Pulse Mode - Terumo Advanced Perfusion System 1 Operator's Manual

Roller Pumps
Ending Continuous Mode
Pressing the Stop button on the CCM or the Start/Stop button on the front panel will
stop the pump.
WARNING: Always check the pump for proper operational mode after a Pause
or Reduce Speed response has been executed. A pump may go to Stop mode
and need to be started manually if the pump has received multiple high priority
messages.

Pulse Mode

When using Pulse mode during a case, monitor the patient waveform on the
operating room monitor. 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.
A pulse cycle consists of one high speed period (Peak) and one low speed period
(Base). The high speed is controlled by the pump speed control knob or the pump
control slide bar CCM and the low speed is determined by the Base setting. The high
speed is displayed on the slide bar and the average speed is displayed in the pump
control box and the pump local display. The amount of time the pulse cycle is at the
high speed is determined by the Width setting. The Rate defines how many pulse
cycles will occur per minute.
Pulse Parameters
The Rate, Base, and Width must be set up using the CCM:
Note: Changes to the Width and Rate are initiated after the new value is stored.
Changes to the Base are sent as the value is changed.
