EXPERIMENTAL STUDY OF AIR DISTRIBUTION WITHIN OPERATION ROOM

Abstract

The experimental analysis includes a patient lying on an operation table, surgical staff members, and surgical lights above the patient. The cold clean air is supplied to the room through grilles from ceiling diffusers and exhausted through low side walls. The first aim of the experimental study is to investigate the validity of air distribution within operation room and the effect of using the air filtering on the air flow distribution. Different air distribution system to what exists in the optical operation room, is also investigated by locating the inlet at the upper part of a side wall, while the exhaust grilles were in the lower part of the opposite side. From this study, it was found that the temperature and relative humidity in the surgical zone are 21.3oC and 49.3% in the optical operation room. While, the values in the experimental operation room are 23.6oC and 45.3%. These values in both operation rooms are in the acceptable range of the surgical conditions as well as for the carbon dioxide. Therefore, it can be using the wall air supply system in the operation room with good conditions for the surgical work.
