To establish the effectiveness of different methods of early AED application (non-dispatched layperson, dispatched layperson, dispatched professional, drone delivery - all interventions) versus standard care (comparator) in adults who suffer a witnessed out-of-hospital cardiac arrest in a public setting (population) upon outcomes of survival and neurological function.
