ADJUST LV PLACEMENT SIGNAL
Adjust the LV placement signal to reduce potential measurement variability.
Adjust the LV Placement Signal when the white notification appears on
the screen. The notification appears first when a suggested adjustment
is calculated. If a suggested adjustment is calculated, then a second
notification will appear after 24 hours of pump use.

ENTERING CARDIAC OUTPUT
The cardiac output and cardiac power output metrics are for informational
purposes only. Do not use for diagnostic purposes or patient monitoring.
Independently verify all parameters displayed with a cleared or approved
diagnostic device.
Enter Cardiac output into the Automated Impella Controller from a
reference device, such as a Swan-Ganz catheter. Enter a new cardiac
output every 8 hours. After 7 hours from entry, a white notification will
trigger to enter a new cardiac output.
To enter the Cardiac Output:
1.
Press MENU soft button.
2.
Select "Enter Cardiac Output" using the rotary knob or the up/
down arrow soft buttons.
3.
Enter the total Cardiac Output, which can be any value from 0.0
to 10.0 L/min in increments of 0.1 L/min.
4.
Press the DONE soft button or the rotary knob to complete.
Figure 1.18 Enter Cardiac Output
A Cardiac Output Confirmation will be displayed if a total Cardiac Output is
entered that is less than or equal to the current Impella Flow (Figure 1.19).
The CONFIRM soft button will use the current Impella Flow as the total
Cardiac Output entry and the Native Cardiac Output will not be trended.
The BACK soft button will go back to the Enter Cardiac Output screen. The
CANCEL soft button will exit the workflow.
