Dialysis recirculation test
WebDecreases in delivered dialysis dose: May be indicative of either insufficient blood flow or high recirculation possibly due to stenosis Excessive negative pressures (below -200 mm Hg with 15-gauge needles and a blood flow of 400ml/min): May indicate a failure of the fistula to provide the flow demanded by the blood pump due to a potential ... WebJun 8, 2024 · A numerical investigation of flow topology in open-type cavities with length-to-depth ratio L/h1 = 4 was performed in the Reynolds number range of 10–1000. Cavities with differently rounded corners were chosen for simulation. Three-dimensional numerical simulations were performed to analyse flow topology in different planes. A …
