2008T Hemodialysis Machine with CLiC Device User’s Guide P/N 490206 Rev E 19
The Hct (Hematocrit) graph
Note : To display the Hematocrit graph on the “Crit-Line” screen
instead of the default BV graph, call a qualified service
technician.
The Hct (Hematocrit) graph is a line graph drawn from the previous
hematocrit 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
hematocrit line graph will trend upwards and approach the alert level.
The Hematocrit Alert Level is drawn as a black dotted line across the Hct
graph. The Hematocrit Alert Level cannot be set directly, but is calculated
from the BV Alert Level (see the
BV Alert Level button, on page 15 for
more information). The line will appear on the graph after the initial Hct is
determined. When the alert is triggered, 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 following features pertain to the Hematocrit graph:
Feature Function
Initial Hct – The initial hematocrit (Hct) value is recorded
along with the first data point when graphing begins.
Initial est. Hb – The estimated initial hemoglobin (Hb) value
is recorded along with the first data point when graphing
begins. It is calculated based on the hematocrit reading.
Current blood volume change profile – See page 15 for
more information.
Current Hematocrit value.
Current estimated Hemoglobin value calculated from the
current Hematocrit:
Hb = Hct/2.94
Blood Volume Change – See page 15 for more information.
