Unilateral dilated pupil and spontaneous cardiac arrest with successful bystander resuscitation

Hancox JM, Spiers J, Crombie N, Naumann DN. Case Reports in Emergency Medicine. 2017;2017:3.

A 75-year-old man collapsed on a golf course and received cardiopulmonary resuscitation from a bystander, including the use of a public automated external defibrillator (AED). The AED was discharged once, with return of spontaneous circulation. 

This case illustrates the utility of early deployment of an AED as well as the importance of an accurate history and emergency decision-making by pre-hospital personnel.
