10 Monitoring SpO2
174
– Another SpO
2
sensor in close proximity (e.g. when more than one SpO
2
measurement is
performed on the same patient). Always cover both sensors with opaque material to reduce
cross-interference.
– Electromagnetic interference, especially at perfusion indicator values below 1.0 or signal
quality indicator below medium.
– Excessive patient movement and vibration.
Understanding the SpO2 Numerics
In automatic mode, you may see the time until the next measurement instead of the timestamp,
depending on your configuration. The time is shown like this:
When an automatic measurement is ongoing, the numerics are replaced by horizontal bars (1, 2 or 3
bars, in turn).
SpO
2
numerics from intermittent measurements (from the IntelliVue CL SpO
2
Pod or a telemetry
device) can be configured to be grayed out or to disappear from the screen after a set time. This avoids
older numerics being misinterpreted as current data. The time can be set in Configuration mode.
SpO2 Signal Quality Indicator (FAST SpO2 only)
The SpO
2
numeric is displayed together with a signal quality indicator (if configured and enough space
is available) which gives an indication of the reliability of the displayed values.
1 Measurement Mode (only with the IntelliVue CL
SpO
2
Pod, in Auto or Manual mode)
2 Repeat time (only with the IntelliVue CL SpO
2
Pod, in
Auto mode)
3 Timestamp for numerics (only with the
IntelliVue CL SpO
2
Pod or a telemetry device)
4 Pulse numeric
5 Perfusion Numeric
6 Alarms off indicator (here for Pulse alarms)
7 SpO
2
numeric
8 SpO
2
alarm limits
9 Signal Quality indicator
