Title: Chest compression only CPR
题目：只有心脏按压的心肺复苏
Author作者: SemharTewelde

• Early CPR performed by laypersons can double the chances of survival in out-of-hospital cardiac arrest (OHCA)
• 在医院前心脏骤停中，早期非医护人员心肺复苏能使生存率翻一番。
•
• A retrospective cohort that combined 2 RCT compared the survival effects of dispatcher CPR instruction consisting of chest compression alone or chest compression with rescue breathing
• 一个回顾性的临床报告，对两个随机临床实验进行了总结，比较了在调度员心肺复苏指导下的只有心脏按压或心脏按压与通气同时进行的效果。
•
• There was a lower risk of death after adjustment for confounders (adjusted hazard ratio 0.91, 95% confidence interval 0.83-0.99, p=0.02)
• 在对影响因素进行调整后，（只有心脏按压组）死亡率明显降低（调整后的危险比为0.91，95％置信区间为0.83－0.99，p＝0.02）。
•
• Findings strongly support a long-term mortality benefit of dispatcher CPR instruction strategy consisting of chest compression alone rather than chest compression plus rescue breathing
• 结果证实，由调度员指导下的只有心脏按压方案，而不是心脏按压和通气同步进行方案，有益于降低长期死亡率。
