Abstract
Background: There are a limited number of automated external defibrillator (AED) trainers for basic life support (BLS) training in Thailand. These devices are costly and have to be imported. We developed a Chiang Mai AED trainer to reduce the cost burden of BLS training. The goal of this study was to investigate the effectiveness of Chiang Mai AED trainer.
Methods: This was a descriptive study of our newly developed Chiang Mai AED trainer. The prototype was examined by 5 BLS instructors including 2 Cardiologists, 1 Anesthesiologist, and 2 Emergency Physicians. We used a questionnaire to evaluate the device’s efficacy and its similarity to an actual AED. Correlation among instructors was also calculated.
Result: Chiang Mai AED trainer prototype was effective for use in BLS training according to all BLS instructors. The device was able to show the accuracy of electrode pads placement, and instructors were able to skip steps with the controller. Kappa correlation coefficient of the AED trainer was 0.94. Evaluation of the similarity to an actual AED with a visual analog scale resulted in a median of 45 (Interquartile range 43, 47) out of 50. Intraclass correlation was 0.92 (95% CI 0.72-0.99, p < 0.001)
Conclusion: Chiang Mai AED trainer prototype is effective to use for BLS training.
