Technical Alarms
The VS30 monitor is designed so that you can easily move it from one patient to another
to take vital signs measurements without sounding alarms. However, you can also use
the monitor for extended monitoring of an individual patient by placing the monitor in
Interval or Continuous monitoring mode. See “Monitoring Mode Menu” on page 2-18 for
more information.
Because the SpO2 Non-Pulsatile and SpO2 No Sensor technical alarms are not useful if
you connect and disconnect sensors between patients, these alarms are only enabled
when the monitor is in Interval or Continuous monitoring mode. If the sensor falls off or
becomes disconnected from the monitor when operating in these modes, a high-priority
alarm occurs.
If the monitor is not in Interval or Continuous monitoring mode, the SpO2 Non-Pulsatile
and SpO2 No Sensor technical alarms are disabled, which allows you to remove the
SpO
2
sensor from a patient without sounding alarms.
WARNING
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.
The SpO2 Numeric Pane
The following illustration shows the components of the SpO2
numeric pane. The SpO
2
pleth waveform appears by default in Spot Check monitoring mode.
In Interval and Continuous monitoring modes, the waveform is hidden by default. A
Waveform icon enables you to show the pleth waveform.
If the alarm audio is turned off for this measurement, the Audio Off icon appears in the
lower left of the pane.
If SpO2 Source is set to Manual Input, the phrase Manual Input appears in the lower left
of the pane.
