after prolonged application.
Extremities to Avoid: Avoid sites distal to NBP cuff, intra-arterial line,
or intravascular venous infusion line.
Follow the SpO
sensor's Instructions for Use, adhering to all warnings
If necessary, remove colored nail polish from the application site.
Apply the sensor to the patient. The application site should match the
sensor size so that the sensor can neither fall off, nor apply excessive
Check that the light emitter and the photodetector are directly opposite
each other. All light from the emitter must pass through the patient's
The sensor cable is either directly connected to the blue SpO
the MX40 patient cable or is connected to an adapter cable that is then
connected to the MX40 SpO
The pulse signal tone is controlled by the setting in the SpO
Note — Tone Modulation Indication is only available when operating in
Continuous mode. It is not available when operating in Manual or Auto

which gives an indication of the reliability of the current values.
The level to which the triangle is filled shows the quality of the signal. The
signal quality is at a maximum when the triangle is completely filled.
