Action
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
through MENU soft key.

Cause
Motor speed has been reduced in response to suction.
Impella Catheter position unknown due to low
pulsatility.
Impella Catheter position unknown detected by
algorithm.
User has disabled Placement Monitoring.
Placement signal pulsatility is low and placement signal
amplitude is high (>130mmHg) for 30 consecutive
seconds.
Retrograde flow has been detected and minimum
motor speed has been increased to more than target
P-level.
Incompatible purge cassette RFID version.
Purge flow has decreased by ≥2.5 mL/hr.
Purge flow has increased by ≥2.5 mL/hr.
There are 30 mL (in addition to 5% of the starting bag
volume) or fewer remaining in the purge fluid bag.
Surgical Mode has been enabled to silence "Impella
Stopped" alarm at P-0.
Follow instructions or press MUTE ALARM to clear the
alarm for 30 minutes.
The optical sensor is not supported with the current
version of the controller hardware.
The pump will still operate without placement or
suction monitoring.
Unexpected restart of controller due to software of
