The BAIN circuit was studied in 11 patients undergoing maxillofacial surgery, with no respiratory deficit, and under spontaneous and assisted ventilation, with a rate of flow of gas of 80, 100, 120, 140 ml/kg/min. From the results it could be concluded that this circuit should be used with a flow of at least 140 ml/kg/min, in assisted ventilation, in order to avoid any retention of CO2. Capnographic follow-up enabled better regulation of the flow rate necessary.
对11例接受颌面外科手术、无呼吸功能不全且处于自主通气和辅助通气状态、气体流速为80、100、120、140毫升/千克/分钟的患者的BAIN回路进行了研究。从结果可以得出结论，为避免二氧化碳潴留，在辅助通气时，该回路应以至少140毫升/千克/分钟的流速使用。二氧化碳图监测有助于更好地调节所需的流速。
