especially sunlight. Shield the sensor area if necessary.
Dyes introduced into the bloodstream, such as methylene
blue, indocyanine green, indigo carmine, and fluorescein,
may influence the accuracy of the SpO
2
reading.
Any condition that restricts blood flow, such as use of a blood
pressure cuff or extremes in systemic vascular resistance,
may cause a failure to determine accurate pulse rate and
SpO
2
readings.
Remove fingernail polish or artificial fingernails before
applying SpO
2
sensors. Fingernail polish or artificial
fingernails may cause inaccurate SpO
2
readings.
Optical cross-talk can occur when two or more sensors are
located in adjoining areas. It can be eliminated by covering
each site with opaque material. Optical cross-talk may
adversely affect the accuracy of the SpO
2
readings.
Obstructions or dirt on the sensor’s red light or detector may
cause a sensor failure. Make sure there are no obstructions
and the sensor is clean.
For routine equipment maintenance, please refer to the
service procedures at the associated section as indicated in
the manual.
As to the other concerns for attention, please carefully look
through the specific chapter in this instruction.
