I worked in an ICU after school was done. I did that for almost 3 years. At that time I had been working in EMS for about 7 ears and the ER seemed a better fit for me. I now work in the ER and have been for about 1.5 years. I love every minute of it. Lots of variety and you still use your brain. I found the ICU to be the same thing everyday(vents,swans,pacemakers) The patients rarely talked back. I get the same experience in the ER (except swans)and i have other patients who get better quicker and actually go home.:) Depending on your personality, if you are a creature of change...the ER is for you. (i sound like a saleman) good luck with your choices. You can always move if you are unhappy. We also have an ICU float pool that floats from ICU and ER. Maybe that is for you.
