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。

Objective To discuss the effect of different mechanical ventilation parameters on intra-abdominal pres-sure. Methods A total of 42 cases with mechanical ventilation suffering from chronic obstructive pulmonary diseases (COPD) and respiratory failure were selected for observing the effects of inspiratory platform time (Tplat), inspiratory time (Ti) and end-expiratory pressure (PEEP) on intra-abdominal pressure. Results In SIMV+PSV ventilation mode, changes of Tplat and Ti had no significant effects on intra-abdominal pressure (P>0.05). There were no significant differences be-tween SIMV+PEEP0 and base line values (P>0.05). Conclusion The alteration of peep has a great influence in intra-ab-dominal pressure, which suggests the importance of selecting proper mechanical ventilation parameters.
