Latched and Non-Latched Alarms
4-6 EarlyVue VS30 Instructions for Use
Speaker Malfunction Alert
Speaker functionality is automatically monitored every 15 seconds when no alarms are
active. If a speaker malfunction is detected, the following occurs:
• A flashing red box with the text AUDIO FAILED appears in the technical message
pane of the information bar.
• The message Speaker Malfunc appears against a cyan background in the technical
message pane of the information bar.
For information on manually testing the speaker, see “Testing Alarms” on page 4-17.
WARNING
Auditory alarms do not sound when the AUDIO FAILED message is displayed. If this message
appears, do not use the monitor. Contact your system administrator for repair.
Latched and Non-Latched Alarms
When a non-latched alarm occurs, the auditory and visual alarms stop when the
condition that triggered the alarm ends. For example, if a cable becomes disconnected,
the alarm ends when the cable is reconnected. Most alarms are non-latched. Non-
latched alarm conditions of any priority present alarms for a minimum of 5 seconds, even
if the condition ends before 5 seconds elapses.
A latched alarm continues even after the condition that caused the alarm has resolved
itself. An SpO
2
Desat alarm is an example of a latched alarm. If an SpO
2
Desat alarm
occurs and the SpO
2
value returns to normal, the alarm will continue to sound to notify
you of the event.
A latched alarm continues until you acknowledge the alarm by touching the
Acknowledge Alarm button.
The following alarms are always latched:
• SpO2 Desat
• NBP Overpressure
• Loss of Monitoring
• awRR Apnea
• System Error
By default, the alarms listed above are latched and all other alarms are non-latched.
However, if your system administrator has enabled the Latch Physiological Alarms
option, all physiological alarms are latched and will continue to generate auditory and
visual alarm indicators until you acknowledge the alarms by touching the Acknowledge
Alarm button.
