Troubleshooting Guide

Problem
Numeric displays are
blinking once per second
Displayed pulse rate does
not correlate to pulse rate
displayed on ECG
monitor
Erratic ♥ display and/or
yellow perfusion indicator
during concurrent use of
electrosurgical equipment
or ultrasonic dental scalers
Perfusion is blinking
yellow with each pulse
Perfusion indicator is
blinking red and SpO and
2
♥ displays show dashes
or ♥
Segments of SpO
2
display are missing
Unable to obtain green
perfusion
Alarm going continuously
but SpO and pulse rate
2
are within alarm limits
If any of these solutions do not correct the problem with your Model 8600V, please contact NONIN Customer
Support at (800) 356-8874 (USA and Canada) or (763) 553-9968.
Possible Cause
SpO or pulse rate alarm condition
2
exists
Excessive motion at sensor site may
be prohibiting the 8600V from
acquiring a consistent pulse signal
Animal may have an arrhythmia
resulting in some heart beats that do
not yield a perfusion signal at sensor
sight
Non-NONIN sensor is being used
ECG monitor may not be
functioning properly
ESU or ultrasonic dental scaler may
be interfering with oximeter
performance
Perfusion signal at sensor site is
marginal
Inadequate perfusion signal at sensor
site
Excessive motion at sensor site may
be prohibiting 8600V from acquiring
a consistent pulse signal
Defective LED displays
Low animal pulse strength
Sensor site poorly perfused
Sensor not correctly positioned
Sensor attached too tightly or tape
or other items are restricting
perfusion at sensor site
Circulation reduced due to excess
pressure between the sensor and a
hard surface.
Excessive ambient light
Excessive animal motion
Interference from:
• arterial catheter
• blood pressure cuff
• electrosurgical procedure
• infusion line
Internal circuitry watchdog failed
Possible Solution
Examine the patient:
animal may need medical attention
Eliminate or reduce cause of motion artifact or
reposition sensor to new sensor site where
motion is not present
Examine the animal:
condition may persist even though both monitors
are functioning properly if animal's arrhythmia
persists
Replace sensor with a NONIN sensor
Examine the animal:
replace ECG monitor or refer to operator's
manual for ECG monitor
Examine the animal:
move oximeter, cables, and sensor as far away
from ESU or ultrasonic dental scaler as possible
or refer to the ESU operator's manual
Examine the animal:
reposition sensor or select alternate sensor site
Examine the animal:
reposition sensor or select alternate sensor site
Eliminate or reduce cause of motion artifact or
reposition sensor to sensor site where motion is
not present
Displayed values may not be reliable; discontinue
use of 8600V
Reposition sensor on animal
Reapply sensor, select alternate sensor site, or
remove restrictive material from sensor site
Allow applied sensor to rest comfortably on a
soft surface
Reduce ambient light
Reduce animal motion
Reduce or eliminate interference
Reset 8600V by turning the unit OFF, wait a few
seconds, and turn the unit ON
