Troubleshooting: Fetal Pulse Oximetry Troubleshooting
Sensor Lifted icon displayed in
FSpO
2 area of display.
 Sensor not making adequate contact at
the sensor site on the fetus.
 Damaged sensor.
 Assess sensor position relative to fetal
head. Assess sensor depth relative to
the fetal presenting part; advance or
withdraw the sensor as indicated in
“FSpO2 Status Icons” on page 5-20.
 If the icon does not respond to
advancing or withdrawing the sensor,
remove the sensor and place a new
sensor, as directed in “FSpO2 Status
Icons” on page 5-20.
Sensor Disconnected icon
displayed in FSpO
2 area of display.
 Sensor disconnected from fetal patient
module cable; or fetal patient module
cable disconnected from monitor.
 Damaged fetal patient module.
 Invalid FSpO2 sensor connected to fetal
patient module cable.
 Ensure fetal patient module cable is
firmly attached to sensor assembly and
monitor. If connections are OK, use a
new sensor.
 Replace with another Corometrics Fetal
Patient Module.
 Replace with valid Nellcor OxiFirst Fetal
Oxygen Sensor (Series FS14).
COMM message shown in FSpO2 area of
display.
 Communication error between the built-
in FSpO
2 module and the remainder of
the monitor circuitry.
 Contact Biomedical Engineering
Department.
FHR slows during, or immediately after,
sensor placement.
 Changes in intracranial pressure due to
examination could cause a reflex
bradycardia stimulus.
 Stop the exam. Do not proceed with
sensor placement. Wait for the FHR to
return to the previous range.
Dashes (– – –) shown in FSpO
2 display
area.
 Monitor unable to make a determination
due to insufficient signal.
 Improperly applied sensor.
 Excessive fetal movement.
 Excessive maternal movement.
 Maternal uterine contraction.
 Damaged sensor.
 SLOW mode selected.
 Check centimeter mark on stylet
chamber relative to the introitus. The
sensor may have ascended or
descended independent of fetal head
descent.
 Ensure that the fetal patient module
cable is firmly attached to the monitor
and to the sensor assembly.
 Move sensor to another location.
 Wait for movement to stop.
 Restrict patient movement.
 Wait for contraction to end.
 Replace sensor.
 Access FSpO2 Setup screen and select
FAST mode.
REPAIR message shown in FSpO2 display
area.
 System error or self-test failure.  Contact Biomedical Engineering
Department.
