Abstract

一种医用通气系统(1000)，包括输入设备(10)、第一气源接口(11)、第二气源接口(12)、呼吸回路(13)、驱动气体支路(14)、新鲜气体支路(15)、通气控制器(16)；通气控制器(16)，根据输入设备(10)接收到的第一模式控制信息，控制驱动气体支路(14)经呼吸回路(13)为患者提供通气支持，控制新鲜气体支路(15)向呼吸回路(13)输出含麻药的新鲜气体；或通气控制器(16)，根据输入设备(10)接收到的第二模式控制信息，控制驱动气体支路(14)向呼吸回路(13)输出第一气体，控制新鲜气体支路(15)向呼吸回路(13)输出第二气体。在保持现有技术医用通气系统的常规麻醉功能下，当选择第二模式时，能够实现高流速给氧功能，不需要改变现有的连管方式，有效降低现有技术高流速给氧设备的复杂性。
