Abstract 85: The Effectiveness of a Short Course in CPR and AED Usage for Lay Persons
The objective of this study is to compare the effectiveness of a 30 minute, video-based course in CPR-AED to the standard 2.5 hour adult CPR-AED course being provided for lay persons.
Methods: One hundred volunteers (over 18 years old) were randomly assigned to one of the three study groups. (Group A) 30 participants received the traditional 150-minute adult CPR-AED course. (Group B) 35 participants received the video-based 30-minute CPR course. CPR skills were learned by watching the DVD practicing independently using a personal CPR training manikin in a practice-while-watching format. AED use was learned during an additional 20-minute practice period with a supplemental tool (simulated AED, AED pads, and patient poster) supplied to each participant. (Group C). 35 participants received the same CPR course as used for Group B. AED instruction was provided only by 10-minute DVD (no physical hands-on AED training). All subjects were given a practical exam at the conclusion of the course. The evaluators had not participated in the instructional component of the course. A standardized evaluation scale were used to grade the performance of 9 critical elements of CPR and 6 critical elements of AED. All AED trainers were programmed for the Japanese guidelines, 1-shock protocol.
Results: The CPR evaluations of Group B & C were almost equal to that of Group A. Exceptions were: Group A was better that B and C in checking breathing. Group C was worse than A at clearing the patients before analysis and before shock, and resuming compressions immediately after analysis/shock. Group B was almost equal to Group A, except for clearing the patients before analysis.
