HeartWare® Ventricular Assist System Patient Manual
^ Immediate action required, and then call your physician, nurse or VAD coordinator
ALL high alarms will display a message on the Controller Display and the Alarm Indicator will flash
red. The VAD will stop if the driveline is disconnected or if the controller fails. For a "VAD Stopped"
alarm, the text message will tell you whether to connect the driveline or change the controller, as
both of these situations may trigger this alarm.
The "Controller Failed" alarm indicates a potential controller failure; the controller should be
exchanged with the back‐up controller.
WARNING! ALWAYS switch to the backup controller if there is a "Controller Failed"
alarm.
The "Critical Battery" alarm is displayed when both batteries only have a few minutes of battery
time remaining to power your pump. Replace the depleted batteries with fully charged batteries or
use your AC adapter or DC adapter.
7.3 Medium Alarms
The medium alarm starts at a low volume and gets louder over the next minute, unless the Alarm
Mute button is pressed. A medium alarm is indicated by a flashing YELLOW Alarm Indicator, and the
text message tells you to call medical personnel. Please call your doctor or nurse immediately to
receive instructions.
