Manual Mode

You can enter Manual mode once you have primed the disposable tubing
set and entered donor/patient data.
Table 6-2 describes how the FLOW, INLET:AC RATIO, and SPIN
RPM keys function in Manual mode.
Caution: Enter complete donor or patient data before entering
Manual mode. Failure to do so may result in erroneous pump flow
rates once you enter Manual mode.

COBE Spectra™ Apheresis System • Essentials Guide
Function
During all procedures except TPE and WBC procedures, you cannot change the centrifuge speed in
Automatic mode. The Spectra system automatically changes the centrifuge speed during TPE, RBCX, and
WBC procedures when you change the inlet pump flow rate.
During TPE procedures, you can change the centrifuge speed to accommodate special circumstances that
require increased rpm to increase the separation factor or avoid platelet loss in the plasma.
During WBC procedures, you can change the centrifuge speed by changing the separation factor.
Description
Caution: The Spectra system does not automatically control
pump flow rates when operating in Manual mode.
In Manual mode, you can enter pump flow rates outside of the
performance specifications described in Chapter 13. Gambro BCT
makes no accuracy claim for values outside the specified
performance range for each pump. The Spectra system does not
perform run time valve checks in Manual mode.
Entering Manual mode during an LRS or LRST procedure may
result in WBC levels greater than 1 x 106. At the end of the
procedure, a screen appears indicating that the WBC and platelet
content of the product needs to be measured.
