Sensor Performance Considerations

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
Instructions
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 mea-
surements.

Incorrect application of the pulse oximetry sensor
•
Placement of the pulse oximetry sensor on an extremity with a blood pressure cuff, arte-
rial catheter, or intravascular line
•
Ambient light
•
Failure to cover the pulse oximetry sensor site with opaque material in high ambient light
conditions
•
Excessive patient movement
