ALARMS OVERVIEW
The Automated Impella® Controller monitors various functions to determine whether specific
operational parameters are within expected limits. When a parameter goes outside of its
specified limits, the Automated Impella® Controller sounds an alarm tone and displays an alarm
message that can be viewed on the display screen on the front of the controller. The alarm tone
indicates the severity of the alarm. The alarm message on the display screen is color-coded for
severity and provides details on the cause of the alarm and how to resolve the alarm. After
muting an alarm, if another alarm occurs it will only be heard and displayed if it is a higher
priority alarm than the one that was muted.
ALARM LEVELS
Alarms are divided into three levels of severity:
• Advisory (white)
• Serious (yellow)
• Critical (red)
