10.5.2. Setting Sensitivity
The SpO2 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 SpO2 measurement is more stable. 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 SpO2 parameter area or waveform area to enter the【SpO2】menu.
2. Select【SpO2
Setup】submenu.
3. Select【Sensitivity】and then toggle between【High】,【Med】or【Low】.
10.5.3. Setting NIBP measurement on the same limb
When monitoring SpO2 and NIBP on the same limb simultaneously, you can switch
on 【NIBP Simul】 to lock the SpO2 alarm status until the NIBP measurement ends. If
you switch off 【NIBP Simul】, low perfusion caused by NIBP measurement may lead to
inaccurate SpO2 readings and therefore cause false physiological alarms.
To set the 【NIBP Simul】, follow this procedure:
1. Select the SpO2 parameter area or waveform area to enter the【SpO2】menu.
2. Select【Alarm】submenu.
3. Set【NIBP Simul】as to【On】or【Off】.
10.5.4. Changing the Speed of Pleth Waveform
To set the sweep speed of Pleth waveforms, follow this procedure:
1. Select the SpO2 parameter area or waveform area to enter the【SpO2】menu.
2. Select 【SpO2 Setup】 submenu.
3. Set 【Wave Speed】 to the appropriate value. The larger the value, the faster
the scanning speed and the wider the waveform.
10.5.5. Setting Pitch Tone
The pitch tone function is on by default. The steps to turn off the pitch tone function
