Currently, a mechanical ventilator that can be adapted to the Universal Portable Anesthesia Complete (UPAC) vaporizer and anesthetic delivery system does not exist. The need for the anesthetist to concentrate on drug delivery and fluid resuscitation for the combat casualty in the field setting provides an expedient for the adaptation of a ventilator to the UPAC system. The purpose of this study was to determine whether the performance of the UPAC vaporizer was significantly altered when mechanical ventilation was provided in a drawover versus a pushover configuration, and to provide vaporizer performance curves for ventilatory parameters common for mechanical ventilation. The Ohio V5A and Lifecare PLV-100 ventilators were used in controlled benchwork analysis. The results of the comparison between the two ventilators indicated that there was no significant difference in vaporizer output between drawover and pushover configurations. The data indicated that vaporizer output could be reliably predicted in either mode and was correlated with tidal volume and respiratory rate.
目前，尚不存在一种可适配通用便携式麻醉全套装置（UPAC）蒸发器和麻醉输送系统的机械通气机。在战地环境中，麻醉师需要专注于为战斗伤员进行药物输送和液体复苏，这为将通气机适配到UPAC系统提供了便利。本研究的目的是确定在采用吸入式与推注式配置进行机械通气时，UPAC蒸发器的性能是否会发生显著变化，并提供机械通气常见通气参数的蒸发器性能曲线。在对照性实验台分析中使用了俄亥俄V5A和生命关怀PLV - 100通气机。两种通气机之间的比较结果表明，吸入式和推注式配置下蒸发器输出量没有显著差异。数据表明，在两种模式下蒸发器输出量均可可靠预测，且与潮气量和呼吸频率相关。
