4.2 HVAD
®
Controller (continued)
Electrostatic Discharge (ESD)
Static electricity is widely present and more so in certain conditions such as in drier environments
and in the vicinity of certain materials and fabrics such as silk clothing and carpeting. Discharge
of static electricity, commonly referred to as electrostatic discharge (ESD), may interfere with
electronic equipment. The HVAD
®
Controller, as a piece of electronic equipment, is
susceptible to ESD. Be aware of ESD and its potential to cause disruptive and possibly fatal faults
in susceptible patients.
The controller may alarm in certain situations as a result of ESD. These alarms include:
1. A [Controller Failed] alarm.
2. A high audible alarm without accompanying alarm text on the Controller Display.
3. A [Controller Fault] alarm.
Alarms”), since there are a number of potential causes for this alarm.
To reduce the chance of ESD damage to the controller instruct patients to:
1. Make good connections when changing power sources
disconnected controller power port.
have a caregiver nearby in case an alarm occurs.
to change the power sources.
2. Be careful near materials and electronic devices prone to static electricity, such as: carpeted
screens.
In order to avoid or minimize the potential for ESD occurrence, follow good power/battery
connection techniques as described in the IFU and patient manual.
WARNING! AVOID devices and conditions that may induce strong static discharges (e.g., television or
computer monitor screens) as electrostatic discharges can damage the electrical parts of the system
and cause the LVAD to perform improperly or stop.
