WARNING
Switch to a backup Console, Motor and Flow Probe if any of the buttons
malfunction, if the display goes blank, and/or the main Console ceases to
operate.
WARNING
Switch to another Monitor if any of the buttons on the Monitor malfunction, if the
display goes blank, or if the Monitor ceases to operate.
8.1.2 Adjusting Pump Speed
Pump speed can be adjusted by first depressing the
SET RPM
keypad and then
depressing the
INCREASE
or
DECREASE
keypads. The available speed range is
between 500 and 5,500 RPM. The flow at a given RPM is dependent upon the position of
the drainage and return Cannulas, intravascular blood volume, patient’s hemodynamic
status, and resistance of the extracorporeal blood circuit components.
8.1.3 Manually Stopping the Pump
Depressing and holding the
STOP
keypad on the Console’s front panel for five seconds
manually stops the Pump if the Pump is running. While depressing the STOP keypad, the
message
TO STOP PUMP HOLD DOWN STOP KEY
will be displayed. The
FLOW
BELOW MINIMUM
alert message is then displayed (if a Minimum Flow Alarm Level is set)
and the audible alarm sounds.
WARNING
Only depress the Main AC Power Button to OFF when the System is no longer in
clinical use. To stop the Pump during patient support, depress and hold the
STOP keypad on the Console’s front panel for five seconds.
8.1.4 Restarting the Pump
If the Pump has been stopped, either manually or from an alarm condition, the user should
follow the Pump restart sequence described below.
WARNING
DO NOT attempt to restart the Pump after it has been stopped for more than 5
minutes without adequate anticoagulation, as the risk of thromboembolism is
increased after blood has remained stagnant in the Pump, circuit, and Cannulas.
