高频振荡通气（HFOV）的基本特点是利用电机械换能装置产生600～3000次／分的高频振荡电流，通过肺内气体的振荡弥散作用，维持通气。本实验采用不同呼吸参数对实验性呼吸窘迫综合征（ARDS）大模型行高频振荡通气，以观察其效应，为临床提供依据。资料与方法杂种犬12条，雌雄不
High-frequency oscillating ventilation (HFOV) is the basic characteristics of the use of electromechanical transducers to produce 600 ~ 3000 times / min high-frequency oscillation current, through the lungs of the air dispersion of the role of ventilation to maintain ventilation. In this study, high-frequency oscillatory ventilation was performed on the model of experimental respiratory distress syndrome (ARDS) with different respiratory parameters to observe its effect and provide a basis for clinical study.
