MSRA-0171

You have just received a 70-year-old man into the resuscitation room who had a witnessed collapse after complaining of chest pain. There was no pulse, and cardiopulmonary resuscitation (CPR) was performed at the scene. CPR is ongoing upon patient arrival in the Emergency Department. Pulse check demonstrates no palpable central pulse, and there is no respiratory effort. A 3-lead electrocardiogram (ECG) demonstrates no coordinated electrical activity or recognisable complexes, looking very much like a wandering flat line.
What is the most appropriate management of this patient?
