7 - 2 V Series Operating Instructions
7.1 General Alarm Behavior
The V 12/V 21 uses alarms to send notification when a patient’s physiological status changes, a
patient has a specific technical issue, or when there is a system violation. When a patient is first
admitted, the default system alarm settings are in effect. Modify individual patient alarm settings by
using the Alarms tab in the individual parameter dialogs. By default, alarm settings send notification
using:
• Visual indicators
• Audible indicators
The three alarm types used in this system include physiological, technical, and system.
7.2 Physiological Alarms
Physiological alarms indicate a violation of a monitored patient's physiological alarm thresholds or
arrhythmia analysis settings.
NOTE: Refer to "Alarms" on page 8-2 for additional information.
7.2.1 Alarm Behaviors
The visual and audio indicators associated with a physiological alarm are:
Visual Indicators
Visual indicators provide visual notification when an alarm threshold is violated. When a physiological
alarm condition is triggered, the digital data portion of the patient tile flashes (if the alarm priority is
set to high or medium), a text message displays in the digital tile, and, if configured, the alarm light
indicators flash, unless it is a low level alarm, in the corresponding alarm response color. The
physiological alarm behavior varies depending on the parameter, and on the alarm priority
associated with the parameter.
Audio Indicators
Audio indicators provide audible notification when an alarm threshold is violated. Audio indicators
may vary depending on the alarm severity, alarm type, system setup and configuration. Audio alarms
are triggered by:
• The onset of an alarm condition, provided the alarm delay is not active.
• A configured alarm delay, if alarm delay is active.
Once the alarm condition is resolved and/or silenced, the audible alarm stops, unless the alarm is
latched.
7.2.2 Alarm Options
The alarm options associated with a parameter dictate how the system responds when an alarm
occurs.
Latching
Alarm latching denotes that the audio and visual indicators, associated with an alarm condition, do
not automatically stop after resolving the patient alarm condition. After resolving the condition, it
must be acknowledged or the audio and visual alarm indicators continue.
The Navigator Area’s Alarm Acknowledge button temporarily silences the alarm condition for the
configured time period. However, if that latched alarm is not acknowledged during the configured
time period, the alarm indicators resume.
