【摘要】：目的探讨COPD患者机械通气时选择不同通气模式下,人机同步性及舒适性的比较。为COPD病人探索更适宜的通气方案。方法选择80例行有创机械通气的COPD患者,分为神经调节辅助通气(NAVA)组17例、适应性支持通气组(ASV)33例、实施压力控制通气-压力支持的常规对照组30例。在保持分钟通气量基本相似的情况下,对比所有组患者的呼吸力学指标、血气指标和血流动力学指标,并采用量表分析患者上机时的呼吸机不合拍程度(人机对抗率)。结果各组患者的年龄、性别、APACHEⅡ评分结果无差异;NAVA组患者指令呼吸频率较低,NAVA组和ASV组患者的潮气量均比对照通气组大,P值均0.05。量表评估NAVA、ASV、对照组的人机对抗率分别为29.4%(5/17)、21.2%(7/33)、40%(12/30),差异显著(P0.01)。结论 NAVA和ASV通气均可保持较好的自主呼吸,降低人机对抗率,是符合COPD患者需要的通气模式。
[Abstract]:Objective to explore the comparison of man-machine synchrony and comfort under different ventilation modes in patients with COPD. To explore a more suitable ventilation scheme for COPD patients. Methods 80 COPD patients with invasive mechanical ventilation were divided into (NAVA) group (n = 17), (ASV) group (n = 33) and control group (n = 30). The respiratory mechanics indexes, blood gas indexes and hemodynamic indexes of all patients were compared with each other while the minute ventilation volume was basically similar, and the degree of mechanical ventilation (man-machine antagonism) was analyzed by using the scale when the patients were on the machine. Results there was no difference in age, sex and Apache 鈪，
