HeartWare® Ventricular Assist System Patient Manual
Guide to Controller Display, Buttons, and Indicators (Refer to Figure 4)
The CONTROLLER DISPLAY gives pump information
including impeller speed (RPM), power (Watts), and blood
flow (L/min). When an alarm occurs, the pump
information is replaced by two lines of text that tell you
what the alarm is and what to do. Section 7 , "Alarms",
describes alarms in detail.
The AC/DC INDICATOR will be green if you are using the
AC adapter or DC adapter to power the controller.
The two BATTERY INDICATORS located on the top of the
controller are labeled "1" and "2". Either the "1" or "2"
will be lit, depending upon which port is providing primary
power. If an AC or DC adapter is connected, this will be
the primary power source.
The Battery Indicators tell you approximately how much
power remains in each battery.
 75‐100% battery capacity: 4 GREEN lights
 50‐74% battery capacity: 3 GREEN lights
 25‐49% battery capacity: 2 YELLOW lights
 24% or less battery capacity: 1 RED light
Note: If the AC adapter or DC adapter is connected to the
controller, the corresponding Battery Indicator will not
display lights but the corresponding "1" or "2" will be lit.
The ALARM INDICATOR lights when one or more alarms
occur. The Alarm Indicator changes colors depending on
the severity of the alarm and always displays the most
severe alarm in the case of multiple alarms. The display
for each alarm priority includes:
 High Alarm: Flashing Red
 Medium Alarm: Flashing Yellow
 Low Alarm: Solid Yellow
The ALARM MUTE BUTTON will silence (mute) a low or
medium alarm for 5 minutes or until a new alarm occurs.
A high alarm cannot be silenced. Call your clinician for all
medium and high alarms.
