From AANA:
The requirements for becoming a Certified Registered Nurse Anesthetist (CRNA) mainly include having a bachelor's degree in nursing, Registered Nurse licensure, a minimum of 1 year acute care experience (ICU, ER for example)....
Education of Nurse Anesthetists in the U.S.
Not possible to do "his 1 year in the ICU while in the first year of CRNA school" as requirement of 1 year expeerience in acute care needs to be completed
prior to starting nurse anesthesia program.
Some programs may conditionally accept a student based on application package to enter a program at future date upon completion of 1 year acute experience. A Program would loose accreditation if 1yr minimum not upheld.
There is a whole world of nursing out there that one is just becoming aware of/exposed to with one years experience. Use that time wisely as it is an Advanced Practice role. Need the seasoning of a few years of practice/ clinical experiences to really perform well ahead of the newbie learning curve.
