I have also had a welcome like yours many times in ICU. From the moment the machine approaches the room, it's the dialysis nurse's fault if the patient crashes. I originally worked one hospital, so I developed a relationship with the ICU staff over time, but that is not likely to happen if you travel and aren't often in the same site. I would think the staff would be glad to have someone in the room, but often that is not the case. Linda Bethea
