Displaying SIQ (for Masimo SpO
2
)
The signal quality indicator (SIQ) displays below the Pleth waveform. The SIQ is conveyed by vertical bars. The
height of the bar provides an assessment of the confidence in the displayed SpO
2
value. The SpO
2
SIQ can also
be used to identify the occurrence of a patient ‘s pulse.
The following picture shows the SpO
2
SIQ:
To show SpO
2
SIQ, follow this procedure:
1.
Select the SpO
2
numeric area or waveform area to enter the
SpO2
menu.
2.
Select the
Setup
tab.
3.
Switch on
Display SIQ
.
11.6.7
Changing the Sensitivity
The SpO
2
value displayed on the monitor screen is the average of data collected within a specific time. The
shorter the averaging time is, the quicker the monitor responds to changes in the patient’s oxygen saturation
level. Contrarily, the longer the averaging time is, the slower the monitor responds to changes in the patient’s
oxygen saturation level, but the SpO
2
measurement is more stable. For critically ill patients, selecting shorter
averaging time will help understanding the patient’s state.
To set the averaging time, follow this procedure:
1.
Select the SpO
2
numeric area or waveform area to enter the
SpO2
menu.
2.
Select the
SpO2 Setup
tab.
3.
Set
Averaging

2
module.

Monitoring SpO
2
and NIBP Simultaneously
When monitoring SpO
2
and NIBP on the same limb simultaneously, you can switch on
NIBP Simul
to lock the
SpO
2
alarm status until the NIBP measurement ends. If you switch off
NIBP Simul
, low perfusion caused by NIBP
measurement may lead to inaccurate SpO
2
readings and therefore cause false physiological alarms.
To set the
NIBP Simul
, follow this procedure:
1.
Select the SpO
2
numeric area or waveform area to enter the
SpO2
menu.
2.
Select the
Alarm
tab.
3.
Select
SpO2
tab.
4.
Set

Changing the Sweep Speed of the Pleth Wave
To set the sweep speed of Pleth waveforms, follow this procedure:
1.
Select the SpO
2
numeric area or waveform area to enter the
SpO2
menu.
2.
Select the
SpO2 Setup
tab.
3.
