As Jennie said, it depends on the size and the acuity of the CCU. After spending a year or so in a CCU, I transferred to CVICU because people that come out of CABG, MVR, etc must go to a unit.......they are all vented, most have swans and numerous drips. Alot of CCU patients might need ICU, but they are awake, talking, etc. I learned more about hemodynamics during my CVICU orientation than I did the entire time in the CCU, simply becuase I was shooting outputs and manipulating gtts/blood products/whatever around those values to stabilize the patient. When they are stable and off the vent, they move to step down and you get fresh, acute patients to work with again. We are just getting into CV lectures, so I hope that experience will serve me well.
