To describe the quality of chest compressions performed by secondary-school students trained with a realtime audiovisual feedback system.
The learners were 167 students aged 12 to 15 years who had no prior experience with cardiopulmonary resuscitation (CPR). They received an hour of instruction in CPR theory and practice and then took a 2-minute test, performing hands-only CPR on a child mannequin (Prestan Professional Child Manikin). Lights built into the mannequin gave learners feedback about how many compressions they had achieved and clicking sounds told them when compressions were deep enough.
All the learners were able to maintain a steady enough rhythm of compressions and reached at least 80% of the targeted compression depth. Fewer correct compressions were done in the second minute than in the first (P=.016).
Real-time audiovisual feedback helps schoolchildren aged 12 to 15 years to achieve quality chest compressions on a mannequin.
描述使用实时视听反馈系统培训的中学生进行胸外按压的质量。
学习者为167名年龄在12至15岁之间、此前无心肺复苏（CPR）经验的学生。他们接受了一小时的CPR理论与实践指导，然后进行了一次2分钟的测试，在儿童人体模型（普雷斯丹专业儿童人体模型）上进行仅胸外按压的CPR操作。人体模型内置的灯光向学习者反馈他们完成的按压次数，咔嗒声则在按压深度足够时告知他们。
所有学习者都能够保持足够稳定的按压节奏，且达到至少80%的目标按压深度。第二分钟完成的正确按压次数少于第一分钟（P = 0.016）。
实时视听反馈有助于12至15岁的学童在人体模型上进行高质量的胸外按压。
