Precautions for Use 

Warnings 

• 

The Model 8500AV Pulse Oximeter is intended for VETERINARY USE ONLY.  Do not use on human patients. 

• 

Accurate oxygen saturation measurement cannot be obtained when the oximeter is not measuring the pulse properly.  
If the Perfusion LED is erratic or the Pulse Rate display is erratic or inaccurate, first examine the animal for any 
signs of distress and only then reexamine sensor placement. 

• 

Do not operate in an explosive atmosphere. 

• 

Inadequate perfusion, thick fur, foreign matter that blocks light, or an improperly applied sensor can result in erratic 
and inaccurate oxygen saturation and/or pulse rate measurement.  Follow the instructions outlined in “Verify 
Operation.”  If proper operation cannot be verified, remove the sensor from the animal and DO NOT use the 
oximeter on this animal. 

• 

In the event the sensor becomes dislodged from the animal, audible and visual alarms are activated, requiring that a 
veterinary professional investigate the reason for the alarm status. The veterinary  professional must investigate 
animal status and sensor attachment after every sensor alarm indication. It is possible when the sensor is dislodged 
from the animal (under certain conditions of light and vibration of the sensor) for the pulse oximeter to display 
normal physiological values.  

• 

NONIN does not recommend operating the Model 8500AV in an MRI environment. 

• 

Do not remove any covers other than the battery cover when battery replacement is necessary.  There are no user 
serviceable parts inside other than the replaceable batteries.  Refer service to qualified NONIN personnel. 

• 

Operation of this device below the minimum amplitude of 0.5% modulation may cause inaccurate results.  

• 

This device should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, 
the device should be observed carefully to verify normal operation. 

• 

The use of accessories, sensors, and cables other than those listed in this manual may result in increased emission 
and/or decreased immunity of this device. 

Cautions 

• 

Read this manual carefully before using the Model 8500AV Pulse Oximeter. 

• 

USE ONLY NONIN VETERINARY SENSORS. 

• 

Use only NONIN compatible accessories and veterinary sensors to preserve the integrity and accuracy of the 
monitor. 

• 

Cardiogreen and other intravascular dyes, depending on concentration, could affect the accuracy of the 
measurement. 

• 

The Model 8500AV Pulse Oximeter is calibrated to determine the percentage of arterial oxygen saturation of 
functional hemoglobin measured at the finger tip of an adult human. Significant levels of dysfunctional 
hemoglobins such as carboxyhemoglobin or methemoglobin might affect the accuracy of the measurement. Other 
types of hemoglobin and alternate sensor locations may affect the calibration. 

• 

Certain pharmacologic agents used to sedate or anesthetize animals may have cardiovascular effects that can 
adversely affect the performance of the pulse oximeter by reducing the perfusion to the sensor site. Examples of 
commonly used agents that may have this type of effect on certain animal species are Detomidine HCl and 
Xylazine HCl. 

• 

There is a wide range of variability between animal species and their respective differences in anatomy, physiology 
and responses to veterinary pharmacological agents. Therefore, the veterinarian will need to use discretion when 
selecting sensors and/or sensor sites that are appropriate for the animal species and the monitoring conditions. 

• 

When attaching the sensor, make sure not to secure the sensor in a manner that will restrict perfusion. This could 
inhibit proper function of the oximeter and cause discomfort or localized ischemia to the animal.   

• 

If the sensor is not positioned on a perfused site, or at least ten seconds of green perfusion pulses cannot be 
observed for a given sensor, change sensor location or sensor type until this condition is achieved.
