In the companion document under the medical cardiac arrest directive it lists reasons for early transport. Under here it lists thrombosis (pulmonary and coronary). So to my understanding, if we have a VSA we believe to be caused by a coronary thrombosis (a STEMI) we are to do 1 analyze? In the past it has been said that we are to treat a suspected MI VSA as a medical cardiac arrest and run the entire protocol on scene. Can you please clarify?
