Run a Case
9-4
Monitor
Monitor the patient and system controls and displays, adjusting the controls as
necessary.
Servo Control
Initiate servo control when appropriate and when pump flow rates and servo
setpoints have stabilized.
CPG Delivery
Utilize the Delivery subtab within the CPG tab to track cardioplegia delivery, employ
cardioplegia timers, and to deliver auto doses, if desired.
Messages
Respond to any message immediately. Should a centrifugal pump stop or go
to Coast speed, clamp lines. Always check the pump display and the CCM for
messages related to pressure, air bubble, and level detection. Determine the cause
of the alarm and take appropriate action (see the
CCM and Modules chapters,
messages section, and the messages sections at the end of the Roller Pump and
Centrifugal Control Unit chapters).
The message area at the top of the Perfusion Screen displays the highest priority
alarm, alert, status, or error message. If two conditions of equal priority exist at the
same time, the condition that was detected first will be displayed on the CCM until it
clears. If the second condition still exists after the first has been cleared, then that
message will be displayed.
Status messages post only once. If the message area has a higher priority message,
the status message will post only in the Messages subtab within the Aux tab.
All messages post in the Messages subtab within the Aux tab. The messages can
be viewed at any time during the case by pressing the Aux tab and opening the
Messages subtab. The subtab displays the messages and the time the message was
generated.
Battery
Monitor battery supply, when in use. Observe the power status indicator LED and the
battery charge level bar graph in the Power subtab within the System tab.
Ending a Case
When the case is finished, exit the case by touching the Post Case tab and following
the prompts. When the case is exited, the pumps will stop and the gas flow rate
will be set to zero. Any modifications to the Perfusion Screen will revert to default
settings or configured settings after the perfusion screen is exited. Modifications
could include patient data, gas blend, FiO2 alarm value, pump display units, pump(s)
and occluder responses to safety connections, minimum flow alarm value(s), level
detect mode, pressure display, pressure alert and alarm limit(s), temperature alarm
limit(s), cardioplegia volume tracking and autodose setup, messages in the Messages
subtab within the Aux tab, volume of the audio alarm, reassigned modules, and timer
value(s).
Note: When using the gas flow slide bar on the CCM to shut off the gas flow or when
ending a case, the gas flow knob may not return to its full off position and a small
amount of gas may still be flowing. Manually turn the gas flow knob clockwise until it
stops to completely stop the flow of gas.
Powering Down
Use the Shut down button on the main screen to perform a controlled shut down
of the system computer. Then power down the entire system using the AC (Mains)
power switch on the front of the system base.
