Performance Considerations
6-4
Operator’s Manual
Signal Loss
Loss-of-pulse signal can occur for several reasons.
•
Pulse oximetry sensor applied too tightly
•
Inflation of a blood pressure cuff on the same extremity as the attached pulse oximetry
sensor
•
Arterial occlusion proximal to the pulse oximetry sensor
•
Poor peripheral perfusion
Recommended Usage
Select an appropriate Nellcor™ pulse oximetry sensor, apply it as directed, and
observe all warnings and cautions presented in the
Instructions for Use
accompany-
ing the sensor. Clean and remove any substances such as nail polish from the appli-
cation site. Periodically check to ensure that the sensor remains properly positioned
on the patient.
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 a Nellcor™ pulse oximetry sensor. To
prevent interference from ambient light, ensure that the sensor is properly applied,
and cover the sensor site with opaque material.
If patient movement presents a problem, try one or more of the following remedies to
correct the problem.
•
Verify the Nellcor™ pulse oximetry sensor is properly and securely applied.
•
Move the sensor to a less active site.
•
Use an adhesive sensor that improves patient skin contact.
•
Use a new sensor with fresh adhesive backing.
•
Keep the patient still, if possible.
If poor perfusion affects performance, consider using the Nellcor™ forehead SpO
2
sensor (MAXFAST).
