Discussion
Findings of the study showed that basic life support skill significantly increased due to the application of both real-time feedback training and Debriefing by Video Recording methods, while there was no significant difference between the two training methods.Regarding the effect of real-time feedback method, our study findings were in line with the findings of Tanaka et al. study, which examined the effect of real-time auditory feedback device on the skill of non-professionals trained in Japan. Their results showed that the use of feedback devices in cardiopulmonary resuscitation has been able to significantly improve quality of CPR [Based on the findings of the present study, in both groups, the evaluation factors by CPRmeter 2 feedback device increased significantly after the intervention, but the rate of increase of these criteria was higher in the real-time feedback group than Debriefing by Video Recording group in the post-test. Intergroup comparison of real-time feedback method compared to Debriefing by Video Recording method in chest compression depth parameters (
