13 - 7
To set the averaging time, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 menu.
2. Select the SpO2 Setup tab.
3. Set Averaging.
13.6.8 Changing Sensitivity (for Mindray 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 shorter
averaging time will help understanding the patient’s state.
To set the averaging time, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 menu.
2. Select the SpO2 Setup tab.
3. Select Sensitivity, and then toggle between High, Med and Low, which respectively correspond to 7 s, 9 s
and 11 s.
13.6.9 Showing/Hiding PI
You can set whether to display PI in the SpO
2
parameter area. To do so, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 menu.
1. Select the Setup tab.
2. Switch on or off Display PI.
13.6.10 Monitoring SpO
2
and NIBP Simultaneously
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
numeric area or waveform area to enter the SpO2 menu.
2. Select the Alarm tab.
3. Select SpO2 tab.
4. Set NIBP Simul.
13.6.11 Changing the Sweep Speed of the Pleth Wave
To set the sweep speed of Pleth waveform, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 menu.
2. Select the SpO2 Setup tab.
3. Set Speed.
13.7 Changing the PR Settings
13.7.1 Changing the PR Alarm Settings
To change the PR alarm settings, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 menu.
2. Select the PR Alarm tab.
3. Enter the password if required.
