Mr. Dean:

Great questions and topic.  In the system I work in we do not have a set in stone policy of routine versus emergency transports of patients but we do have some guidance in our protocols.  We must find a way to include this yet still allow for the interpretation of the patient's condition by the EMS crew.  As for working a cardiac arrest, it has been my experience that most staff would work on the scene.   Personally I like to try and work a little on the scene and then transport.  This allows for more efficient intubation and IV success (plus efficient CPR) but then also provides for quicker transport to other medical providers who can provide additional care.  I hope we continue to proceed to discuss more advanced topics like this and get away from the old Ambulance Driver mentality.

Thanks!
