LIFE SCIENCES HIGH-TECH OPERATING ROOM LT V - fi e l d FIGURE 6: Temperature distribution in the area of the operating table (LTV = low-turbulence velocity) FIGURE 9: CFD simulation of a hybrid OR with temperaturecontrolled directional airfl ow FIGURE 7: Comparison of simulated and measured temperature distributions FIGURE 8: Comparison between simulated fl ow visualization (left) and smoke visualization test (right) temperature distribution were also found to be in good agreement with the experimental data. A deviation of less than 2 % was achieved (see Figures 6 and 7). The effect of the OR fixtures on the airflow was also assessed. Figure 8 shows the flow field in the vicinity of the operating table, where a recirculation zone was predicted. A smoke visualization test was also performed and confirmed this finding. Through simulations, the observation was made that most medical devices (X-ray C-Bow, OR lighting, etc.), being located directly under the LAF ceiling, interrupt the protective TLAF fl ow, thereby posing an additional contamination risk. Additional turbulence zones introduced by airfl ow recirculation around the dummies ultimately cause impure air to fl ow from the outer area to the protected area, which increases the risk of microbiological contamination (see Figure 9). CONCLUSION Using CFD simulation, reliable predictions, both general and specific, about the airflow behavior and temperature distribution in the OR can be made. Furthermore, ventilation parameters can be optimized and general improvements suggested. The CFD results presented here clearly show that the Opragon ventilation system is a step in the right direction. Nevertheless, they also indicate that ventilation technology in the OR can only function effectively if it is successfully combined with optimized medical devices/fixtures and optimal work procedures.
