呼气末二氧化碳分压在心肺复苏中的应用

End-tidal carbon dioxide partial pressure during cardiopulmonary resuscitation

目的:探讨呼气末二氧化碳分压(PETCO2)在心肺复苏(CPR)中的临床意义。方法:选取本院急诊科发生心跳骤停并符合入选标准患者54例,依据复苏是否恢复自主循环分为初始复苏成功组和失败组,监测CPR过程中PET-CO2的变化。结果:21例患者初始复苏成功;复苏成功组和失败组复苏即刻PETCO2水平差异无统计学意义(P<0.05)。两组患者PETCO2水平在复苏开始后5、10min以及20min时比较,差异有统计学意义(P<0.01)。结论:PETCO2水平与心跳骤停患者心肺复苏的预后相关。

Objective：To investigate the end-tidal carbon dioxide partial pressure （PETCO2） in cardiopulmonary resuscitation （CPR） in clinical significance.Methods：The hospital emergency department cardiac arrest and 54 patients met the inclusion criteria,based on the recovery of spontaneous circulation is restored into the initial resuscitation group and the failure group to monitor the changes PETCO2 during CPR.Results：21 patients with initial resuscitation;resuscitation immediate resuscitation group and the failure was no significant difference PETCO2 levels （P〈0.05）.PETCO2 two groups of patients in the recovery after the start of the level of 5,10 min and 20 min time,the difference was statistically significant （P〈0.01）.Conclusion：PETCO2 level of CPR in patients with cardiac arrest prognosis.
