Lifesaver (www.life-saver.org.uk) is an immersive, interactive game that can be used for basic life support training. Users 'resuscitate' a victim of cardiac arrest in a filmed scenario and move their device up and down to simulate cardiac compressions.
Randomised controlled trial of 3 UK schools (81 students) comparing Lifesaver, face-to-face (F2F) training, and a combination of both. Primary outcomes: mean chest compression rate and depth.
flow fraction, CPR performance, and attitude survey. Outcomes measured immediately, 3 and 6 months.
Primary outcomes: Mean chest compression depth was suboptimal in all groups due to body size. F2F performed better than Lifesaver initially (-11.676; 95% CI -18.34 to -5.01; p=0.0001) but no difference at 3 months (p=0.493) and 6 months (p=0.809). No difference in mean compression rates for Lifesaver vs F2F (-11.89; 95% CI -30.39 to -6.61; p=0.280) and combined vs Lifesaver (0.25; 95% CI -17.4 to -17.9; p=0.999).
all groups had flow fraction >60% after training. Combined group performed better for skills assessment than Lifesaver (4.02; 95% CI 2.81-5.22; p=0.001) and F2F (1.76; 95 CI 0.51-3; p=0.003); and the same at 6 months (1.92; 95% CI 0.19-3.64; p=0.026 and 1.96; 95% CI 0.17-3.75; p=0.029).
Use of Lifesaver by school children, compared to F2F training alone, can lead to comparable learning outcomes for several key elements of successful CPR. Its use can be considered where resources or time do not permit formal F2F training sessions. The true benefits of Lifesaver can be realised if paired with F2F training.
Lifesaver(www.life-saver.org.uk)是一款沉浸式互动游戏,可用于基本生命支持培训。用户在拍摄的场景中对心脏骤停的受害者进行复苏,并上下移动设备以模拟心脏按压。
对英国 3 所学校(81 名学生)进行了随机对照试验,比较了 Lifesaver、面对面(F2F)培训以及两者的组合。主要结局指标:平均胸外按压率和深度。
流量分数、CPR 性能和态度调查。立即、3 个月和 6 个月测量结果。
主要结局:由于体型原因,所有组的平均胸外按压深度均不理想。F2F 的初始效果优于 Lifesaver(-11.676;95%CI-18.34 至-5.01;p=0.0001),但 3 个月(p=0.493)和 6 个月(p=0.809)时无差异。Lifesaver 与 F2F 之间的平均压缩率无差异(-11.89;95%CI-30.39 至-6.61;p=0.280),与联合组与 Lifesaver 之间的差异也无统计学意义(0.25;95%CI-17.4 至-17.9;p=0.999)。
所有组在培训后流量分数均>60%。与 Lifesaver 相比,联合组在技能评估方面的表现优于 Lifesaver(4.02;95%CI2.81-5.22;p=0.001)和 F2F(1.76;95CI0.51-3;p=0.003),6 个月时也是如此(1.92;95%CI0.19-3.64;p=0.026 和 1.96;95%CI0.17-3.75;p=0.029)。
与单独的 F2F 培训相比,将 Lifesaver 用于学童,可在几个成功 CPR 的关键要素方面实现可比较的学习结果。如果资源或时间不允许进行正式的 F2F 培训,则可以考虑使用 Lifesaver。如果将 Lifesaver 与 F2F 培训结合使用,则可以实现其真正的益处。
