Problem
Pulse Quality indicator does
not blink green.
The Pulse Quality indicator
blinks red and the SpO
or pulse rate displays are
dashes.
Numeric display segments
are missing.
The lower CO bar is not lit.
2
Only the third and sixth CO
bars are lit.
Degradation of device
performance.

Possible Cause
Inadequate pulse signal
or
the sensor site is poorly perfused
or
the sensor is not correctly positioned.
Sensor is restricting blood circulation
at sensor site.
Circulation is reduced due to excess
pressure between the sensor and a
hard surface.
Excessive ambient light.
Excessive animal motion.
Performance degradation from:
• arterial catheter
• blood pressure cuff
• electrosurgical procedure
• infusion line
Inadequate pulse signal at sensor
and/ site.
2
Inadequate pulse signal due to
excessive motion.
SpO sensor failure.
2
Defective LEDs.
CO sensor is not plugged in.
2
CO sensor has become
2 2
disconnected.
Airway adapter tube is not connected
to the CO sensor.
2
Light path is blocked.
CO sensor lamp is burned out.
2
Electromagnetic interference (EMI).
Troubleshooting
Possible Solution
Reposition sensor.
Remove restriction to increase blood
circulation at sensor site or relocate
sensor.
Allow sensor and tongue/tissue to
rest comfortably on the surface.
Reduce ambient light.
Reduce animal motion.
Reduce or eliminate source.
Assess the animal. Reposition
sensor or select an alternate sensor
site.
Reduce animal motion. Reposition
or relocate sensor.
Replace SpO sensor.
2
Discontinue use of the device.
Plug CO sensor in.
2
Reconnect CO sensor.
2
Verify airway adapter tube is
connected, with windows toward the
sensor.
Replace airway adapter tube.
Replace CO sensor.
2
Remove device from the EMI
environment.
