High-frequency jet ventilation was performed on a premature foal for respiratory difficulty attributable to in utero-acquired pneumonia. The procedure involves delivery of compressed gas through a small-bore cannula at frequencies up to 400 cycles/min. Ventilation settings of drive pressure, frequency, and FIO2 were varied to optimize PaO2 and PaCO2 values. The foal was ventilated with this equipment for 14 hours. Evidence of a favorable response to this method of ventilation was observed in the form of improvement in arterial blood gas values as well as the foal's attitude and degree of respiratory effort. High-frequency jet ventilation appears to be a useful method of ventilation for respiratory disease in neonatal foals; however, there remains no clear-cut advantage over conventional positive-pressure ventilation.
对一匹早产马驹进行了高频喷射通气，该马驹因子宫内获得性肺炎而出现呼吸困难。该操作是通过一根细管以高达400次/分钟的频率输送压缩气体。改变驱动压力、频率和吸入氧浓度的通气设置以优化动脉血氧分压（PaO2）和动脉血二氧化碳分压（PaCO2）值。使用该设备对马驹进行了14小时的通气。从动脉血气值的改善以及马驹的状态和呼吸努力程度来看，观察到了对这种通气方法产生良好反应的证据。高频喷射通气似乎是治疗新生马驹呼吸系统疾病的一种有用的通气方法；然而，与传统的正压通气相比，仍没有明显优势。
