SENSOR OFF PATIENT — CHECK CONNECTION AT PATIENT
•
The module does not detect a valid sensor input signal. Check
the patient for proper sensor placement.
•
The tissue between the LED and photodiode is too transmissive.
If the sensor placement seems correct and the message persists,
try a sensor site with a thicker tissue bed.
Note:
This message is not available with disposable SpO
2
sensors or
non-clip type sensors.
FAULTY SENSOR — REPLACE SENSOR
•
The LED and/or photodiode have failed. Replace the sensor.
AMBIENT LIGHT INTERFERENCE — COVER SENSOR AREA
•
The sensor is receiving external light interference from a bright
light source near the sensor. Shield the sensor from the external
light source.
•
The sensor photodiode and LEDs are misaligned on flexible
sensors thereby allowing light to enter. Realign the sensor
photodiode with LEDs.
•
If the message persists, replace the sensor.
INSUFFICIENT SIGNAL — REPOSITION OR REPLACE SENSOR
•
Insufficient signal for proper operation as evidenced by a low
deflection on Sensorwatch signal strength bar.
•
Poor sensor application or site. Correctly re-apply or reposition
to a better perfused site or massage site.
•
If the message persists, replace the sensor.
NOISY SIGNAL
•
Sensor signal disturbed by motion or other interference.
Eliminate sensor movement. Message disappears when the value
is obtained.
•
Sensor placement adjacent to power cords or other electrically
noisy devices. Move the noisy device or move the sensor to
another site.
•
If the message persists, replace the sensor.
NIBP Alarm Message Summary
The 90217 ABP monitor provides an extensive set of result codes
that indicate the status of the monitor and the potential causes of an
inability to take a valid reading.
