RESUMEN
Objective To investigate the training effect of CPR for relatives of patients with high-risk sudden cardiac death. Methods 35 patients with sudden cardiac death whose relatives did not re-ceived systematic CPR training were set as the control group, 35 patients of the same kind whose relatives received systematic CPR training were named as the experimental group. The resuscitation effect and emer-gency response time of the two groups were compared and the results underwent t test. Results The re-suscitation effect and emergency response time in the experimental group was obviously better than those of the control group. Conclusions CPR training for the first witness of patients with high-risk sudden cardiac death can significantly increase the pre-hospital rescue rate of sudden cardiac death.
