Research progress on operational characteristics influencing factors of operating room environment: A review

The unidirectional flow ventilation system in the operating room can protect the surgical area under at-rest condition. However, research results show that the operational and at-rest characteristics of the operating room are very different, and that the airflow pattern in the surgical area is close to a mixed status under operational condition. The study methods of operating room environment can be divided into statistical method, simulated operation method and numerical simulation method. Reviews the operational characteristics and the impact of personnel on the clean environment of the operating room. The occupants and their activities are important factors that affect the clean environment of the operating room, in which the human body is a complex dust source, and the impact of occupants’ activities in the operating room on the surrounding environment is complex and variable. It is important for the operation and management of the operating room to protect and monitor the clean environment under operational condition.
