You are dispatched to a local restaurant for 27-year-old male who is unconscious. En route to the scene, dispatch gives you an update that the patient is in cardiac arrest At the time of EMS arrival, the patient is found supine on the floor in cardiopulmonary arrest.

Effective chest compressions are being performed by a nurse who had been having dinner with her husband. The patient is a server at the restaurant. His co-workers report that the collapse was witnessed and the patient had been behaving "normally" prior to the event. They are unaware of any significant medical history. The cardiac monitor is attached.

Paramedics deliver a shock at 150 J.
