The SpO
2
measurement is unstable.
Cause 1 : There is excessive body motion of the patient which disables correct
measurement.
Solution : 1. Have the patient lie as still as possible.
2. Relocate the sensor, or change the sensor position where body
motion will have less influence.
Cause 2 : The probe size is inadequate.
Solution : Select a probe size which is appropriate for the patient.
Cause 3 : Sensor is exposed to light.
Solution : Place a black or dark cloth over the sensor to avoid direct sunlight.
The <SpO
2
Disconnected> message is displayed.
Cause : When the SpO
2
relay cable is disconnected during SpO
2
monitoring,
this message will be displayed.
Solution 1 : To cease monitoring, press the [Alarm Silence] key. This will clear
the message and silence the alarm.
Solution 2 : To continue monitoring, plug in the SpO
2
relay cable. This will clear
the message and silence the alarm.
The <SpO
2
Sensor Fault> message is displayed.
Cause 1 : The sensor is not connected securely.
Solution :
Reattach the sensor.
Cause 2 : The sensor is defective.
Solution : Replace the sensor.
Cause 3 : A wrong sensor is used.
Solution : Replace the sensor.
The <SpO
2
Check Sensor> message is displayed.
Cause 1 : Unrecognizable sensor or a wrong sensor may be connected.
Cause 2 : When attached to the patient, the sensor was exposed to
high-intensity light which lead to false recognition.
Solution : Reattach the sensor and patient cable.
Replace with a Fukuda Denshi specified patient cable and sensor.
The <SpO
2
Pulse Search> message is displayed.
Cause 1 : The amplitude of the pulse waveform is too low, or the sensor is not
positioned correctly.
Solution : Check if the light emitting and receiving parts of the sensor LED are
aligned.
Cause 2 : The sensor has not been attached long enough to obtain stable
measurement.
Solution : After the sensor attachment, wait for about one minute to see if the
waveform stabilizes.
