Maximum sensitivity is recommended for use on patients with weak signals (e.g. high ambient noise and/or
patients with very low perfusion) and for use during procedures or when clinician and patient contact is
continuous such as in higher acuity settings.
To set SpO
2
sensitivity, 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
Sensitivity
to
Maximum, Normal, or APOD
.
CAUTION
•
When using the Maximum Sensitivity setting, performance of “Sensor Off” detection may be
compromised. If the equipment and the sensor becomes detached from the patient, the potential
for false readings may occur due to environmental noise such as light, and vibration.
•
Configuring the monitor to “Load Latest Configuration” as the default configuration may result in
Masimo SpO
2
being set to Maximum sensitivity mode on power up or after admitting a new patient.
Maximum sensitivity is recommended for use during procedures or when clinician and patient
contact is continuous, such as in higher acuity settings. Maximum sensitivity is not recommended
for care areas where patients are not monitored visually as “Sensor Off” detection may be
compromised. Refer to
Section 6.4 Setting Default Configuration
for managing configuration.
13.6.5 Enabling FastSAT (for Masimo SpO
2
)
FastSAT enables rapid tracking of arterial oxygen saturation changes as may be required in urgent situations.
When FastSAT is switched on, the averaging algorithm evaluates all the SpO
2
values and provides an averaged
SpO
2
value that is a better representation of the patient’s current oxygen saturation status.
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. Select the SpO
2
numeric area or waveform area to enter the
SpO2
menu.
2. Select the
Setup
tab.
3. Switch on
FastSAT
.
13.6.6 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
.
13.6.7 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.
