Dialysis Machine Conductivity Range – Technical Standards & Clinical Safety

What Is Conductivity in Dialysis?
Conductivity in dialysis refers to the ability of the dialysate solution to conduct electricity, which is directly related to the concentration of electrolytes (mainly sodium and chloride) in the dialysate. Proper conductivity ensures safe and effective fluid and solute exchange during hemodialysis.
 

Normal Conductivity Range

Parameter	Standard Range
Conductivity Value	12.5 to 15.5 mS/cm
Typical Set Point	13.5 to 14.0 mS/cm
Alert/Alarm Limits	±0.5 mS/cm from target

Note: Values may vary slightly depending on the machine model and local treatment protocols.

Regulatory Compliance
ISO 23500-4 and IEC 60601-2-16 define safe conductivity ranges

Dialysis machines are typically factory-calibrated and verified daily by clinical staff
