PROCESSING
TIME
Cell Saving
The time required to process a centrifuge bowl of salvaged blood depends
on the following factors:
!
Salvaged blood hematocrit.
!
Bowl volume.
!
Bowl filling rate.
!
Wash volume.
!
Wash flow rate.
!
Empty flow rate.
All these factors combine to determine the total processing time for any cell
salvage system. The CS5+ device has been programmed to optimize this
time during each procedure without compromising the final product. Any
changes made to the preset processing parameters should be carefully
considered prior to being executed.
Sequestering
Typical processing times for performing the sequestering procedure with the
CS5+ device are from 25 to 40 minutes. During this time approximately
1200 to 2500 ml of whole blood will be processed, resulting in the collec-
tion of 1.5 to 3.0 x 10e11 platelets in 500 to 1600 ml of plasma. Actual time
and results may vary depending on individual variability in vascular access,
patient tolerance to the sequestering procedure, surgical condition, height,
weight, hematocrit and platelet pre-count.
