Roller Pumps
5-2
In the Configuration area of the Central Control Monitor, a roller pump can be
designated as primary, backup, cardioplegia, master, follower, or none. Each of these
has unique functionality as described in the table below.
Function CCM Features Unique Functionality
Primary • Dedicated pump slide bar • Pulse mode* operation
• Choice of RPM or L/min, • Initiate a response in a connected occluder
L/min/m
2
or mL/kg/min display
Backup • Primary pump functionality can be
reassigned to a pump of the same or
different type.
Cardioplegia • Shared slide bar • Automatic cardioplegia dose delivery
• CPG tab tracks time and volume
of cardioplegia delivery
Master • Master and follower controls and • Master slide bar controls follower
data displayed in one control box pump speed
• Display total volume from master and follower
pumps
Follower • Master and follower controls and • Follower slide bar controls master/
data displayed in one control box follower pump ratio
• Tracks master
*The use of the term “Pulse mode” refers to the variable pressure and flow waveforms that result from the cyclic
operation of the primary pump. Replication of a physiologic pulse from a natural heart is not obtained with a
pump speed controller. No claim of clinical benefit from the use of the Pulse mode has been reviewed by global
Regulatory Agencies.
When operating a device that shares a slide bar location, make sure that the slide bar
displayed is for the device you intend to operate. The device name should appear at
the top of the slide bar and the corresponding color should appear on the central strip
and scroll control.
When a roller pump is designated as the primary pump, the system provides the
capability to operate the pump in Pulse mode. In this mode, the user can select the
pulse parameters for the Base, Width, and Rate and initiate pulse operation from the
Central Control Monitor.
The system provides the capability to automatically regulate the roller pump speed
to maintain a selected pressure or flow setpoint. This is known as Servo mode. In
this mode, the user selects a pressure or flow source and initiates servo operation on
the Central Control Monitor. Once in Servo mode, the servo setpoint can be changed
by adjusting the pump speed control knob or using the pump control slide bar on the
Central Control Monitor.
Safety connections such as air detection, level detection, and pressure monitoring
are configured using the Configuration area on the Central Control Monitor. Pump
responses to alerts and alarms are user selectable. Valid responses for roller pumps
are Stop, Pause, Reduce Speed, Message Only, or No Response. The local display
will display a message indicating the event from a connected device.
