Description
The X
TRA
system is equipped with indicators that monitor the quality of blood processed using the
intraoperative or postoperative protocols:
• Hematocrit (Hct) indicator - measures the hematocrit (%) of fluid entering and of RBCs leaving
the bowl.
• Waste Line Color (WLC) indicator - measures the color of the fluid in the waste line.
• Supernatant Removal Indicator - calculates the removal of supernatant during the Wash phase.
Figure 12-1 Location of the Hct and WLC Indicators
Together, these indicators and the user interface elements associated with them offer the operator
useful feedback and options for managing the quality of each case.
WARNING
Once the setup is completed, it is highly recommended not to alter
the position of the cassette and the tubes. Any alteration might
invalidate the calibration of the indicator.
CAUTION
Whenever the hematocrit value is relevant to the patient’s treatment, it is
always necessary to use other hospital standard measuring instruments.
