VS 8/VS 8A Vital Signs Monitor Operator’s Manual 6 - 9
Normal sensitivity is the recommended for patients who are experiencing some
compromise in blood flow or perfusion. It is advisable for care areas where patients are
observed frequently, such as the intensive care unit (ICU).
Adaptive Probe Off Detection (APOD) sensitivity is the recommended sensitivity mode
where there is a high probability of the sensor becoming detached. It is also the
suggested mode for care areas where patients are not visually monitored continuously.
This mode delivers enhanced protection against erroneous pulse rate and arterial
oxygen saturation readings when a sensor becomes inadvertently detached from a
patient due to excessive movement.
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. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 dialog. In Spot Check mode, select the Main Menu quick key
→ from the Parameters column select Setup → select SpO2.
2. Select the 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 SpO2 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.
6.6.5 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. In Continuous Monitoring mode, select the SpO
2
numeric area or waveform area
to enter the SpO2 dialog. 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.
6.6.6 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 dialog. 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.
6.6.7 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 dialog. In Spot Check mode, select the Main Menu quick key
→ from the Parameters column select Setup → select SpO2.
2. Select the Setup tab.
3. Set Averaging.
