8.6.4 Setting SpO
2
Sensitivity (for Masimo SpO
2
)
For Masimo SpO
2
, selects the Sensitivity as per signal quality and patient motion.
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 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. 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.
•
Changing workflows 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.
8.6.5 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.
