Also DaveS I would like to share something with you technically CRNAs are not suppose to do hearts or real big cases WHY! my understanding 1.AA Is consider MEDICINE("hard") science at a medical school environment which the teachers are Board Certified Anesthesiologist MDAs,PhDs,& Medical Director as well, who teach the course. 2.CRNA Is consider NURSING(advance)at a nursing school environment which the teachers are MSN,DON,orPhD in nursing. So Why are you doing hearts or big cases if your not suppose to do those type of cases?..just curious.
