An expired gas collection and disposal system based on an independent suction pump is described. The halothane concentration in the atmosphere was measured, with and without the system. The increase of halothane concentration was limited to 1 p.p.m. above the theatre basal value with the system in use, and 5 p.p.m. when no venting was used.
描述了一种基于独立抽吸泵的呼出气体收集和处理系统。在有和没有该系统的情况下,测量了大气中的氟烷浓度。使用该系统时,氟烷浓度的增加限制在高于手术室基础值1 ppm以内;不进行通风时,氟烷浓度增加5 ppm。
