| Learning Objective #2: compare effectiveness of CPR when training is delivered via self-managed video, facilitator-managed video,and traditional classroom instruction. |
Because neurologically intact survival is of utmost priority following cardiopulmonary resuscitation (CPR), all rescuers must provide adequate number and depth of chest compressions with minimal interruption from ventilations. In an effort to maximize coronary and cerebral perfusion, the 2005 American Heart Association (AHA) Guidelines for CPR simplified compression: ventilation ratios across the lifespan to 30: 2. Research has shown that laypersons enrolled in traditional 4-hour CPR classes are failing to master skills or retain content. The literature suggests that alternative instructional modalities (self-managed and facilitator-managed) promote CPR skill efficacy when compared with traditional 4-hour CPR training. In this study, CPR knowledge and skill performances were evaluated among laypersons over the age of 18 years who learned CPR for the first time via self-managed video (n = 84), facilitator-managed video (n = 45), and traditional class (n = 72). All learning occurred in a controlled environment, with both learning and skill performances videotaped. CPR performance was evaluated by an observer using the AHA skills checklist and by sensored manikins equipped with Laerdal Heartsaver computer software. There were no significant differences in number of adequate compressions or duty cycle with self-managed video and traditional classes. Those who learned via self-managed video had significantly fewer adequate ventilations than did those who learned via traditional method. Those who learned via facilitator-managed video consistently underperformed those who learned with self-managed video or traditional instruction. While the search continues for a course that results in high-level CPR performance, this study indicates that compared to traditional courses, self-managed video learning is a viable approach to CPR education. Self-managed video has the added benefits of being more accessible and time efficient (about 25 minutes).
