SUCTION DETECTION DURING SENSOR DRIFT OR
SENSOR FAILURE
If sensor drift occurs or the pressure sensor fails, the controller can no
longer detect suction.
(For more information about suction, refer to the Suction discussion
earlier in this manual.)
Note: The effectiveness of Impella 5.0 or Impella LD Catheter
support can only be assessed by monitoring patient hemodynamics,
cardiac imaging, and the Impella 5.0 Catheter motor current.
Signs of suction Include the following:
• A drop in the patient's arterial pressure
• Decreased output, if a cardiac monitor is in place
• Dampened or flat motor current waveforms
If imaging reveals that the suction is caused by the catheter inlet area
in close proximity to the intraventricular wall, reposition the catheter
as described in Table 5. If hemodynamic parameters, such as low aortic
pressure or high pulmonary artery pressure, indicate suction caused by
inadequate filling volume, reduce P-level and follow the management
strategies described in Table 5.
ENABLING PURGE FLOW NOTIFICATIONS
The purge flow notification white alarms Purge Flow Increased and
Purge Flow Decreased ) are disabled by default.
To Enable these alarms:
1. Press MENU and scroll to Settings/Services. Press the selector
knob.
2. Scroll to Enable Purge Flow Change Notifications and
press the selector knob to enable these alarms.

DISABLING AUDIO ALARMS
The audio for the following alarms can be disabled:
• Placement Signal Not Reliable
• Placement Signal Low
• Placement Signal Lumen Blocked
• Suction
• Purge System Blocked / Purge Pressure High
To disable the audio:
1. Press MENU and scroll to "Settings/Services."
Press the selector knob.
2. Highlight alarm and press the selector knob to disable the audio
for the selected alarm.
SURGICAL MODE
Surgical Mode can be enabled to silence the Impella Stopped alarm
that occurs when P-level is reduced to P-0. A white banner notification
displays throughout the duration of Surgical Mode support.
To Enable Surgical Mode:
1.
Press > MENU and scroll to > Settings/Services.
Press the Selector knob.
2. Scroll to > Enable Surgical Mode,
Press the Selector knob to enable it.
You can Disable Surgical Mode in one of two ways:
1. Increase P-level above P-0, or
2. Press MENU, select > Settings/Services,
then select > Disable Surgical Mode.
TIMED DATA RECORDING
The Automated Impella Controller can hold up to 24 hours of real-time
data. Once memory is full, the controller starts overwriting the old data.
The timed data recording feature allows you to permanently save real-time
operating data for later analysis. Timed data recording is automatically
turned on during certain alarm conditions to capture data for analysis. You
can also manually turn on the feature at any time to capture data for later
analysis.
To manually access the timed data recording feature:
1. Press MENU and scroll to "Start Data Snapshot." Press the selector
knob.
2.
The controller records data for a predefined period of 10 minutes.
OPERATING THE IMPELLA CATHETER IN
ELECTROMAGNETIC FIELDS
The Impella Catheter contains a permanent magnet motor that emits an
electromagnetic field. This field may produce electromagnetic interference
with other equipment. In addition, other equipment that emits a strong
electromagnetic field may affect the operation of the Impella Catheter
motor.
