Dashes are displayed for
measurement.
and/or
Four or fewer pleth bar
segments pulsate.
Poor signal quality due to a
disconnected sensor, poor sensor
placement, low perfusion, or
interference, for example.
The pulse strength is considered low
when only the lower four pleth bar
segments pulsate.
NOTE: When this condition is
caused by disconnection of the
sensor from the monitor or patient,
pressing the Alarm Silence button
once will cancel the alarm.
Connect the sensor to the monitor.
Apply the sensor as directed in the
instructions for the sensor.
• Make sure the sensor detector is
completely covered by the patient’s skin
and is directly opposite the light source.
• Remove debris from the sensor detector
and light source.
• If the site is thick, select a site where
there is less distance between the light
source and the detector.
• (Ear) Gently massage the sensor site to
increase perfusion.
• (Finger or Toe) Remove polish and
artificial fingernails; clip long nails.
Remove sources of interference, such as an
electrosurgical device or excessive ambient
light.
Change the sensor site or use a different
style of sensor.
Dashes are displayed for
measurement.
Signal interference due to incorrect
line power filter setting, poor
grounding at the AC power source,
or adjacent sensors (two or more
SpO
2
sensors on the same hand or
foot, for example).
Continuous, severe motion.
• Change the line power filter setting. See
Changing the line power filter in
chapter 2.
• Use battery power or use a grounded
AC power source for the monitor,
printer, and/or PC.
• Apply only one sensor to the hand, foot,
or other site.
Calm the patient, change the sensor site, or
use a different style of sensor.
Faulty or incompatible sensor.
NOTE: An error number appears in
the high SpO
2
alarm limit area.
Replace the sensor. Use only
sensors. If the message reappears, note the
error number and contact authorized
service personnel.
Internal malfunction.
NOTE: An error number appears in
the high SpO
2
alarm limit area.
Power OFF, then ON again. If the message
reappears, note the error number and
contact authorized service personnel.
