11.4.4 Monitoring SpO
2
 and NIBP Simultaneously 
When monitoring SpO
2
 and NIBP on the same limb simultaneously, you can switch [NIBP 
Simul] on in the [SpO
2
 Setup] menu to lock the SpO
2
 alarm status until the NIBP 
measurement ends. If you switch [NIBP Simul] off, low perfusion caused by NIBP 
measurement may lead to inaccurate SpO
2
 readings and therefore cause false physiological 
alarms. 
 
 
11.4.5 Changing the Speed of the Pleth Wave 
In the [SpO
2
 Setup] menu, select [Sweep] and then select the appropriate setting. The faster 
the waveform sweeps, the wider the waveform is.

For Mindray SpO2 module, you can display PI value in larger characters for better view. To 
zoom in the display of PI value, set [PI Zoom] to [Yes] from the [SpO2 Setup] menu.
