SpO2 Monitoring 7-3
At elevated ambient temperatures, be careful with measurement sites
that are not well perfused, because this can cause severe burns after
prolonged application. All listed sensors operate without risk of
exceeding 41
o
C on the skin if the initial skin temperature does not
exceed 37
o
C.
Avoid placing the sensor on extremities with an arterial catheter or
intravascular venous infusion line.
Sensors connected to the MX40 but not applied to the patient, can
produce an error measurement. To avoid misdiagnosis, ensure the
sensor is properly applied to the patient.
Cautions
If you measure SpO2 on a limb that has a inflated NBP cuff, a
non-pulsatile SpO2 INOP (SpO2T NO PULSE) can occur. If the monitor
is configured to suppress this alarm, there may be a delay of up to 60
seconds in indicating critical patient status, such as sudden pulse loss or
hypoxia.
Do not use OxiCliq disposable sensors in a high humidity environment,
such as an incubator, or in the presence of fluids, which may
contaminate sensor and electrical connections causing unreliable or
intermittent measurements. Do not use disposable sensors on patients
who have allergic reactions to the adhesive.
Do not use more than one extension cable (M1941A). See Appendix A,
Accessories, for information on which sensors cannot be used with an
extension cable.
Position the sensor cable away from power cables to avoid electrical
interference.

Information for the User
The pulse oximeter is calibrated to indicate functional oxygen saturation
(fractional oxyhemoglobin), and displayed results can range from 0 to
100%.
A 10 second averaging filter is used in the calculation of the result.
Displayed results are typically updated every second, but the update
period can be automatically delayed by up to 30 seconds in the presence of
noise.
