Association between bystander intervention and emergency medical services and the return of spontaneous circulation in out-of-hospital cardiac arrests occurring at a train station in the Tokyo metropolitan area: A retrospective cohort study

Effects of changes in the volume of automated external defibrillator audio guidance on audibility: a pilot usability study

“…Thus, the audibility of the AED audio guidance is a very important feature. In recent years, OHCA in public places has been reported to be associated with favorable outcomes [6,[10][11][12]. It is hoped that the widespread implementation of AEDs, featuring both easy-to-hear audio guidance and highly visible visual guidance, will enable everyone to use an AED safely and effectively, even during emergencies.…”

“…Public places, for example, tend to be noisier than residential areas, increasing the likelihood that the user may not hear the AED's audio instructions and may operate the device incorrectly. Despite these challenges, OHCA occurrences in public places are expected to have favorable outcomes [6,[10][11][12]. Therefore, reliable and rapid defibrillation is crucial.…”
