Yes, improved survivability if ROSC within a certain time frame, 1.5 hrs?
Depends on your area and protocols. Study's have shown improvement in survivability and neuro out come of obtaining ROSC in the field prior to transport. Field terminations are becoming more common in EMS on medical arrests. Mainly in part you're unable to properly work an arrest in a moving ambulance.Requirements in my area for field term are 30 minutes of basic ACLS. Epi, fluids, ET/ laryngeal airway, bicarb/ calcium on renal pts. If the patient remains in asystole med controls is contacted for any additional orders, with no change we terminate.
