Objective: Basic life support (BLS) is a very important application that any rescuer from the public can easily implement with short training, and thereby, that can save the lives of thousands of sudden cardiac arrest cases. In this study, the aim was to the determine information level of current basic life support of candidate teachers and to evaluate the educational activities that are carried out in order to improve these levels. Methods: A total of 213 volunteer students from Ahi Evran University Faculty of Education was included in the study. With 20 multiple-choice test questions, basic life support knowledge levels of the candidate teachers were determined and upon this evaluation, 2 hours of face-to-face applied training was offered. In order to evaluate the persistence of the knowledge level of these students, the same test has been re-applied one month and six months later. Results: According to the result of the pre-test, the knowledge levels of the student groups were low. A month later, their level of knowledge increased from 41.65% to 79% and Six months later, there was a 2.32% decrease in their level of knowledge. Conclusion: In this study, it has been shown that the two-hour basic life support training given to the candidate teachers is beneficial and increases their courage in this regard. Therefore, we believe that regular basic life support training provided to candidate teachers may prove effective in the increase of the intervention rates to out-of-hospital cardiac arrest cases.
