N O Power Alarm; High Alarms - HeartWare Ventricular Assist System Patient Manual

a high alarm, you need to take immediate action. Please call your physician, nurse or VAD
coordinator for any high alarm or medium alarm. A low alarm reminds you to exchange a low
battery with a fully charged battery or to reconnect to a power supply (battery or AC/DC adapter). In
addition to the high, medium and low alarms, there is a "No Power" alarm that sounds if both
power sources are removed from the controller. (See "Quick Reference Guide for Alarms" in the
front of this manual, for a complete list of high, medium and low alarms.)
WARNING! ALWAYS replace a controller with a blank display or and/or no audible
alarms.
7.1 No Power Alarm
When both power supplies (batteries, AC adapter, DC adapter) are removed, there will be NO
message on the Controller Display. A loud continuous alarm will sound but the Alarm Indicator WILL
NOT light. Your pump has stopped. You need to connect two power supplies immediately. If this
does not resolve the alarm, immediately replace the controller with the back‐up controller.
WARNING! NEVER disconnect both power sources (batteries, AC adapter, DC adapter)
at the same time since this will stop the pump and activate the No Power alarm. At
least one power source must be connected at all times.
7.2 High Alarms
A high alarm is the loudest alarm; the Alarm Indicator on the controller is flashing RED and the text
message demands immediate action for VAD (pump) stoppage, controller failure or limited power to
run the pump. High alarms include the following:
