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 plasma and saline are returned to the donor.
Typical Main Collection Screen – Return
Phase
After plasma 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 product volume icon continuously displays the
amount of red cells that have been collected in the red cell
container.
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 additional information regarding Intelligent Flow Control.
