背景：目前心肺复苏 (CPR) 课程的 4 小时课程长度是广泛传播 CPR 培训的障碍。基于视频的自学 (VSI) 的有效性已在多项研究中得到证明；然而，这种方法对老年人的有效性尚不确定。尽管老年人最有可能目睹院外心脏骤停，但这些潜在的救援人员在传统班级中的代表性不足。我们对 40-70 岁人群的 VSI 项目进行了评估，该项目包括 22 分钟的视频、充气训练模型和音频提示设备。假设 VSI 使基本 CPR 技能的表现优于未经培训的学习者，并与 Heartsaver 课程中的学习者相似。 方法：285 名 40 至 70 岁之间、在过去 5 年内没有接受过 CPR 培训的成年人被分配到未经培训的对照组、Heartsaver 培训组或 VSI 的三个版本之一。基本心肺复苏技能通过教练评估和传感模型进行测量。结果：VSI 组中评估无反应、拨打紧急电话号码 911、提供足够通气、正确放置手部和足够按压深度的受试者百分比明显优于未经训练的对照组 (P < 0.05)。 VSI 受试者往往比 Heartsaver 受试者具有更好的整体表现和更好的通气性能。结论。通过这个培训项目，老年人在大约半小时内学会了心肺复苏的基本技能。如果分配得当，这种类型的培训可以显着增加能够进行心肺复苏的非专业急救人员的数量。 (c) 2005 Elsevier Ireland Ltd. 保留所有权利。
Background: The length of current 4-h classes in cardiopulmonary resuscitation (CPR) is a barrier to widespread dissemination of CPR training. The effectiveness of video-based self-instruction (VSI) has been demonstrated in several studies; however, the effectiveness of this method with older adults is not certain. Although older adults are most likely to witness out-of-hospital cardiac arrests, these potential rescuers are underrepresented in traditional classes. We evaluated a VSI program that comprised a 22-min video, an inflatable training manikin, and an audio prompting device with individuals 40-70 years old. The hypotheses were that VSI results in performance of basic CPR skills superior to that of untrained learners and similar to that of learners in Heartsaver classes.Methods: Two hundred and eighty-five adults between 40 and 70 years old who had had no CPR training within the past 5 years were assigned to an untrained control group, Heartsaver training, or one of three versions of VSI. Basic CPR skills were measured by instructor assessment and by a sensored manikin.Results: The percentage of subjects who assessed unresponsiveness, called the emergency telephone number 911, provided adequate ventilation, proper hand placement, and adequate compression depth was significantly better (P < 0.05) for the VSI groups than for untrained controls. VSI subjects tended to have better overall performance and better ventilation performance than did Heartsaver subjects.Conclusions. Older adults learned the fundamental skills of CPR with this training program in about half an hour. If properly distributed, this type of training could produce a significant increase in the number of lay responders who can perform CPR. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
