ABSTRACT
INTRODUCTION:
Basic life support (BLS) and the use of an automated external defibrillator (AED) improve survival from cardiac arrest. The gold standard for teaching BLS/AED is yet to be identified. The aim of this study was to compare the learning outcome of an instructor-led demonstration with a formal lecture for introducing BLS/AED skills. We hypothesized that a demonstration was superior to a lecture.METHODS:
First year-medical students were randomised to either a demonstration or a lecture using PowerPoint® Presentation for skill introduction during European Resuscitation Council BLS/AED courses. Participants were skill-tested after training and required to perform all skills correctly to pass the test. Finally, all participants were asked to state their preferred teaching method.RESULTS:
Overall, 247 participants were included in the analysis (demonstration group 124, lecture group 123). Pass rate was 63% in both groups, pâ¯=â¯1.00. Both groups performed median compression rates within guidelines recommendations, pâ¯=â¯0.09. Mean compression depth was 55â¯mm (10â¯mm) in the demonstration group compared with 52â¯mm (10â¯mm) in the lecture group, pâ¯=â¯0.05. Median tidal volume was 265 (192, 447) ml and 405 (262, 578) ml, pâ¯<â¯0.001, respectively. The lecture group was 3â¯s faster at initiating BLS, pâ¯<â¯0.001. In total, 226 (91%) participants preferred demonstration on a manikin for introducing BLS/AED.CONCLUSION:
There was no statistically significant difference in pass rate when comparing a demonstration with a lecture for introducing BLS/AED. The lecture group was slightly faster at initiating BLS. Most participants preferred a demonstration as introduction.Key words
