The effect of video-instructed versus audio-instructed dispatcher-assisted cardiopulmonary resuscitation on patient outcomes following out of hospital cardiac arrest in Seoul

Abstract We aimed to investigate whether video-instructed dispatcher-assisted (DA)-cardiopulmonary resuscitation (CPR) improved neurologic recovery and survival discharge compared audio-instructed DA-CPR in adult out-of-hospital cardiac arrest (OHCA) patients a metropolitan city with sufficient experience facilities. A retrospective cohort study was conducted for bystander-witnessed OHCA administered due presumed etiology between January 1, 2018 October 31, 2019 Seoul, Korea. The primary secondary outcomes were the differences favorable outcome rates two instruction groups. Binary logistic regression analysis performed identify predictors after DA-CPR. total of 2109 enrolled. Numbers elderly audio video 1260 (73.2%) 214 (55.3%), respectively.
