We sought to determine if, in patients with out-of-hospital cardiac arrest (OHCA), the description of any specific symptoms to the emergency medical dispatcher (EMD) improved the accuracy of the diagnosis of cardiac arrest. ⋯ Dispatchers should recognize cardiac arrest when a victim is described as unconscious and not breathing or not breathing normally, and consider cardiac arrest when generalized seizure is described. They should receive specific instructions on how to best recognize the presence of abnormal breathing.

Randomized Controlled Trial Comparative Study
Effect of a reminder video using a mobile phone on the retention of CPR and AED skills in lay responders.
Skills related to cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use by lay responders decay rapidly after training, and efforts are required to maintain competence among trainees. We examined whether repeated viewing of a reminder video on a mobile phone would be an effective means of maintaining CPR and AED skills in lay responders. ⋯ Repeated viewing of a reminder video clip on a mobile phone increases retention of CPR and AED skills in lay responders.

Early bystander cardiopulmonary resuscitation (CPR) provides an essential bridge to successful defibrillation from sudden cardiac arrest (SCA) and there is a need to increase the prevalence and quality of bystander CPR. Emergency medical dispatchers can give CPR instructions to a bystander calling for an ambulance enabling even an inexperienced bystander to start CPR. The impact of these instructions has not been evaluated. ⋯ There is limited evidence supporting the survival benefit of dispatch-assisted CPR instructions. All studies comparing survival outcomes when CPR is provided with or without the assistance of dispatch-assisted CPR instructions lack the statistical power to draw significant conclusions. Since it has been demonstrated that such instructions can improve bystander CPR rates, it is reasonable to recommend they should be provided to all callers reporting a victim in cardiac arrest.
