Cardiopulmonary resuscitation (CPR) training has traditionally involved classroom-based courses or, more recently, home-based video self-instruction. These methods typically require preparation and purchase fee; which can dissuade many potential bystanders from receiving training. This study aimed to evaluate the effectiveness of teaching compression-only CPR to previously untrained individuals using our 6-min online CPR training video and skills practice on a homemade mannequin, reproduced by viewers with commonly available items (towel, toilet paper roll, t-shirt).
Participants viewed the training video and practiced with the homemade mannequin. This was a parallel-design study with pre and post training evaluations of CPR skills (compression rate, depth, hand position, release), and hands-off time (time without compressions). CPR skills were evaluated using a sensor-equipped mannequin and two blinded CPR experts observed testing of participants.
Twenty-four participants were included: 12 never-trained and 12 currently certified in CPR. Comparing pre and post training, the never-trained group had improvements in average compression rate per minute (64.3 to 103.9, p = 0.006), compressions with correct hand position in 1 min (8.3 to 54.3, p = 0.002), and correct compression release in 1 min (21.2 to 76.3, p < 0.001). The CPR-certified group had adequate pre and post-test compression rates (>100/min), but an improved number of compressions with correct release (53.5 to 94.7, p < 0.001). Both groups had significantly reduced hands-off time after training. Achieving adequate compression depths (>50 mm) remained problematic in both groups. Comparisons made between groups indicated significant improvements in compression depth, hand position, and hands-off time in never-trained compared to CPR-certified participants. Inter-rater agreement values were also calculated between the CPR experts and sensor-equipped mannequin.
A brief internet-based video coupled with skill practice on a homemade mannequin improved compression-only CPR skills, especially in the previously untrained participants. This training method allows for widespread compression-only CPR training with a tactile learning component, without fees or advance preparation.
传统上，心肺复苏术（CPR）培训包括基于课堂的课程，或者最近出现的家庭视频自学。这些方法通常需要准备工作和购买费用，这可能会使许多潜在的旁观者放弃接受培训。本研究旨在评估使用我们6分钟的在线CPR培训视频，并通过观众用常见物品（毛巾、卫生纸卷、T恤）自制的人体模型进行技能练习，对从未接受过培训的人员进行仅按压式CPR教学的效果。
参与者观看培训视频，并使用自制人体模型进行练习。这是一项平行设计的研究，对CPR技能（按压频率、深度、手部位置、放松）和放手时间（无按压时间）进行培训前和培训后的评估。使用配备传感器的人体模型评估CPR技能，两名盲法CPR专家观察参与者的测试情况。
纳入了24名参与者：12名从未接受过培训，12名目前持有CPR证书。比较培训前后，从未接受过培训的组每分钟平均按压频率有所提高（从64.3次提高到103.9次，p = 0.006），1分钟内手部位置正确的按压次数（从8.3次提高到54.3次，p = 0.002），以及1分钟内正确按压放松的次数（从21.2次提高到76.3次，p < 0.001）。持有CPR证书的组在测试前和测试后的按压频率均足够（>100次/分钟），但正确放松的按压次数有所增加（从53.5次提高到94.7次，p < 0.001）。两组在培训后放手时间均显著减少。两组在达到足够的按压深度（>50毫米）方面仍然存在问题。组间比较表明，与持有CPR证书的参与者相比，从未接受过培训的参与者在按压深度、手部位置和放手时间方面有显著改善。还计算了CPR专家与配备传感器的人体模型之间的评分者间一致性值。
一段简短的基于互联网的视频，再加上在自制人体模型上进行技能练习，可提高仅按压式CPR技能，尤其是在之前未接受过培训的参与者中。这种培训方法允许进行广泛的仅按压式CPR培训，带有触觉学习成分，无需费用或提前准备。
