Understanding Dialysis Machine Conductivity

Dialysis machine conductivity refers to the measurement of the electrolyte concentration in the dialysate. This parameter is crucial because it ensures that the fluid used for dialysis matches the prescribed sodium and ion balance for the patient.

Why It Matters:
Patient Safety – Incorrect conductivity can cause severe shifts in blood sodium levels, leading to cramps, hypotension, or cardiac issues.

Treatment Accuracy – Ensures proper osmotic gradient for effective toxin removal.

Machine Function – Serves as a real-time quality check for the dialysate mixing system.

How It Works:
The machine uses electrical conductivity sensors to detect ion levels.

Typical conductivity range: 12–16 mS/cm (varies by prescription).

Monitored continuously during treatment, with alarms if values deviate.

Troubleshooting:
Low Conductivity – May indicate insufficient concentrate or water quality issues.

High Conductivity – Could mean over-concentration or mixing malfunction.

Sensor Calibration – Regular maintenance prevents measurement errors.

Maintaining correct conductivity is essential for safe and effective hemodialysis.
