In our CCU/CVICU if we float a nurse to an other unit, before we do that we will call and see if some one who is not working will take call for $2.00 an hour. This way the nurse does not get pulled back to the unit and the floor is not put in a bind. If an CCU patient comes in we call the in the call nurse.
By the way our ICU, CCU only takes 3 patients and the CVICU only takes one patient if within 18 hours and only 2 patients if greater than 18 hours post op, or what clinical situation allows.
