Intent: Evaluate eArrest.18, eArrest.17, and eArrest.12 to obtain higher certainty of perfusion status on arrival at destination.
First Check eArrest.18 (End of EMS Cardiac Arrest Event)
Next, Check eArrest.17 (Cardiac Rhythm on Arrival at Destination)
If Sustained ROSC has not yet been set because neither of the above is true, check combinations in eArrest.12 (Any Return of Spontaneous Circulation) for Sustained ROSC
