Accuracy can be affected by incorrect sensor application or
use; intravascular dyes; bright light; excessive patient
movement; venous pulsations; electrosurgical interference;
and placement of a sensor on an extremity that has a blood
pressure
cuff, arterial catheter, or intravascular line.
SOLUTION:
l
Check that calculations have been corrected appropriately for
the relevant variable. In general, calculated saturation values
are not as reliable as direct laboratory hemoximeter
measurements.
l
If
there is excessive light, cover the sensor with opaque
material.
l
Circulation distal to the sensor site should be checked
routinely. The site must be inspected every
8 hours to ensure
adhesion, skin integrity, and
correct optical alignment. If skin
integrity changes, move the sensor to another site.

Sp02 calculation may not have correctly adjusted for the
effects of
OXISENSOR N-25 oxygen transducer to an appropriate
site. This sensor has added protection against electrosurgical
interference.
PROBLEM: The oxygen saturation measurement does not
correlate with the value calculated from a blood gas
determination.

Plug the Monitor and the
ESU into different AC circuits.

Move the ESU ground pad as close to the surgical site as
possible.
