究将有助于提高快速发电机的能力，使许多人（激增反应）和工人和小工作场所。

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.
