An evaluation has been undertaken of the efficiency of laminar-flow ventilation in operating-rooms in which conventional operating-room clothing was used. It has been demonstrated that velocities in the region of 0.3-0.4 m./sec. will give maximum returns for effort in both down-flow and cross-flow systems. At this velocity the laminar-flow system, in terms of airborne bacteria measured at the wound site, was about 11 times more efficient using horizontal air-flow and 35-90 times more efficient using vertical air-flow than a plenum-ventilated operating-room.
已对使用传统手术室服装的手术室中层流通风的效率进行了评估。结果表明，在0.3 - 0.4米/秒的速度范围内，下流式和横流式系统均能实现最大的效益回报。在此速度下，就伤口部位测得的空气传播细菌而言，层流系统采用水平气流时比全室通风手术室效率高约11倍，采用垂直气流时效率高35 - 90倍。
