If adolescents can teach each other cardiopulmonary resuscitation (CPR) during school hours, this may be a cost-effective approach to CPR training. The aim of this study was to evaluate CPR quality among students trained by student instructors in CPR.
Three high schools participated. Recruited student instructors (SIs) were given a two-day course by professional instructors. Theoretic knowledge was acquired through an e-learning program. The SIs then trained fellow students in a 90-minute practical CPR session during physical education classes. All participants performed a 4-minutes test of CPR performance. Data was collected using Little Anne QCPR manikins with QCPR classroom software (Laerdal Medical Inc, Norway). Statistical equivalence in CPR performance was assessed applying the two one-sided tests (TOST)-procedure.
Eight professional instructors trained 76 SIs who trained approximately 2650 students in CPR. The number of available tests for analysis of student performance was 982. The compression rates were within guideline recommendations for SIs (mean 110.6, SD 5.4) and students (mean 118.6, SD 8.6). The corresponding numbers for mean compression depth were 7.2 cm (SD 0.7) and 7 cm (SD 1.0). Students demonstrated greater variation in mouth-to-mouth (MTM) skills, with only 41% performing at least 15 successful ventilations during the test. Except for the total number of MTM ventilations (mean difference -5.6), CPR performance was deemed statistically equivalent between professional instructors, SIs and students.
High school students can be trained as CPR instructors and teach fellow students CPR with good quality, with some variation in MTM-ventilation skills.
如果青少年能够在上课时间互相教授心肺复苏术（CPR），这可能是一种具有成本效益的CPR培训方法。本研究的目的是评估由学生教员培训的学生的CPR质量。
三所高中参与了研究。招募的学生教员（SI）接受了专业教员为期两天的课程培训。理论知识通过电子学习程序获取。然后，SI在体育课期间用90分钟的时间对同学进行CPR实践培训。所有参与者都进行了4分钟的CPR操作测试。使用配备QCPR课堂软件的Little Anne QCPR人体模型（挪威Laerdal Medical Inc公司）收集数据。应用双向单侧检验（TOST）程序评估CPR操作的统计等效性。
8名专业教员培训了76名SI，这些SI又培训了约2650名学生进行CPR。可用于分析学生操作的测试数量为982次。SI的按压频率（平均110.6，标准差5.4）和学生的按压频率（平均118.6，标准差8.6）均在指南建议范围内。平均按压深度的相应数值分别为7.2厘米（标准差0.7）和7厘米（标准差1.0）。学生在口对口（MTM）技能方面表现出更大的差异，测试期间只有41%的学生至少成功进行了15次通气。除MTM通气总数外（平均差异-5.6），专业教员、SI和学生之间的CPR操作在统计学上被认为是等效的。
高中生可以被培训成为CPR教员，并以高质量教授同学CPR，不过在MTM通气技能方面存在一些差异。
