The reliability of FastSAT is dependent on the setting for the averaging time and the
input signal. FastSAT is disabled by default. To enable FastSAT, follow this procedure:
1. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 menu. In Spot Check mode, select the Main Menu quick key →
from the Parameters column select Setup → select SpO2.
2. Select the Setup tab.
3. Switch on Fast SAT.
8.6.6 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. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 menu. In Spot Check mode, select the Main Menu quick key →
from the Parameters column select Setup → select SpO2.
2. Select the Setuptab.
3. Switch on Display SIQ.
8.6.7 Changing Averaging Time (for Masimo SpO
2
)
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 a
shorter averaging time will help with understanding the patient’s state.
To set the averaging time, follow this procedure:
1. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 menu. In Spot Check mode, select the Main Menu quick key →
from the Parameters column select Setup → select SpO2.
2. Select the Setup tab.
