摘要
目的:评估经胸阻抗变化(TTI)在预测胸外按压质量中的价值。方法:纳入21名确诊院外心跳骤停患者,所有患者按照Utsteins模式记录数据,同时通过除颤仪采集按压深度、频率、呼气末CO_2及TTI。结果:21名患者均未能恢复自主循环。随着复苏时间延长,施救者按压质量出现下降。TTI在复苏早期与按压深度及呼气末CO_2呈明显正相关。结论:心肺复苏早期TTI可以较好预测按压深度及冠脉血流情况,可作为院外条件下监测按压质量的选择。
Objective： To evaluated the application of transthoracic impedance（TTI） in monitoring quality of chest compression. Methods： Twenty one cardiac arrest victims were included in this study. All data was recorded in form of Utsteins, and values of compression depth, frequency, end-tidal carbon dioxide and TTI were recorded. Results： No victims were survival to discharge. The quality of compression was attenuated while a long-time resuscitation was performed. It indicated that there was a strong positive relationship between TTI and compression depth and end-tidal carbon dioxide.Conclusion： TTI is better to predict compression depth and furthermore coronary artery perfusion in early stage of resuscitation, therefore, it might become a choice for compression quality monitoring in the setting of prehospital rescue.
