Centrifuge Stop (Centrifuge Stop Recovery) Substate
This recovery procedure occurs anytime after the centrifuge stops (or drops below a predetermined
speed). This recovery procedure takes precedence over the other recovery procedures. The centrifuge
ramps up to its final commanded speed while the pumps are maintained at low speeds to prevent the
occurrence of a spillover or air block. When the centrifuge reaches the commanded speed plus 60 more
seconds, the pumps return to their normal collection speeds.
Centrifuge Slow (Centrifuge Slow Recovery) Substate
This recovery substate occurs if the centrifuge actual speed drops below a predetermined speed, but is
greater than a predetermined speed. The centrifuge ramps up to 3000 rpm and this recovery continues
for 15 more seconds.
Saline Bolus (Saline Bolus Recovery) Substate
This substate occurs whenever a saline bolus is administered. The platelet pump runs at a predetermined
speed until a predetermined volume of saline bolus is delivered. At the same time the return pump runs
at the same speed to keep the reservoir volume approximately even. After a predetermined volume of
saline has been pumped, the Trima Accel system resumes the draw or return cycle that it was previously
in.
Saline Prime (Replacement Fluid Priming Recovery) Substate
This substate occurs the first time replacement fluid is administered in an RBC/Plasma procedure. The
platelet pump runs at a predetermined speed until a predetermined volume of saline is pumped to prime
the replacement fluid line.
WBC Chamber Purge (WBC Chamber Purge Recovery) Substate
This substate occurs during any procedure where a spillover recovery occurs or a very large inlet volume
is processed. The plasma pump increases in speed and the platelet pump stops, purging volume from the
LRS chamber. This continues until a predetermined plasma volume is pumped through the LRS
chamber.
RBC Chamber Purge (RBC Chamber Purge Recovery) Substate
This substate occurs during any procedure where a platelet, plasma, RBC tubing set is loaded. This
recovery substate always occurs at the beginning of the Channel Setup substate. The plasma pump runs
at a predetermined speed and the platelet pump stops, purging volume from the LRS chamber. This
continues until a predetermined plasma volume is pumped.
Plasma Valve Motion (Plasma Valve Move Recovery) Substate
This substate occurs whenever the plasma valve changes position during a platelet collection procedure.
This recovery stops the pumps for one second while the valve moves to prevent fluid from entering the
plasma bag while the valve moves through the open position.
