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 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.
ALARM LEVELS
Alarms are divided into three levels of severity:
• Advisory (white)
• Serious (yellow)
• Critical (red)
