Return Phase
A one-note chime sounds and the green signal light on top of
the instrument flashes to inform the operator that the first
return cycle is starting. During the return phase, the blood in
the in-process container is pumped to the centrifuge for
processing, while collected red cells and saline are returned to
the donor.
Typical Main Collection Screen – Return Phase
After red cells and saline are reinfused to the donor and the
anticoagulated whole blood in the in-process container has been
processed, the instrument begins another draw phase. This
process of draw-return phases continues until the collection is
complete. The
red cell product volume icon and the plasma product
volume button continuously display the amount of red cells and
plasma that have been collected.
No changes can be made to the red cell product volume. The
plasma volume can be adjusted via the
plasma product volume button .
For additional information refer to Chapter 3, Making
Adjustments, Target Plasma Volume.
The instrument may return fluids to the donor at a rate equal to
or less than the default; however, it will not return fluids at a rate
greater than the default. The rate is determined by the
instrument at the beginning of each return phase and is
dependent upon the amount of anticoagulated whole blood in the
in-process container, the amount of fluid that must be returned
to the donor, the donor parameters entered into the procedure
by the operator, and the Intelligent Flow Control. Refer to
Chapter 3 for more information.
