Sensor Performance Considerations

6.3.3

WARNING:
Pulse oximetry readings and pulse signal can be affected by certain ambient
conditions, sensor application errors, and certain patient conditions.

WARNING:
Tissue damage can be caused by incorrect application or inappropriate
duration of use of a pulse oximetry sensor. Inspect the sensor site as directed
in the Directions for Use.

WARNING:
Use only Covidien-approved pulse oximetry sensors and pulse oximetry
cables when connecting to the sensor connector. Connecting any other cable
or sensor influences the accuracy of sensor data, since this may lead to
adverse results.

WARNING:
Failure to cover the pulse oximetry sensor site with opaque material in high
ambient light conditions may result in inaccurate measurements.
Inaccurate Sensor Measurement Conditions
A variety of conditions can cause inaccurate Nellcor™ pulse oximetry sensor
measurements.
Incorrect application of the pulse oximetry sensor
•
Placement of the pulse oximetry sensor on an extremity with a blood pressure cuff,
•
arterial catheter, or intravascular line
Ambient light
•
Failure to cover the pulse oximetry sensor site with opaque material in high ambient
•
light conditions
Excessive patient activity
•
Dark skin pigment
•
Intravascular dyes or externally applied coloring, such as nail polish or pigmented
•
cream
