摘　　要：[目的]探讨胸外按压频率及按压者的身高、体重、年龄对按压质量的影响,以便确定最佳按压频率,为高品质胸外心脏按压培训提供依据。[方法]对2013年9月我院招聘的192名新护士进行为期3d的心肺复苏相关理论及技能的培训后,将其随机分为6组,其中1个自由按压组,5个引导组。自由按压组在没有任何频率指引的情况下,在心肺复苏按压模型上实施2min的胸外按压,5个引导组分别在节拍器引导的80/min、100/min、110/min、120/min、140/min的频率下实施2 min的胸外按压。按压过程中使用Laerdal计算机技能报告系统监测并记录各项质量指标数据,然后使用单因素方差分析、非参数检验、相关及回归分析对数据进行分析。[结果]最终纳入研究对象186人,6组间的按压深度、足够按压深度次数所占比例、下压/上放比例以及疲劳时间差异有统计学意义(P<0.05),且保证最好按压质量的按压频率是100/min;按压者的体重与正确按压次数所占比例、按压深度、足够按压深度次数所占比例、下压/上放比例以及疲劳时间呈正相关(P<0.05)。[结论]节拍器能按照设置引导频率稳定的胸外按压,且100/min的按压频率比其他频率更能保证足够的按压深度、延长按压者的疲劳时间;按压者的体重对按压质量有一定影响。Objective:To probe into the influence of frequency of chest compressions and height,weight and age of the presser on the compressions quality,in order to determine the best pressing frequency,so as to provide the basis for training of high quality chest compressions.Methods:A total of 1 92 new nurses who were recrui-ted in September in 2013 were given the cardiopulmonary resuscitation(CPR)related theories and skills training for three days,and they were randomly divided into 6 groups,including a free pressing group and five leading groups.The nurses in free pressing group carried out the chest compressions for 2 min on the cardiopulmonary resuscitation press model,without any frequency guidance.The nurses in five leading groups carried out chest compressions for 2 min under the frequency in metronome guide 80/min,100/min,110/min,120/min and 140/min. During the compressions,Laerdalcomputer skills reporting system was used to monitor and record the quality indexes data,and then to analyze the data by using the single factor analysis of variance,non parametric test, correlation and regression analysis.Results:Totally 186 cases were included in a study,there were statistically significant difference in press depth,proportion of enough pressing depth numbers,down press/up release pro-portion and fatigue time among 6 groups(P <0.05),and the press frequency which can ensure the best press quality was 100/min;presser’s weight was positively correlated with proportion of correct press number,press depth,proportion of number of enough press depth,down press/up releasing ratio and fatigue time(P <0.05). Conclusion:The metronome can guide the chest compression with frequency stabilization according to the set-ting.Compared with the other frequency 100/min pressing frequency can guarantee enough press depth and ex-tend the presser’fatigue time;the presser’s weight has certain influence on press quality.
