Pulse Oximetry Measurement
9-8 SpO2 Monitoring
 Ambient Temperature: Never apply an SpO2 sensor at ambient
temperatures above 37
o
C (99
o
F) because this can cause severe burns
after prolonged application.
 Extremities to Avoid: Avoid sites distal to NBP cuff, intra-arterial line,
or intravascular venous infusion line.
Applying the Sensor
1 Follow the SpO2 sensor's Instructions for Use, adhering to all warnings
and cautions.
2 If necessary, remove colored nail polish from the application site.
3 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
pressure.
4 Check that the light emitter and the photodetector are directly opposite
each other. All light from the emitter must pass through the patient's
tissue.
Connecting SpO
2
Cables
The sensor cable is either directly connected to the blue SpO2 connector on
the MX40 patient cable or is connected to an adapter cable that is then
connected to the MX40 SpO2 connector.
Tone Modulation Indication
The pulse signal tone is controlled by the setting in the SpO
2
Tone
Modulation menu.
Note — Tone Modulation Indication is only available when operating in
Continuous mode. It is not available when operating in Manual or Auto
mode.
Signal Quality Indicator
The SpO2 numeric is displayed together with a signal quality indicator
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.
