11.6.6 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 for Masimo SpO
2
module, and Sensitivity for Mindray SpO
2
module.
11.6.8 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
NIBP Simul.
11.6.9 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. Set
Speed.
11.6.10 Setting the Alarm Priority for SpO
2
Sensor Off Alarm
To set the alarm level for SpO
2
sensor off alarm, follow this procedure:
1. Select the
Main Menu quick key → from the System column select Maintenance → input the required
password
→ select .
2. Select the
Alarm tab → select the Other tab.
