目的 探讨对心脏骤停患者应用呼气末二氧化碳分压（PETCO2）检验对心肺复苏结局判断中的临床结果和作用。方法? 选取苏州市相城人民医院 2017 年 1 月至 2019 年 12 月收治的 120 例进行心肺复苏的心脏骤停患者作为研究对象，采用随机数字表法分为常规组（60 例）与研究组（60 例）。常规组患者不进行 PETCO2 检测，研究组患者进行 PETCO2 检测。比较两组患者的心肺复苏持续时间、自主循环恢复率、PETCO2 水平及满意度等指标。结果? 研究组患者在心肺复苏持续时间上显著短于常规组，而自主循环恢复率和临床满意度均高于常规组，且研究组中恢复自主循环患者在初始、平均及终末阶段的 PETCO2 水平均高于未恢复自主循环患者，组间比较差异有统计学意义（P＜0.05）。结论? 对心脏骤停患者进行心肺复苏抢救时采用 PETCO2检测，能够更好地把控抢救状况，缩短抢救时间，提高抢救效果，增加患者的满意度，具有较高的临床应用价值。
Objective To investigate the clinical results and effects of end-expiratory carbon dioxide（PETCO2）test on the outcome of cardiopulmonary resuscitation（CPR）in patients with cardiac arrest. Methods? A total of 120cases of cardiac arrest patients undergoing cardiopulmonary resuscitation（CPR）in Xiangcheng People's Hospital from January 2017 to December 2019 were selected as the research subjects，and divided into routine group（60 cases）and study group（60 cases）by random number table method. Patients in the conventional group were not tested for PETCO2，while patients in the study group were tested for PETCO2. The duration of cardiopulmonary resuscitation，recovery rate of autonomous circulation，PETCO2 level and satisfaction were compared between the two groups. Results? The duration of cardiopulmonary resuscitation in the study group was significantly shorter than that in the conventional group，and the recovery rate of spontaneous circulation and clinical satisfaction were higher than those in the conventional group，and the PETCO2 levels in the initial，average and final stages of patients with spontaneous circulation in the study group were higher than those in the patients without recovery of spontaneous circulation，the difference between groups was statistically significant（P ＜ 0.05）. Conclusion? PETCO2 detection can better control the rescue status，shorten the rescue time，improve the rescue effect，increase patient satisfaction，and it has high clinical application value.
