What does an ICU nurse do exactly?

  1. 1
    Can you please tell me what the regular routine or functions or duties of ICU nurses?

    Is there a lot of cleaning after patients? Or is it more in the technical and mechanical field of nursing?

    I work in a CCU. Though CC nurses usually have 1-2 patients, Critical Care Nurses have many functions. Critical thinking is a big one.We look at the entire picture and how everything relates to plan for the best outcome for the patient. We look and intrepret labs and determine whether the dr needs to be called for abnormal values and we take steps to correct the values. If a patients condition is deteiorating we look at the big picture to figure out what is going on and support the patient until problem can be solved. We can order ABGs, CXRs, Labs, etc to try and pinpoint problems based on what we see. Often there are standing orders that we have that can be used based on clinical intrepretation to guide our care (ie: to start vasoactive meds, for pain control, to give blood products, for codes, for extubation procedures, etc). We use technology to assist us in our care (vents, swans, icps, and many other things), We titirate medications that are very potent to manage clinical symptoms and "numbers" obtained from our technology. If the patient is actively trying to die, we take measures to save them the best that we can. On top of all that, we do basic care for the patient, keep them as comfortable as we can, take care of their emotional and spiritual needs and we support the family (which can be a big job in itself, LOL). We are the patient's advocate. We are the ones talking to the families to find out the needs of the patient (if the patient is unable to speak for themselves). We coordinate the patient/family wishes with the plan of care and to the doctor. Many ICUs do not have CNAs, if your patient is vomiting or has frequent BMs, is "crazy" etc, it us up to you to do the cleaning, turning, skin care, baths, feeding, etc. It is a great job, both technical/mechanical but the "basics" are just as important to remember! I am sure that others will have more answers as to what an ICU RN does.

    zambezi said it very well. It is, yes, very technical. It is also very messy and you are usually the one who cleans up. There is better staffing (usually!) in that there are more RNs. Frequently there is no aide. Rarely are you alone, though; most units function with a great deal of teamwork so when you have a huge "code brown," your fellow nurses generally attend your poop party with you.

    We usually have 1 tech to 13 beds, so yes, it gets messy. And there are jobs such as suctioning that get really messy and we don't delegate it to anyone.

    Zambezi wrote a very good summary of what critical care is.

    Essentially like other areas of nursing you do and are responsible for evrything

    ICu nursing is a roller coaster ride. you never know what is around the corner, both physically and emotionally. it is different to ward nursing, in the view that i go home every day knowing that i gave the patient ALL the care they required. yet on the wards, you'd be lucky to find the time to say hello to some of them. In the 6 years i've worked in ITU, i have learnt and experienced so much; it scares me to think of the lack of knowledge in certain areas of nursing, that i had when i worked on the wards!!!

    I have worked as an ICU nurse for over 35 years and would never want to do anything else. I started out on a med/surg unit where I worked for over 10 years and often found myself having as many as 13 or 14 patients (that was back in the 60s during team nursing....which they are bringing back and calling manager care). I felt that I needed a change and transfered to ICU. Its a different kind of busy than a floor nurse. I find its easier to be organized in ICU. I never have more than 3 patients and its rare to have three. If patients are on 1:3 care we try to get them up to the floor. Usually I have two patients and occasionally I will only have one very critical patient (1:1) or assist an RN with a 2:1 care--usually a fresh post op open heart or just patients who are crashing in general. I much prefer this to my 14 patients of yesteryear. What is more challenging however is that you have to be much more quick on your feet and make quick decisions and things can change so quickly. Its not for everyone as our turnover is pretty high. However, I think it would be a good experience for every nurse to spend just six months working in a critical care setting....you truly get to use all your skills and technology is always changing and there iare constantly new things to learn.

    Zambezi, GREAT description!

    Intensive care nursing is an opportunity to work with pt's and families when they are at their most vulenerable. It is an honor and very humbling to be an ICU nurse. It is an exciting, adrenalin filled, awesome experience one day, depressing and frustrating the next. It can make you cynical and change your sense of humor, it definitly changes your outlook on life and how you live it! There is no other job like it.

    I agree with the other posts, you have to be organized and have good critical thinking skills. If you get the chance to "shadow" an ICU nurse for a while, do it! You also have to look at the ICU itself. Different hospitals have different acuties of ICU patients. Some ICU's don't do as much or any of all the invasive, highly technological stuff that other ICU's do. So that's another thing to consider.

    Zambezi summed it up sooo well! I like jobs that are physically mentally and intellectually stimulating... ICU nursing does just that! mactempest.

    The best points of ICU nursing have been pointed out, but I need to make one more. Don't ever let anyone tell you, or think yourself, "How hard could taking care of 2 patients be?" I started on a busy med surg floor, and that is what I heard alot. Well let me tell you, I have been in the unit for over a year, and I am busier most times then I was on the floor! When you have a vented patient with all the drips, tube feeds, cdiff, ect, I run by butt off all day! So, get any notion out of your head two paitents would be a breeze, because it isn't! LOL
