Blood Run Collection Substates
The Blood Run state contains nineteen prime and collection substates and eleven recovery substates.
This section describes the prime and collection substates.
Channel Setup Substate
This substate continues to establish the interface until a predetermined inlet volume has been pumped.
The pumps begin ramping up in speed during this substate. After completion of this substate, the Trima
Accel system advances to Pre-Platelet Plasma, Pre-Platelet No Plasma, or Plasma Only substates
depending upon the chosen procedure.

Pre-Platelet Plasma (Pre-Platelet, Collecting Plasma) Substate
This substate occurs only in procedures where both platelets and plasma are collected. The plasma valve
is commanded to the collect position and the plasma pump speed changes to regulate the RBC line
hematocrit. The AC and inlet pump speeds change to keep the AC infusion rate at the run configured
value. After enough inlet volume has been processed to stabilize the LRS chamber, the Trima Accel
system advances to the Platelet Plasma substate or the Pre-Platelet No Plasma substate.
