Abstract:

Background

Locations concentrated with High School (HS) students tend to have lower out-of-hospital cardiac arrest (OHCA) survival rates. Mobile applications (apps) have the capability to augment cardiopulmonary resuscitation (CPR) skill retention as a low-cost, accessible training method.

Methods

An iterative process to develop an app to reinforce CPR skills emphasizing hand placement, compression rate, real-time feedback, and recurring tips is described. The app was tested on HS students to measure its impact on quality and comfort of CPR using Likert surveys and skills assessments before and after one month of usage. CPR Score and compression rate were measured using the Laerdal™ Little Anne Manikin QCPR software.

Results

Fourteen HS students participated in a prospective observational study. It was found that the use of the developed app was associated with improved CPR performance (80.43% v. 87.86%, p=0.01-0.02, 95% CI=2.20-12.66) after one month. Additionally, improvements were demonstrated in compression rate accuracy (21.43% v. 64.29%, p=0.041, 95% CI=0.132-0.725), increased comfort performing CPR (3.86 v. 4.79, p<0.001, 95% CI =0.99-1.00) and comfort performing CPR on strangers (2.71 v. 4.42, p<0.001, 95% CI=1.24-2.19). In addition, for every time the app was used, CPR performance increased by 0.5668% (p=0.0182).

Conclusion

Findings suggest that mobile apps may have promising implications as augmentative tools for CPR curriculums.

用于高中生心肺复苏技能保留的交互式移动应用程序的迭代开发和测试：一项试点研究

摘要：

背景

在高中 (HS) 学生集中的地方，院外心脏骤停 (OHCA) 的存活率往往较低。移动应用程序（应用程序）能够将心肺复苏 (CPR)技能保留作为一种低成本、可访问的培训方法。

方法

描述了开发应用程序以加强 CPR 技能的迭代过程，强调手部放置、压缩率、实时反馈和重复提示。该应用程序在 HS 学生身上进行了测试，以在使用一个月前后使用李克特调查和技能评估来衡量其对 CPR 质量和舒适度的影响。使用挪度™ Little Anne Manikin QCPR 软件测量 CPR 分数和按压率。

结果

十四名 HS 学生参加了一项前瞻性观察研究。发现使用开发的应用程序与 1 个月后 CPR 性能的提高有关（80.43% 对 87.86%，p=0.01-0.02，95% CI=2.20-12.66）。此外，按压率准确性也得到了改善（21.43% 对 64.29%，p=0.041，95% CI=0.132-0.725），提高了 CPR 的舒适度（3.86 对 4.79，p<0.001，95% CI =0.99- 1.00）和对陌生人进行心肺复苏术的舒适度（2.71 对 4.42，p<0.001，95% CI=1.24-2.19）。此外，每次使用该应用程序时，CPR 性能都会提高 0.5668% (p=0.0182)。

结论

研究结果表明，移动应用程序作为 CPR 课程的辅助工具可能具有广阔的应用前景。
