Whynotme,
I am cursious to where you are in your degree, are you currently attending nursing school? Usually Nurse anethesists obtain their RN/BSN(4yr) first. Then, they will apply to the Nurse Anethesist program(2yr). After completing the two program they will undergo a internship/residency (may be different per state). Then, you would need to take your license exam.
Nurse anethesists work with the anesthesiologists but are more independent than usually thought. The nurse anethesists typically will run the patient status during the surgury with the anesthesiologist occasionally popping in to check on the progress.
Now, salary. Nurse Anethesists are paid very well and you will be able to pay off your loans and live comfortable.
The future for nurse anethesists is very bright. Due to certain issue happening in capital hill it may be that nurse anethesists are completely independant. Meaning there is the potential Anesthesiologists may fade. Hopefully they don't but it may happen.
