摘要

麻醉教科书详细描述了与可变旁路蒸发器中产生的分流比相关的计算。这些计算基于载气流量的假设(例如:假设为 150 毫升),就像使用定量流量蒸发器一样[1,2]。可变旁通蒸发器中的载气流量是针对特定剂型的、动态的、未知的,且与操作者无关,因此在与可变旁通蒸发器相关的计算中假设载气流量是不合理的[3]。尽管技术不断进步,但产生的蒸气量仍是根据临床上不切实际的假设来计算的。本文提出了一种简单的方法和公式,用于快速估算七氟醚可变旁路气化器的蒸汽输出量、载气流量并确定分流比。

Splitting ratio in sevoflurane vapouriser-a relook on calculations
Textbooks of anaesthesia describe in detail the calculations associated with splitting ratios created in variable bypass vapourisers. These calculations are based on assumptions of carrier gas flow (eg:assume 150 ml) as practised with measured flow vaporizers[1,2]. Carrier gas flow in a variable bypass vaporizer is agent specific,dynamic,unknown and operator independent.Therefore assuming carrier gas flow in calculations related to variable bypass vaporisers is without rationale[3]. In spite of technological advance,the amount of vapour produced is calculated based on clinically impractical assumptions. A simple method and formula is suggested for the quick estimate of vapour output, carrier gas flow and determine the splitting ratio while operating a sevoflurane variable bypass vaporizer.
