| 摘 要： | 用相关和回归处理方法,研究了8条正常狗咽喉部高频喷射通气时,调节驱动压、呼吸比和频率对喷气量、吸入气氧浓度、动脉血气及气道内压的作用。结果显示,驱动压和呼吸此对各观察指标几乎有同等重要的作用,频率的影响很小,喷气量与吸入气氧浓度、动脉血气、气道内压间存在显著的正相关关系。说明调节参数的意义主要在于改变了喷气量。

| Abstract: | 8 normal dogs were subjected to trans-laryngopharynx high frequency jet ventilation (LP -HFJV) to investigate the effects of driving pressure(DP), inspiratory / expiratory ratio(I : E) and frequency(f) on the jet gas volume(JGV), inspired oxygen fraction(Fio2), arterial blood gases and airway pressure. Linear regression analyses showed both DP and I : E were the determinants of the variables. There were significant correlations between JGV and Fio2, Pao2, Paco2, mean airway pressure and positve expiratory end pressure. The significance of regulation of the parameters during LP-HFJV mainly lies in the alteration of the jet gas volume. |
