Definitions of Terms
Kt/V The Kt/V is the dialysis dose of the dialysis treatment in progress.
The quality of the Kt/V information content depends on the accuracy of
the individual parameters, i.e. primarily on the accuracy of the volume
of urea distribution V that was entered. The accuracy of V is the
responsibility of the attending physician.
If no valid value for V is available (neither entered directly nor calculated
from the patient data), Kt instead of Kt/V will be calculated and
displayed.
Interval Time between two measuring cycles
Hct Percentage of the volume of the red blood cells in the total blood.
Clearance The clearance (K) (in ml/min) is the average effective urea clearance.
which describes the blood flow volume that is completely cleared of
urea.
Caution
The treatment parameters may not be determined on the basis of the
measured parameters (Clearance, Kt/V, Plasma Na).
A measurement of the clearance and the plasma Na does not replace
the therapy prescribed by the physician.
K = Blood flow completely cleared of urea per unit of time (Clearance)
t = effective dialysis time
V = volume of distribution of urea
