              Reproducible benchtop studies were conducted using expired, human-banked blood in simulated cardiopulmonary bypass and organ-procurement circuits, comparing Nephros directly against conventional management. The protocol measured not only speed of correction but the full physiologic impact of each approach across electrolyte, acid-base, and volume parameters.
