A passive method for the disposal of waste anaesthetic gases is described. The resistance characteristics of the collector valve, the balancing device and the disposal system were studied. It was found that the resistances offered by the conduction channels and the terminal exhaust valve were extremely low. The collector valves were found to be responsible for most of the expiratory resistance. Swabs taken from various components of the system showed that these were contaminated mainly with commensals and non-pathogenic organisms.
描述了一种处理废麻醉气体的被动方法。研究了收集阀、平衡装置和处理系统的阻力特性。发现传导通道和终端排气阀的阻力极低。发现收集阀是呼气阻力的主要来源。从系统的各个部件上采集的拭子显示，这些部件主要被共生菌和非致病生物污染。
