4.7.1.12 Dialyser Parameters (Kt/V)
1. Activate the System Configuration menu with
the System Configuration key in menu
Treatment Support. Use the scroll bar until the
following menu appears.
2. Activate the Dialyser Parameters (Kt/V) menu
with the Dialyser icon.
The following parameters can be set.
• Default Target Kt/V
• Urea Distribution Volume Formula
• Height Measurement Unit of Watson Formula
• Default Setting for Treatment Mode:
Warning of Kt/V Target Projected Deviation
• Kt/V Table - Manual INPUT:
Setting Clean Blood Volume [%] Enabled
• Warning for Saving Kt/V Table
• Dialyser Filter Urea Clearance Data
If Nexadia-BSL is selected
Only the first parameter point Default Target Kt/V is displayed, but Kt/V is still
active in Nexadia-BSL.
If WAN-BSL is selected
No display, Kt/V is not active in WAN-BSL, i.e. empty screen.
Default Target Kt/V
The target value is the Kt/V value at the end of a therapy. The target is set by
the user.
Urea Distribution Volume Formula
Kt/V can be calculated with one of two different equations.
Urea Distribution Volume Formula (Basic)
The calculation is according to the following equation:
V (litres) = 0.58 x Dry Weight (kg)
Urea Distribution Volume Formula (Watson)
The calculation is according to the following Watson equation:
Male:
V (litres)=2.447 – 0.09516 x Age (years) + 0.1074 x Height (cm or feet/inch) +
0.3362 x Dry Weight (kg)
Female:
V (litres)=-2.097 + 0.1069 x Height (cm or feet/inch) + 0.2466 x Dry Weight
(kg)
