Impella® Skills Video: Entering Cardiac Output


This Impella skills video demonstrates how to enter cardiac output into the Automated Impella Controller™ (AIC) for Impella CP® with SmartAssist® and Impella 5.5® with SmartAssist®. The AIC continuously calculates cardiac output (CO) and cardiac power output (CPO) but requires a CO value to be entered every 8 hours.

Enter the reference cardiac output, which is the patient’s total cardiac output, immediately following a reference measurement.

  1. Press the MENU soft button
  2. Using the selector knob, scroll to and select “Enter Cardiac Output”
  3. Enter the patient’s total cardiac output by adjusting the displayed value using either the selector knob or the up and down soft keys
  4. Select DONE

Following cardiac output entry, the AIC will automatically calculate CPO. If the CPO is less than or equal to 0.6 watts, the value will be displayed in yellow.

The AIC will continuously update CO and CPO for up to 8 hours. CO should be entered every 8 hours, or if there is a change in the patient’s vascular state. A white notification to enter a new cardiac output will appear 7 hours after the last CO entry. If a new CO value is not entered after 8 hours, the CO value will display as dashes until a new CO value is entered.


The cardiac output and cardiac power output metrics are for informational purposes only and should not be used for diagnostic purposes or for patient monitoring
