Sensors and Accessories

Inaccurate measurements can be caused by:

• incorrect application of the sensor

• placement of the sensor on an extremity with a blood

pressure cuff, arterial catheter, or intravascular line

• ambient light

• patient movement

• Loss of pulse signal can occur for the following reasons:

• the sensor is too tight

• a blood pressure cuff is inflated on the same extremity as

the one with the sensor attached

• there is arterial occlusion proximal to the sensor

Use only Nellcor sensors and sensor cables. Select an appropriate

sensor, apply it as directed, and observe all warnings and cautions

presented in the directions for use accompanying the sensor.

Clean and remove any substances such as nail polish from the

application site. Periodically check to see that the sensor remains

properly positioned on the patient.

WARNING: Tissue damage can be caused by incorrect

application or duration of use of an SpO2 sensor. Inspect the

sensor site as directed in the sensor directions for use.

High ambient light sources such as surgical lights (especially

those with a xenon light source), bilirubin lamps, fluorescent

lights, infrared heating lamps, and direct sunlight can interfere

with the performance of an SpO

2 sensor. To prevent interference

from ambient light, ensure that the sensor is properly applied, and

cover the sensor site with opaque material.

Note: Failure to take this precaution in high ambient light

conditions may result in inaccurate measurements.

If patient movement presents a problem, try one or more of the

following remedies to correct the problem.

• Verify that the sensor is properly and securely applied.

• Move the sensor to a less active site.

• Use an adhesive sensor that tolerates some patient motion.
