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
When using Pulse mode during a case, monitor the patient waveform on the
operating room monitor.
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 on the 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 on the control unit local display. For the centrifugal control
unit, the Width – the amount of time the pulse cycle is at the high speed – is fixed at
50%. The Rate – the number of pulse cycles that occur per minute – is fixed at 60
beats per minute.
Pulse Parameters
The Base must be set up using the CCM:
1. Touch the
Primary Pump icon to access the Primary Pump tab.
2. Select the
Pulse
subtab.
