What is the normal dialysate conductivity range?

• A. 10.0-12.0
• B. 15.0-18.0
• C. 12.6-15.9
• D. 20.0-25.0

Answer: (C)

Dialysate conductivity reflects its total ion content and helps ensure safe electrolyte balance during dialysis. The normal range is about 12.6 to 15.9 mS/cm, which matches the conductivity of blood plasma and supports proper diffusion of electrolytes without causing sudden shifts. Keeping within this window minimizes the risk of unintended electrolyte gains or losses as wastes move across the dialyzer membrane. If conductivity is below this window, the dialysate is less ion-rich and can promote unwanted diffusion of electrolytes from blood; if it’s above the window, excess ions can diffuse into the blood, raising the risk of disturbances like hypernatremia. Machines monitor conductivity and alarm if it drifts outside the target range.
