Mid Run (Platelet Only Collection) Substate
This substate occurs after the Platelet Plasma substate (and the Platelet Concentration Adjustment
substate, if it occurs) to collect the remainder of the platelet product needed to reach the target yield.
This substate only occurs if more collected platelets are needed after the Concurrent Platelet Plasma
substate. During this substate the plasma pump runs slowly.

PIR (Platelet Inventory Recovery) Substate
This substate occurs after the Mid Run substate if the collect flow is less than a predetermined rate during
Platelet Only Collection. Otherwise, the Trima Accel system skips this substate and advances to the
Extended PCA substate. During Platelet Inventory Recovery the platelet pump ramps up in speed to its
maximum value and continues running until predetermined platelet volume has been pumped. The
Trima Accel system advances to the Extended PCA substate.
