2008T Hemodialysis Machine with CLiC Device User’s Guide P/N 490206 Rev E 15
The BV (Blood Volume) graph
Note : The BV graph is the default upper graph displayed on the
“Crit-Line” screen. To display the Hct graph instead of the BV
graph, call a qualified service technician.
The BV (Blood Volume) graph is displayed as a fill graph. A line is filled
from 0 to the
Δ BV% value. As the dialysis treatment progresses, fluid is
taken out of the blood by the 2008T hemodialysis machine’s ultrafiltration
pump. This will result in a greater percentage of the blood being red blood
cells and the blood volume fill graph will trend downwards and approach
the alert level. The BV alert level is drawn as a blue dotted line across the
BV graph.
The following is displayed to the right of the BV graph:
Feature Function
Current blood volume change profile – The profile starts
calculating after the first two blood volume measurements and
is computed over the previous 15 minutes of data. The profile
can be:
A BV change is less than or equal to -3% per hour
(default)
B BV change is more than -3% and less than or equal to
-6.5% per hour
C BV change exceeds -6.5% per hour
Current Hematocrit value.
Current estimated Hemoglobin value calculated from the
current Hematocrit:
Hb = Hct/2.94
Blood Volume Change – The percent change in blood volume
since the start of the treatment. The BV change value is
calculated from the following equation:
∆ BV% =
[(Hct initial/Hct current) – 1] x 100
BV Alert Level button – Sets the BV (Blood Volume) Alert
Level (under physician direction). When the current ∆ BV%
drops below the set BV alert level, the 2008T hemodialysis
machine stops the UF pump and displays the alert message
“Rel. Blood Volume Low”. The alert can be cleared by lowering
the alert level or by setting the BV Alert Level to OFF. After
clearing the alert, the UF pump will automatically turn back on
to the UF Rate set on the “Home” screen.
To set the BV Alert Level, select the
BV Alert Level button
and enter the desired value using the  or  (up or down)
keys or the numbers on the keyboard and press the CONFIRM
key. To turn the BV Alert level OFF, enter “0” (zero) on the
keyboard and press the
CONFIRM key.
The BV Alert Level can be set from -1 to -20 or 0 for OFF. The
default setting is -15. The BV alert level is drawn as a blue
dotted line across the BV graph.
