Refer to flow estimates in table below.
Monitor patient hemodynamics.
1. Press the Purge Menu soft key
2. then select Change Purge Fluid Bag.
Software installation was unsuccessful. Reinstall
software.
1. Reduce P-level.
2. Check Impella position.
3. Check filling and volume status.
Controller is running on battery power.
The audio for the following alarm has been
disabled.
<Alarm will be listed here>
1. Connect controller to ground during air transport.
2. If equipped with Impella Connect, enable Flight
Mode on module.
3. Upon arrival at receiving hospital, disable Flight
Mode under MENU.
1. Reduce P-Level
2. Check Impella position.
3. Check filling and volume status.
Impella position unknown due to low pulsatility,
assess cardiac function.
Confirm Impella position with imaging.
Monitor Impella position with imaging or re-enable
Placement Monitoring under MENU and Settings/
Service.
Placement and Suction Monitoring are suspended.
Aspirate with syringe, then flush.
Impella P-level has increased to prevent retrograde
flow.
1. Consider increasing target P-level.
2. For weaning, disable Retrograde Flow Control
