Auditory Alarm Indicators
Auditory Alarm Indicators
The alarm decibel level and tone duration depend on the alarm priority.
If an alarm condition exists for more than one alarm priority, the highest level alarm
determines the decibel level and tone interval.
You can change the following auditory alarm settings:
• Alarm volume — You can increase or decrease the alarm volume. Always ensure that
the audio volume is appropriate for the environment. See “Silencing, Acknowledging,
and Pausing Alarms” on page 4-13. The relative decibel levels of different alarm
priorities are maintained.
• Alarm tones — The VS30 monitor offers two sets of alarm tones: Philips and IEC. The
alarm tone is selected by your system administrator.
• Silence — You can pause alarms or silence alarms indefinitely. See “Silencing,
Acknowledging, and Pausing Alarms” on page 4-13.
To verify that the speaker is working at any time, perform the procedure in “Testing
Alarms” on page 4-17.
WARNING
Never pause or turn off an auditory alarm or decrease the alarm volume if this action could
compromise patient safety.
Do not rely exclusively on the auditory alarm system for patient monitoring. The most reliable method
of patient monitoring requires correct operation of the monitor and close in-person observation and
assessment of the patient.
