智能反馈装置对心肺复苏培训近期和远期效果的影响

目的探讨应用智能反馈装置对心肺复苏培训效果和远期技能保持的影响。方法研究共纳入142名研究对象,完成2015 AHA指南的单人成人心肺复苏指南的培训。培训完成后所有参与者随机分为反馈组和对照组。分组完成后在BLS导师指导下再进行CPR练习,对照组导师主要指导参与者提高CPR质量,反馈组导师除指导参与者提高CPR质量外,还要向参与者讲解反馈装置的使用,直至熟练操作。在完成操作练习后和1个月后组织所有参与者进行无反馈CPR考核。心肺复苏培训质量是通过心肺复苏的正确率平均按压深度、频率、胸廓回弹,按压指数和有效通气来定量。结果142名研究对象均完成此实验。反馈组的CPR培训质量高于对照组,差异有统计学意义(P<0.05);1个月后反馈组CPR质量较培训即刻后无显著下降,而对照组则有显著下降。结论智能反馈装置有助于提升心肺复苏培训质量和心肺复苏技能的保持。

Effect of intelligent feedback device on the short-term and long-termeffects of cardiopulmonary resuscitation training

Objectives To explore the effect of intelligent feedback device on training effect and long-term skill mainte-nance of cardiopulmonary resuscitation(CRP).MethodsA total of 142 subjects were enrolled in the study and complet-ed the training of 2015 AHA guidelines for single adult cardiopulmonary resuscitation.After the training,all partici-pants were randomly divided into the feedback group and the control group.And than the CPR exercise will be conduct-ed under the guidance of BLS tutors.The tutors in the control group will mainly guide the participants to improve theCPR quality.In addition to guiding the participants to improve the CPR quality,the tutors in the feedback group will al-so explain the use of the feedback device to the participants until they are proficient in the operation.CPR quality wasdetermined after practices completed immediately and retested at I month.The training quality of CPR was evaluatedby the correct rate of CPR(mean press depth,frequency,chest rebound,press index and effective ventilation).ResultsAll 142 subjects completed the experiment.The quality of CPR training in the feedback group was higher than that inthe control group,the difference was statistically significant(P<0.05).After one month,the quality of CPR in the feed-back group was not significantly lower than that immediately after training,while that in the control group was signifi-cantly lower.Conclusion The intelligent feedback device can help to improve the quality of CPR training and themaintenance of CPR skills.
