Fluid Balance

I’m a bit confused on what is going on with my fluid balance. I thought that I was losing weight but retaining fluids so my weight is fairly constant. Once we started removing more fluid during dialysis, my weight should drop more. My nephrologist thinks there a couple of liters of excess fluid by looking at my lower legs. After a week of using the Crit-Line monitor, my lower legs look pretty “normal” but my weight haven’t changed that much. My scale at home says I’m about 81.0 kg now, which is pretty consistent over the past several weeks.

From what the nurse showed me, there’s several “buckets” of fluid: in cells, between cells, and in the bloodstream. I found this chart online:

I’m not sure what my percentages are but we’re trying to remove more fluid than what is moving to the first area or blood plasma. I was told that during dialysis, as we remove fluid, it’s constantly being replaced by fluid in and between cells. It seems to make a difference how fast fluid is removed during dialysis, though I can’t understand why. Here is the Crit-Line graph from Thursday:

Initially, nothing much was happening. After an hour, the chart started to show a decrease in blood volume % change. It seems the flow rate between the different fluid buckets in the body is not constant either. Even though we didn’t change the setting after the marker, the chart values change constantly. Blood pressure is much improved as well, which supports the conclusion that fluid in the bloodstream is lower than before when my blood pressure was up to 180’s. I didn’t caputre Saturday’s chart but the blue wedge was much larger as we removed 3,200 mL of fluid and I ended at 78.4 kg. The only questions is what is different since my weight is about the same. Either I gained non-fluid weight (unlikely) or fluid is being retained in the cells but the absence of edema says otherwise. Very confusing.
