Abstract

A clean air environment in the operating area is an important factor in reducing intraoperative infection, which is affected by medical staff and their dynamic behaviour. In this study, experimental and numerical simulation methods were used to investigate the cleaning performance of the operation area under actual working conditions, which can more intuitively simulate the movement of particles in the operating room. First, four air distribution cases are studied: empty state, static persons, arm waving, and medical staff walking. Second, the disturbance process, distribution, peak value, and uniformity of particulate matter concentration in these cases are discussed. The results show that the air distribution in the operation area is greatly affected by the dynamic disturbance, the cleanliness level deteriorates by 2–3 levels, and the cleanliness uniformity also deteriorates further. Therefore, it is important to reasonably evaluate the mobile operation shelter cleaning performance and infection risk under actual working conditions.
