Bystander cardiopulmonary resuscitation (CPR) improves survival from out-of-hospital cardiac arrest (OHCA) but often is not performed. We hypothesized that subjects viewing very short Hands-Only CPR videos will (1) be more likely to attempt CPR in a simulated OHCA scenario and (2) demonstrate better CPR skills than untrained individuals.
This study is a prospective trial of 336 adults without recent CPR training randomized into 4 groups: (1) control (no training) (n=51); (2) 60-second video training (n=95); (3) 5-minute video training (n=99); and (4) 8-minute video training, including manikin practice (n=91). All subjects were tested for their ability to perform CPR during an adult OHCA scenario using a CPR-sensing manikin and Laerdal PC SkillReporting software. One half of the trained subjects were randomly assigned to testing immediately and the other half after a 2-month delay. Twelve (23.5%) controls did not even attempt CPR, which was true of only 2 subjects (0.7%; P=0.01) from any of the experimental groups. All experimental groups had significantly higher average compression rates (closer to the recommended 100/min) than the control group (P<0.001), and all experimental groups had significantly greater average compression depth (>38 mm) than the control group (P<0.0001).
Laypersons exposed to very short Hands-Only CPR videos are more likely to attempt CPR and show superior CPR skills than untrained laypersons. Clinical Trial Registration- URL: http://www.clinicaltrials.gov. Unique identifier: NCT01191736.
旁观者心肺复苏术（CPR）可提高院外心脏骤停（OHCA）患者的生存率，但往往未得到实施。我们推测，观看极短的仅胸外按压心肺复苏视频的受试者将：（1）在模拟的院外心脏骤停场景中更有可能尝试进行心肺复苏；（2）与未受过训练的个体相比，表现出更好的心肺复苏技能。
本研究是一项前瞻性试验，将336名近期未接受心肺复苏培训的成年人随机分为4组：（1）对照组（无培训）（n = 51）；（2）60秒视频培训组（n = 95）；（3）5分钟视频培训组（n = 99）；（4）8分钟视频培训组，包括使用人体模型练习（n = 91）。所有受试者均使用可感应心肺复苏的人体模型和Laerdal PC技能报告软件，在成人院外心脏骤停场景中测试其进行心肺复苏的能力。一半接受培训的受试者被随机分配立即进行测试，另一半在延迟2个月后进行测试。12名（23.5%）对照组受试者甚至未尝试进行心肺复苏，而任何一个实验组中只有2名受试者（0.7%；P = 0.01）未尝试。所有实验组的平均按压频率（更接近推荐的100次/分钟）均显著高于对照组（P < 0.001），且所有实验组的平均按压深度（> 38毫米）均显著大于对照组（P < 0.0001）。
观看极短的仅胸外按压心肺复苏视频的非专业人员比未受过训练的非专业人员更有可能尝试进行心肺复苏，并表现出更出色的心肺复苏技能。临床试验注册 - 网址：http://www.clinicaltrials.gov。唯一标识符：NCT01191736。
