The utility of peak nasal inspiratory flow rate for clinical practice 鼻腔最大吸气流量在临床中的应用
Objective : To find out whether peak nasal inspiratory flow rate ( PnIFR ) of one side nose can indicate nasal patency. 目的:探讨测量单侧鼻腔最大吸气流量(PnIFR)的方法及其临床价值。
Conclusion Large volume ventilation with high inspiratory flow 、 high respiratory rate could produce severe lung injury. 结论大潮气量、高吸气流速(IFR)、高通气频率机械通气可导致严重的肺损伤,降低通气频率,可适当的减轻这类损伤。
Common form of the pressure switch, volume switch, time switch and flow switch, that is, to achieve the preset inspiratory pressure, capacity, time or flow rate is converted to breath. 常见的方式有压力切换、容量切换、时间切换和流速切换,即吸气达到预置的压力、容量、时间或流速则转为呼气。
