Applying the Sensor
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
Tone Modulation Indication
The pulse signal tone is controlled by the setting in the SpO
Signal Quality Indicator
which gives an indication of the reliability of the current values.
Venous Pulsation: Do not apply sensor too tightly as this results in
venous pulsation, which can severely obstruct circulation and lead to
Ambient Temperature: Never apply an SpO
temperatures above 37
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
