1. Select the SpO
2
parameter area or waveform area to enter the【SpO

】menu.
2. Select【SpO
2
Setup】submenu.
3. Select【Sensitivity】and then toggle between【High】,【Med】or【Low】.
10.7.5. Setting Averaging Time (Only for Masimo SpO
2
and 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, the quicker the monitor responds to
changes in the patient’s oxygen saturation level, but the lower the measurement accuracy.
Contrarily, the longer the averaging time, the slower the monitor responds to changes in
the patient’s oxygen saturation level, but the higher the measurement accuracy. For
critically ill patients, selecting shorter averaging time will help understanding the patient’s
state.
To set the averaging time, follow this procedure:
1. Select the SpO
2
L parameter area or waveform area to enter the【SpO
2
L】menu.
2. Select【SpO
2
LSetup】submenu.
3. Set the【Averaging Time】.
10.7.6. Setting NIBP measurement on the same limb
When monitoring SpO
2
and NIBP on the same limb simultaneously, you can switch
on 【NIBP Simul】 to lock the SpO
2
alarm status until the NIBP measurement ends. If
you switch off 【NIBP Simul】, low perfusion caused by NIBP measurement may lead to
inaccurate SpO
2
readings and therefore cause false physiological alarms.
To set the 【NIBP Simul】, follow this procedure:
1. Select the SpO
2
parameter area or waveform area to enter the【SpO
2
】menu.
2. Select【Alarm】submenu.
3. Set【NIBP Simul】as to【On】or【Off】.
10.7.7. Changing the Speed of Pleth Waveform
To set the sweep speed of Pleth waveforms, follow this procedure:
1. Select the SpO
2
parameter area or waveform area to enter the【SpO
2
】menu.
2. Select 【SpO
2
Setup】 submenu.
