ABSTRACT This study presents some field measurements in an operating room of air velocity, ambient temperature and particle counts on the operating table. Moreover, computational fluid Dynamics analyses of the operating room were performed and compared with the measurements. Measurements were taken under the preferred operating conditions by surgical staff (at 19 °C) and then at different ambient temperatures (from 20 to 22 °C,varying by one-degree increments) and average inlet air velocities (Vi) (0.1 and 0.2 m/s). The preferred one by surgical staff is 0.1 m/s and the maximum that can be reached is 0.2 m/s, with the current system. The results show that the particle count decreased at Vi of 0.2 m/s and low temperatures.

研究不同环境温度和入口速度下手术室中的颗粒数量

摘要 本研究展示了在手术室中对空气速度、环境温度和手术台上的粒子数进行的一些现场测量。此外，还对手术室进行了计算流体动力学分析，并与测量结果进行了比较。由外科工作人员在首选操作条件下（19 °C）进行测量，然后在不同的环境温度（从 20 到 22 °C，以 1 度为增量变化）和平均入口空气速度 (Vi)（0.1 和 0.2）下进行测量小姐）。外科工作人员的首选是 0.1 m/s，使用当前系统可以达到的最大值是 0.2 m/s。结果表明，粒子数在 0.2 m/s 的 Vi 和低温下减少。
