高频通气( high frequency ventilation,HFV) 是应用小于或等于解剖死腔的潮气量,以高的通气频率 ( 通气频率≥正常 4 倍以上) ,在较低的气道压力下进行通气的一种特殊的通气方法。美国食品与药品管理局( FDA) 将 HFV 定义为频率 > 150 次/min 或 2. 5 Hz( 1 Hz = 60 次 / min) 的辅助通气。HFV 基于呼吸机在气道内产生的高频压力/气流变化及呼气是主动还是被动等特点而分为高频喷射通气 High frequency ventilation (HFV) is the use of less than or equal to the tidal volume of anatomical dead space, with high ventilation frequency (ventilation frequency ≥ 4 times more than normal), a lower airway pressure ventilation Special ventilation method. The U.S. Food and Drug Administration (FDA) defines HFV as assisted ventilation at frequencies> 150 beats / min or 2.5 hertz (1 Hz = 60 beats / min). HFV is divided into high-frequency jet ventilation based on the high-frequency pressure / airflow changes in the airway and whether the exhalation is active or passive
