Measurements of ventilation and of inspired gas composition were made while volunteers breathed a non-anaesthetic gas through a Bain anaesthetic system. It was found that rebreathing occurred when the fresh gas flow was between two-and-a-half and three times the minute volume. Fresh gas flows at least three times the minute volume appear to be necessary to prevent rebreathing when using this system.
当志愿者通过贝恩麻醉系统呼吸非麻醉气体时,对通气和吸入气体成分进行了测量。结果发现,当新鲜气体流量在分钟通气量的2.5倍至3倍之间时,会发生重复呼吸。使用该系统时,新鲜气体流量至少为分钟通气量的3倍似乎是防止重复呼吸所必需的。
