摘要：

【摘要】目的 探讨机械通气状态下不同参数变化对腹腔压力的影响。方法 选取慢性阻塞性肺疾病（COPD）伴呼吸衰竭行机械通气的42例患者，当患者病情稳定后，在同步间歇指令通气（SIMV）+压力支持通气（PSV）的通气模式下，观察吸气平台时间（Tplat）、吸气时间（Ti）、呼气末正压（PEEP）的变化对腹腔压力的影响。结果在 SIMV+PSV通气模式下，Tplat、Ti的变化对腹腔压力无明显影响（P>0.05）。SIMV+PEEP0与基线值比较差异无统计学意义（P>0.05），随着PEEP的增加，腹腔压力随之升高（P＜0.05）。结论机械通气状态下，呼气末正压的变化将会对腹腔压力产生显著影响。选择合理的机械通气参数至关重要。

Abstract: [Abstract] Objective To discuss the effect on intra-abdominal pressure by different mechanical ventilation parameters. Methods 42 cases with mechanical ventilation suffering from chronic obstructive pulmonary diseases and respiratory failure were selected for observing the effects on intra-abdominal pressure by changing Tplat, Tis and peep. Results Compared with Tplat and Tis, the change of peep has much more effect on intra-abdominal pressure, both in SIMV and PSV. Conclusion The alteration of peep has a great influence on intra-abdominal pressure ,which increases the importance of selecting proper mechanical ventilation parameters.
