Factors Affecting Processing Time
Cell Salvage
The time required to process a bowl of salvaged blood depends on the
following factors:
Salvaged blood hematocrit
Bowl volume
Fill pump rate
Wash volume
Wash pump rate
Empty pump rate
All these factors combine to determine the total processing time for any Cell
Salvage system. The Cell Saver Elite 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.
Sequestration
Typical processing times for a single Sequestration cycle on the Cell Saver
Elite device are 7-25 minutes. During this time approximately 225 to 900 mL of
whole blood will be processed, resulting in the collection of 20 to 40 mL of
platelet rich plasma and 50 to 600 mL of platelet poor plasma. Platelet yields
are typically 3-7 times that of the incoming whole blood.
Actual time and results may vary depending on bowl size, protocol settings,
hematocrit of incoming blood, and platelet pre-count of the incoming blood.
