摘　　要：北美2B及GS麻醉机的吸气流速（Inspiratory Flow）系手动调节。有较大的调节范围．吸气流速对预设的潮气量有一定的影响，吸气流速的设定应和预设湖气量、呼吸频率、及吸呼比之间有怠好的协调性，过小的吸气流速达不到设定的潮气量，过大的吸气流速将增加不必要的气道压力．每秒的吸气流速和吸气时间的乘积应略大干设定的潮气量。通过一简单方法可以将某一吸气流速的数值大致测定出来．供临床设定时参考。The inspiratory flow rate of North American Narkomed 2B and GS anesthesia machine can be regulated manually in a large adjustment range. It has certain influence on preinstall tidal volume. The setup of inspiratory flow rate should coordinate with the preinstall tidal volume, respiratory rate and I：E ratio. Undersized inspiratory flow rate fails to give the preinstall tidal volume, while the oversized one increases the unwanted airway pressure. The product of inspiratory flow rate per second and inspiratory time should be slightly larger than preinstall tidal volume. The value of inspiratory flow rate can be measured with a simple method, which can be referenced for clinical setting.
