I don't agree with the term "1 to 1". Patients should be looked at on an individual basis, as to their acuity, not solely on the amount of equipment in the room. The baloon pump is another piece of equipment requiring assessment as is a ventilator or a swan ganz catheter. I've cared for patients that didn't have balloon pumps that required more vigilence than some balloon pump patients I've cared for. The real point of this discussion should be maintaining safe staffing levels for ALL patients. I think it can be a safe situation to have a balloon pump patient with another patient when acuities are taken in to account and assignments made accordingly.
