11.8.7 Set Average Time (Not for Nellcor 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. Similarly,
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.
11.8.7.1 Average Time for Masimo SpO

1) Select the SpO
2
parameter area or waveform area to enter [SpO
2
] menu.
2) Select [SpO
2
Setup] tab.
3) Set [Average Time] to [2-4], [4-6], [8], [10], [12], [14] or [16], the unit is s.

parameter area or waveform area to enter [SpO
2
] menu.
2) Select [SpO
2
Setup] tab.
3) Set [Sensitivity] to [High], [Med] or [Low], and the corresponding average time will increase accordingly.
11.8.8 Set Fast Sat (for Masimo SpO
2
Only)
FastSat (fast saturation) enables rapid response to, and display of, fast changes in %SpO
2.
For the 2 and 4 second
settings the averaging time may range from 2-4 and 4-6 seconds, respectively, by giving priority to the most recent
data. This aids the clinician in clinical settings requiring fast response time such as those seen with induction,
intubation, sleep studies and resuscitation. When set to on, the [FastSat] is indicated on the display.
1) Select the SpO
2
parameter area or waveform area to enter [SpO
2
] menu.
2) Select [Setup] tab.
3) Turn [Fast Sat.] on or off.
11.8.9 Set Smart Tone (For Masimo SpO
2
Only)
When smart tone is set to on the QRS volume would still be heard in case of an unstable signal or ambient noise.
