The objections to using adult circle systems on very small patients include increased resistance to breathing, mechanical dead space, and slow equilibration times. These objections warrant consideration before assuming that nonrebreathing systems have an inherent advantage for patients between 3 and 10 kg. The cost of anesthesia and the time taken to establish a desired anesthetic level are as important in determining which system to use for small animal patients. Based on the current evidence, it is acceptable to use adult circle rebreathing systems on healthy patients as small as 3 kg.
在极小的患者身上使用成人循环系统存在一些问题，包括呼吸阻力增加、机械死腔和平衡时间延长。在认定非再呼吸系统对3至10千克的患者具有固有优势之前，这些问题值得考虑。在确定为小动物患者使用哪种系统时，麻醉成本和达到所需麻醉水平所需的时间同样重要。根据目前的证据，对于低至3千克的健康患者，使用成人循环再呼吸系统是可以接受的。
