Dialyzer Kuf

Ultrafiltration Form

High flux dialyzers have a coefficient of ultrafiltration (Kuf) of >15-20ml/h/mmHg. Kuf reflects the ‘leakiness’ of the membrane to water. Dialyzers with a high Kuf need less TMP to achieve the same rate of ultrafiltration. Small changes in TMP in a high flux dialyzer can cause dramatic fluid shifts and ultrafiltration. Therefore, precise volumetric control of UF is required with modern day, high flux dialyzers.
