Cell Saving using Manual Operation
To avoid a red cell spillage into the waste bag, the operator can:
"
Press the Pause key and stop the pump.
The word “PAUSE” will flash on the screen display.
"
Press the Pump slew keys to gradually adjust the pump speed.
The operator can adjust the pump to the desired speed while observing the
cells for separation.
To resume the process at the previous pump rate:
"
Press the Pause key again.
Collecting fluid in the reservoir
The AC solution flow rate should be adjusted to be consistent with the rate
at which blood is collected at a 1-2 drops/second rate for heparin solution
(30,000 units of heparin in 1 liter of normal saline solution).
Initiation of the FILL state is largely dependent upon the rate of fluid collec-
tion in the reservoir. If the patient is losing blood steadily and rapidly,
processing may begin as soon as 100 ml of fluid enter the reservoir.
However, it is more typical to begin processing by initiating the FILL state
after the reservoir has accumulated 600-900 ml of volume.
Note: The reservoir volume will have a lower than normal hematrocrit due
to suction hemolysis, dilution by wound irrigants and dilution by heparin-
ized saline.
Filling the bowl
To initiate the FILL state, the operator can either:
"
Press the Start key.
or
"
Press the backlit Fill key.
The following information will be displayed:
