NetGuard Alarms Technical Alarms
3.4 Technical Alarms
Technical alarms are patient specific and are related to technical issues that occur with
cables, leads, battery status, and device status.
3.4.1 Alarm Behaviors
The visual and audio indicators associated with a Technical level alarm are:
Visual Indicators
Technical alarms are automatically displayed in the Deferred Application Bar beside the
NetGuard Monitor view.
Audio Indicators
During a Technical alarm, the terminal releases audible tones, provided a physiological
alarm is not already in progress.
3.4.2 Technical Alarm Types
Technical alarm types include the following:
Lost Communication
A Lost Communication alarm indicates that the NetGuard device is not communicating with
the server. A Not Active alarm may also transition to a Lost Communication alarm after 30
minutes has elapsed.
NOTE: When a NetGuard device is in a Lost Communication state,
and a lethal System level alarm occurs, the device will
sound an audible notification but the terminal will not
provide any visual or audio notification until communication
with the server is restored.
Low Battery
A Low Battery alarm indicates that less than the minimum operating threshold of battery life is
remaining in the NetGuard Disposable. Typical battery life is three (3) days.
NOTE: To ensure continuous patient monitoring, discard and then
replace the reusable section of the NetGuard device when
the Low Battery message is displayed at the terminal.
Leads Inoperable
A Leads Inoperable alarm indicates that the device is unable to restore the ECG baseline
within 1000 msec. This could be caused by a defect in the electrodes, or failure of the
device.
Leads Off
A Leads Off alarm indicates that an ECG electrode is either detached or loose.
