Next Steps
SpHb reading is dim
and "Low SpHb SIQ"
message displays
Improper sensor
application.
Excessive motion.
Low perfusion.
Verify and re-apply sensor. See
Directions for Use for sensor.
Check and see if blood flow to
the 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.
Submit blood sample for
laboratory CO-Oximetry test
for comparison.
Check patient conditions
indicated to affect SpHb
accuracy.
Unexpected
Parameter Readings
Low SIQ or Pi values.
Inappropriate sensor
size or sensor
measurement location.
Excessive motion.
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.
Minimize or eliminate motion
at the monitoring site.
Unable to export
SpHb data
Poor connection to
network.
Incorrect network
configuration.
Cable is not fully seated
in device.
Baud rate does not
match between device
and data download
application. See
