To Set the Base:
1. Touch the Base button.
2. Use the large arrows to change the Base in increments of 10%.
3. Use the small arrows to change the Base in increments of 5%.
4. Touch the Base button again to store the new value. The recommended
minimum Base is 50%.
To Initiate Pulse Mode:
Initiate Pulse mode only when a stable continuous flow at a speed >1550 RPM has
been established.
Start Pulse mode operation via the CCM:
1. Touch the Primary Pump icon to access the Primary Pump tab.
Select the Pulse subtab.
2.
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.
Always adjust the centrifugal pump speed when changing to Pulse mode as the
average flow rate will decrease and the speed may be too low, resulting in retrograde
flow.
The primary pump display shows the Pulse mode symbol next to the primary display.
Pulse Mode Symbol
Pulse Operation
Adjust the average flow by adjusting the pump speed control knob or the pump
control slide bar on the CCM.
CAUTION: During Pulse mode pumping, because of variations in flow, the
flow rate displayed is an approximate value.
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.
