目的 探讨基于遗忘曲线的线下+线上心肺复苏培训在社区居民中的应用效果。方法 方便选取3个社区的居民开展心肺复苏公益培训。首先进行线下集中理论和技能培训,然后根据遗忘曲线依次在第1天、第2天、第4天、第6天、第15天、第30天、第60天、第90天开展线上培训,包括微视频及心肺复苏教育游戏。分别在培训前、线下培训后及线上培训后对社区居民进行理论考核及心肺复苏能力自我评价,在线下培训后及线上培训后进行技能考核。 结果 共67名居民参与全程培训并完成考核。经趋势卡方检验,培训后社区居民的心肺复苏各条目理论知识的正确情况呈线性提高（P<0.05）。线下培训后社区居民的技能考核成绩为（7.88±1.30）分,线上培训后为（8.03±1.38）分。培训后社区居民认为自己能够正确实施心肺复苏技术的比例由培训前的6%（4/67）提升到100%（67/67）。 结论 基于遗忘曲线的线下+线上心肺复苏培训可提升社区居民的心肺复苏知识及技能,增加居民实施急救的意愿及急救行为。

Objective To explore the effects of a offline + online cardiopulmonary resuscitation（CPR） training based on forgetting curve in community residents. Methods Residents in 3 communities were recruited by convenience sampling and CPR training was conducted among these residents. First off-line intensive theoretical and skill training was carried out. The online training was then provided on the 1st day,2nd day,4th day,6th day,15th day,30th day,60th day,and 90th day. The online-training included micro-videos and CPR educational games. The CPR knowledge and self-rated CPR ability were assessed before the training,after the offline training and after the online training. The CPR skills were evaluated after the offline training and the online training. Results A total of 67 residents participated in the whole training and completed the assessment. According to the trend chi-square test,after the training,the correctness of the theoretical knowledge of each item of CPR increased linearly among the community residents（P<0.05）. The skill assessment score of community residents after offline training was（7.88±1.30）,and after online training it was（8.03±1.38）. The proportion of community residents who believed that they could do CPR correctly increased from 6%（4/67） before the training to 100%（67/67） after the training. Conclusion The application of offline + online CPR training based on forgetting curve can improve the CPR knowledge and skills of community residents and increase residents’ willingness and behavior to perform first aid.
