The Ohmeda Universal PAC drawover apparatus, a modification of an earlier series of vapour-specific vaporizers, was assessed with regard to its output under varying gas flows and temperatures and its clinical usage with isoflurane and enflurane. The device tended to over-deliver vapour, particularly at low flows and at high temperatures. Its clinical performance during spontaneous and positive pressure ventilation was satisfactory, although adequate concentrations were not achieved using enflurane in the spontaneous ventilation mode. The device was not assessed with ether or halothane. The robust construction, relatively large capacity and thermocompensation make it suitable for field or military anaesthesia.
欧米达通用PAC挥发罐装置是对早期一系列特定蒸汽蒸发器的改进，对其在不同气流和温度下的输出以及异氟烷和恩氟烷的临床使用情况进行了评估。该装置往往会过度输送蒸汽，尤其是在低流量和高温下。尽管在自主通气模式下使用恩氟烷未达到足够浓度，但其在自主通气和正压通气期间的临床性能令人满意。该装置未使用乙醚或氟烷进行评估。其坚固的结构、相对较大的容量和热补偿使其适用于野外或军事麻醉。
