Additional Information
Pressure Transducer
The pressure transducer converts pressure into electrical signals detected by the
pressure module.
Primary Pump
A designation that is assigned to one pump in a Perfusion Screen, usually the arterial
pump.
Pulse Mode
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.
Primary pump function used to deliver Pulse mode flow for a roller or centrifugal
pump.
Pump Icon
Button with a roller or centrifugal pump symbol that, when pressed, opens or closes
the Pump tab.
Pump Summary
The area of the Pump tab used to view the pump flow, pump RPM, tube size or flow
constant (roller pump only), minimum flow alarm limit (centrifugal pump only), default
forward direction, and event-response list.
Pump Tab
The section of the Perfusion Screen used to view the pump summary, initiate Pulse
mode for the primary pump, initiate Servo mode, and view master or follower pump
status.
Reassign Module Subtab
The area in the System tab used to reassign the settings from one system
component to another.
Reduce Speed Response
A roller pump response to an event. The pump speed will decrease by 10% every
half second until the condition is cleared or the pump stops. A Reduce Speed
response to a pump start or pump stop event causes the pump speed to be reduced
by 10% and remain at this reduced speed.
Response
A pump or occluder action initiated by an event. Possible roller pump responses
are Stop, Pause, Reduce Speed, and Message Only. Possible centrifugal pump
responses are Stop, Coast, and Message Only. Possible occluder responses are
Open, Close, and Go to % Flow.
Safety Connection
A communication link set up between two system components allowing a device
to receive information from another device or module. Safety connections must be
set up in the Configuration area to enable devices to respond to events from other
devices or modules.
