The conductivity of dialysis fluid. Dialysis fluid consists of a solution of inorganic salts that are dissociated in electrically charged ions. These ions can move in an electric field giving the salt solution electrically conducting properties, called conductivity.
Accordingly, why do we check conductivity in dialysis?
The conductivity setting of the dialysis machine directly corresponds to the level of sodium in the dialysate. A higher conductivity means a higher sodium level in the dialysate and vice versa. By altering the conductivity desired, we can tell the machine what sodium level we would like the blood to be exposed to.
Keeping this in consideration, what is the acceptable range for dialysate conductivity?
12-16 mS/cm
Extracellular Volume Control (Ultrafiltration) The major driving force that determines the rate of ultrafiltration or convective flow is the difference in hydrostatic pressure between the blood compartment and the dialysate compartments across the dialysis membrane; this is called the transmembrane pressure (TMP).
