Bystander training in cardiopulmonary resuscitation (CPR) is crucial to improve the victims' survival and quality of life after sudden cardiac arrest. This observational study aimed to determine the success rate of 2 different programs of CPR training for children, adolescents, and adults in school communities. We assessed the development and acquisition of the following CPR skills: checking local safety, assessing victim's responsiveness, calling for help, assessing victim's breathing, and performing chest compression (hands and straight arms placement on the chest, compression velocity, depth, and chest release) using a 40-minute program with handmade manikins or the 120-minute program using intermediate-fidelity manikins. There were 1,630 learners (mean age 16 years, 38% male) in the 40-minute program, and 347 learners (mean age 27 years, 32% male) in the 120-minute program. The lowest successful pass rate of learners that developed CPR skills was 89.4% in the 40-minute program and 84.5% in the 120-minute program. The chances of success increased with age in the same program (compression rate and depth). The success rate also increased with the more extended and intermediate-cost program at the same age (assessing victim's responsiveness, calling for help, and assessing the victim's respiration). In conclusion, a 40-minute and cheaper (low-cost handmade manikin) CPR program was adequate to develop and acquire the overall CPR skills for ≥89% at school communities, independently of gender. However, some individual CPR skills can be further improved with increasing age and using the longer and intermediate-cost program.
旁观者心肺复苏（CPR）培训对于提高心搏骤停后患者的生存率和生活质量至关重要。本观察性研究旨在确定两种不同的学校社区儿童、青少年和成人 CPR 培训计划的成功率。我们评估了以下 CPR 技能的发展和掌握情况：检查当地安全性、评估受害者反应能力、呼救、评估受害者呼吸情况以及进行胸外按压（双手和直臂置于胸部、按压速度、深度和胸部释放）。使用 40 分钟的手工制作模拟人或 120 分钟的中等保真度模拟人进行培训。40 分钟课程有 1630 名学习者（平均年龄 16 岁，38%为男性），120 分钟课程有 347 名学习者（平均年龄 27 岁，32%为男性）。掌握 CPR 技能的学习者中，成功率最低的是 40 分钟课程的 89.4%和 120 分钟课程的 84.5%。在同一课程中，学习者的成功率随着年龄的增长而增加（按压速度和深度）。在同一年龄，成功率也随着课程时间的延长和成本的增加而增加（评估受害者反应能力、呼救和评估受害者呼吸）。总之，40 分钟的课程和更便宜的（低成本手工制作模拟人）CPR 课程足以在学校社区中发展和掌握总体 CPR 技能，成功率≥89%，而与性别无关。然而，一些个别 CPR 技能可以通过增加年龄和使用更长和中等成本的课程进一步提高。
