In the Automatic mode the wash volume is programmable from 750 - 3000 ml
(500 - 3000 ml for a 125 ml bowl, 300 - 3000 ml for a 70 ml bowl). The
recommended wash volume for a 225 ml bowl is 1000 ml(750ml for a 125 ml
bowl and 300ml for a 70 ml bowl).
Washing Partial
Bowls
In general, filling the bowl to a lower hematocrit will necessitate a higher volume
of wash solution to achieve adequate washout. Because the hematocrit of the
bowl contents is lower, there is more supernatant in the bowl. In order to dilute
the larger volume of supernatant, two times the normal wash solution (usually 2
x 1000 ml) is needed.
Emptying the
Bowl
After the minimum volume of wash solution has been introduced and when the
effluent line sensor detects adequate washing, the wash line is closed and the
reinfusion line is opened. The pump then reverses direction and pumps
concentrated RBCs suspended in wash solution from the bowl to the reinfusion
bag.
The above cycle, FILL-WASH-EMPTY, is repeated as often as blood loss requires.
The Reservoir Level Sensor will initiate additional cycles as blood begins to be
collect again reaching the predetermined levels.
