The Hct (Hematocrit) Graph; The O2 Sat (Oxygen Saturation) Graph; The Bp (Blood Pressure) Graph - Fresenius Medical Care 2008T Operator's Manual

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 Hct (Hematocrit) graph

The Hct (Hematocrit) graph is a line graph (Figure 55 on page 120) 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 121). The line will appear on the graph after the initial
Hct is determined. When the alert is triggered, 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.

Note: To switch between the O
"Press Confirm to switch to O2 graph. Press Escape to return to BP graph." or
"Press Confirm to switch to Blood Pressure graph. Press Escape to return to O2
graph." is displayed. Press the CONFIRM key to confirm the selection.
To switch back to the previous graph, select the graph again and press the CONFIRM key
to confirm the selection.

The BP (Blood Pressure) graph

Similar to the Blood Pressure graph on the "Trends" and "Blood Pressure" screens, the BP
(Blood Pressure) graph (Figure 55 on page 120) is drawn as a series of black dumbbells
between the systolic and diastolic blood pressures. On the "Crit-Line" screen, the systolic
(upper) and diastolic (lower) numbers are also displayed. If the value is out of range (as
specified by the parameters on the "Blood Pressure" screen), the dumbbell will be drawn in
red.
Note: If there is not enough space between blood pressure measurements, the blood pressure
graph will not display a measurement in order to prevent overlap.
Note: Markers do not appear on the Blood Pressure graph.
