    Abstract: This article reviews the control of the key components of the surgical regional environment -importance and safety of Operating room Ceiling air supply unit. They believe that performance and its control of the surgical operating room air ceiling effects is more important than clean air zone control system from the surgical characteristics and requirements for environmental control. China's R & D products Ceiling air leakage resistance layer break the traditional theory and product models. the overall performance of the ceiling air supply has been greatly improved. Achieved the goals that surgical region's economic, effective control and the risk of surgical site infections greatly reduced. ......
