Why are %SpO and heart not displaying on Nonin WristOx2 3150?
- MMelissa TownsendSep 23, 2025
If the %SpO indicator and the heart in the pulse strength indicator do not display on your Nonin Medical Equipment, use nVISION software to configure the device to full or partial display mode, because the device has been set to Memory Volume (MVI) display mode.
