I started in CVICU, took my first open heart at 6 months and have never regretted my decision to begin in critical care. I learned in one year what it took my nursing school peers to learn in 3 years or maybe still haven't had the opportunity to learn. I'm a firm believer that once you have critical care skills, you can work anywhere. I also think you cannot assume that having one or two patients in critical care is easy, there is so much more critical thinking that is required. You have to know what to do at a moments notice, you have to use your judgement constantly to keep the patient safe. You generally do not have any other help like a CNA or techs, ICUs are usually always total care (bathing, meds, turning, cleaning after stooling, vitals, etc). In the years I have been a critical care nurse, I really don't remember sitting down too much, even with my 1:1 hearts, IABPs, CRRT, etc. If you are committed to learn, committed to a lifetime of constant learning and education, then go to critical care, if not, then it may not be the best fit.
