To Set the Width
1. Touch the Width button.
2. Use the large arrows to change the Width in increments of 10%.
3. Use the small arrows to change the Width in increments of 5%.
4. Touch the Width button again to store the new value. The recommended
minimum Width is 30%.
To Initiate Pulse Mode:
Do not initiate Pulse mode until perfusion has stabilized using continuous flow and a
mean flow has been determined.
While running in Continuous mode, start Pulse mode operation via the CCM:
1. Touch the Primary Pump icon to access the Primary Pump tab.
2. Select the Pulse subtab.
3. Touch the Auto button.
The Baseline speed decreases from 100% to the selected percent at a rate of 5% every
2 seconds. The pump message area displays the message "RAMP: BASELINE XX%"
(where XX is the current Base setting) until the desired setting is reached.
The Primary Pump display shows the Pulse mode symbol next to the average RPM
or L/min.

Pulse Operation
Adjust the average flow by adjusting the peak speed using the pump speed control
knob or the pump control slide bar. The average speed/flow rate is calculated from
the Peak, Base, and Width. The Pulse mode parameters can be adjusted during use.
Note: When monitoring the arterial pulse peak from the patient, the maximum peak
pressure is achieved at the pump outlet; this pressure pulse will be dampened by
perfusion components such as a long arterial line, a constrictive arterial cannula, and
the positioning and compliance of membrane oxygenators and filters in the arterial
line.
To End Pulse Mode
Use one of the following three options:
• Press the Manual button on the pump control panel and the pump transitions to
Continuous mode. The new Continuous mode speed/flow rate is calculated to
match the Pulse mode average speed/flow rate.
Open the Pulse subtab within the Primary Pump tab on the CCM, touch
•
the Manual button, and the pump transitions to Continuous mode. The new
Continuous mode speed/flow rate is calculated to match the Pulse mode average
speed/flow rate.
• Open the Pulse subtab within the Primary Pump tab on the CCM. Slowly
increase the Base setting to 100%. Note that although the flow will be
continuous, the pump still operates in Pulse mode.
