Next Steps
Difficulty obtaining
a reading
Inappropriate sensor or
sensor size.
Improper sensor type or
application.
Low perfusion.
Excessive motion
artifact.
Excessive ambient or
strobing light.
Interference from line
frequency-induced
noise.
Allow time for parameter
reading to stabilize.
Verify sensor type and size and
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.
Verify the device and sensor
are configured with the
parameter.
Verify proper sensor and
sensor size for the patient.
Shield the sensor from
excessive or strobing light.
Minimize or eliminate motion
at the measurement site.
Verify and set 50 or 60Hz
menu setting. See
Localization
on page 48.
