re-apply sensor. See Directions for
Use for sensor.
• Check if blood flow to the sensor
site is restricted.
• Check the placement of the
sensor. Re-apply sensor or move
to a different site.
• Replace sensor.
• Minimize or eliminate motion at
the monitoring site.
• Set to MAX Sensitivity. See

Parameter Values Do Not
Correlate With Clinical
Assessment or Arterial
Blood Gas
Measurements
• Low perfusion.
• Sensor
displacement.
• Check for error messages. See
Chapter 13: Alarms and Messages
on page 153.
• Check placement of sensor or if it
is too tight. Reapply sensor or
select a new site. Set to MAX

patient. See Directions for Use for
sensor.
Unexpected Parameter
Readings
• Low SIQ or Pi
values.
• Inappropriate
sensor size or
sensor
measurement
location.
• Reposition sensor to site with
strong SIQ and Pi. Average
readings taken from three
different sites to improve
accuracy. Submit blood sample for
laboratory CO-Oximetry test for
comparison.
• Verify proper sensor for patient
size. Verify proper sensor site. See
Directions for Use for sensor.
