CAUTION
•
Change the application site or replace the sensor and/or patient cable when a
persistent SpO2 Low Signal Quality message is displayed on the equipment.
These messages may indicate that patient monitoring time is exhausted on
the patient cable or sensor.
•
Replace the cable or sensor when a “SpO2 Sensor Off”, “SpO2 No Sensor”, or
“SpO2 Low Signal Quality” message is consistently displayed while
monitoring consecutive patients after completing troubleshooting steps
listed in this manual.
•
Variation in measurements may be profound and may be affected by
sampling technique as well as the patient's physiological conditions. Any
results exhibiting inconsistency with the patient’s clinical status should be
repeated and/or supplemented with additional test data. Blood samples
should be analyzed by laboratory instruments prior to clinical decision
making to completely understand the patient’s condition.
•
Use only SpO
2
sensors specified in this manual. Follow the SpO
2
sensor’s
instructions for use and adhere to all warnings and cautions.
•
Do not place the pulse oximeter where the controls can be changed by the
patient.
•
If using patient monitor during full body irradiation, keep the sensor out of
the radiation field. If the sensor is exposed to the radiation, the reading
might be inaccurate or the device might read zero for the duration of the
active irradiation period.
NOTE
•
Additional information specific to the Masimo sensors compatible with the
equipment, including information about parameter/measurement
performance during motion and low perfusion, may be found in the sensor's
directions for use (DFU).
•
Masimo cables and sensors are provided with X-Cal™ technology to minimize
the risk of inaccurate readings and unanticipated loss of patient monitoring.
Refer to the Cable or Sensor DFU for the specified duration of the patient
monitoring time.
