sorin XTRA - Protocol Parameters (PPP and PRP)

Preoperative Sequestration (PPP and PRP)
10-24
20077/021 US XTRA Operator’s Manual
Empty Phase
The Empty phase of the PRP2 protocol, during which the remaining blood components in the bowl are
transferred to the RBC bag, is identical to that of the PPP and PRP1 protocols detailed in “PPP” on
page 10-22. Before the Empty phase begins, the operator will be prompted to close the PRP line and
open the PPP line so air can enter the bowl during emptying.
Protocol Parameters (PPP and PRP)
The table below contains the parameters recommended by LivaNova for the PPP and PRP protocols,
according to the bowl size used.
Note: Every time a new case is started, factory procedure parameters are reinitialized to their
default values, even if the unit is not shut down and restarted.

These parameters, Centrifuge Speed in the Fill and in Spill phases, are related to each other: Spill Centrifuge Speed must always be lower
than Fill Centrifuge Speed.
