To minimize postoperative infections, ultraclean laminar airflow (LAF) units equipped with high-efficiency particulate air filters developed for electronic and aerospace technology have been adapted for ORs. Traditionally, the airflow was either vertical or horizontal and, to function properly, encompassed extra side walls inside the OR. Recently, new airstream technology has provided zoned down-flow units that provide an exponential airflow (i.e., resembling an upside-down trumpet mouth). The exponential airflow allows for omission of extra side walls, making them more versatile in clinical use. Each different type of LAF requires knowledge of airstream patterns and how OR team members need to dress and work to prevent contamination of the sterile air and the aseptic areas. This article discusses different LAF systems and related demands on OR clothing and behavior.
为尽量减少术后感染，配备了为电子和航空航天技术开发的高效空气微粒过滤器的超净层流空气（LAF）装置已被应用于手术室。传统上，气流为垂直或水平方向，且为正常运行，手术室内部设有额外的侧壁。最近，新的气流技术提供了分区向下气流装置，可提供指数气流（即类似倒置的喇叭口）。指数气流无需额外的侧壁，使其在临床应用中更具通用性。每种不同类型的层流空气装置都需要了解气流模式以及手术室团队成员应如何着装和操作，以防止无菌空气和无菌区域受到污染。本文讨论了不同的层流空气系统以及对手术室着装和行为的相关要求。
