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.

• The audible alarm of the Model 8500AV is for the convenience of the attendant near the patient. These units are
not intended to call an attendant from another room or from a distance. The user must determine the audible
distance based on the operating environment.
• Alkaline batteries must not be inserted improperly, charged, or disposed of in fire. They might leak or explode.
• This equipment complies with International Standard EN 60601-1-2:2001 for electromagnetic compatibility for
medical electrical equipment and/or systems. This standard is designed to provide reasonable protection against
harmful interference in a typical medical installation. However, because of the proliferation of radio-frequency
transmitting equipment and other sources of electrical noise in healthcare and other environments, it is possible
that high levels of such interference due to close proximity or strength of a source might disrupt the performance
of this device. Medical electrical equipment needs special precautions regarding EMC, and all equipment must be
installed and put into service according to the EMC information specified in this manual.
• This device has not been tested for immunity to electromagnetic disturbances.
• Portable and mobile RF communications equipment can affect medical electrical equipment.

Introduction
The NONIN 8500AV Veterinary Pulse Oximeter continuously monitors arterial hemoglobin oxygen saturation and
pulse rate. Its intended application is monitoring animals.
The Model 8500AV Oximeter is intended for spot-checking and displaying numerical values for arterial oxyhemoglobin
saturation and pulse rate.
The Model 8500AV Oximeter is small (3.0"W x 6"H x 1"D) and lightweight (10 oz. – 280 gm). It will typically operate
for 100 hours continuously between battery replacements.
The Model 8500AV determines arterial oxyhemoglobin saturation (%SpO
) by measuring the absorption of red and
2
infrared light passed through the tissue. Changes in light absorption caused by pulsation of blood in the vascular bed are
used to determine arterial saturation and pulse rate. The Model 8500AV requires no routine calibration or maintenance.
Oxygen saturation and heart rate are displayed on light emitting diode (LED) digital displays. On each detected pulse,
the perfusion LED flashes. Patient perfusion signals are graded as good, marginal, or inadequate and are indicated as
such by the LED changing color from green to yellow or red. This simple method gives the user a pulse by pulse visual
indication of waveform signal quality without requiring the user to perform complex waveform analysis during critical
patient care situations.
Sensor disconnect or malfunction is indicated by lack of good perfusion flashes and/or a minus (-) sign to the left of the
value on the LED display. Ultimately, if good perfusion pulses are not received, the SpO2 and Pulse Rate
SpO
2
numerical will be replaced by dashes. When the batteries are low, the digital displays will blink.

Veterinary Sensors
The Model 8500AV Oximeter features a sensor ideal for a variety of applications. These sensors include the Small
Lingual Clip (2000SL), the Small Animal Flex Sensor (2000SA), and the Transflectance Sensor (2000T). Each sensor is
designed for a specific site application and specific animal size. When selecting sensors for a particular application
consider the following:
1. The 2000SL Small Lingual Clip is recommended for spot checks or short term continuous monitoring. The
2000SL sensor performs best for most small animals when used on the tongue.
2. The 2000SA Small Animal Flex Sensor is suitable for use on the toe of a dog or on the paw or base of the tail
on very small animals such as rats.
3. The 2000T Transflectance sensor is for placement on the underside, base of the tail (near the anal orifice).
NONIN’s veterinary sensors are reusable. Clean them with an isopropyl alcohol wipe. Allow enough time for the
sensor to dry thoroughly before reusing.
CAUTION: Use only the NONIN Model 2000SL, 2000T, or 2000SA, Veterinary Sensors for monitoring. These
sensors are manufactured to meet the calibration requirements for the NONIN Model 8500AV Pulse
Oximeter. The oximeter is calibrated for adult human hemoglobin measured at the finger tip. Although
animal hemoglobin has similar optical characteristics, other types of hemoglobin or alternate sensor
locations may affect the calibration.
CAUTION: Each Nonin sensor is designed for a specific clinical application. Optimal performance can only be
attained by using each sensor appropriately.
Factors that can degrade performance:
• excessive ambient light
• excessive motion
• electrosurgical interference
• moisture in the sensor
• improperly attached sensor
• incorrect sensor for animal
• poor animal perfusion
• venous pulsations
• anemia or low hemoglobin concentrations
• cardiovascular dyes
• sensor not at heart level
CAUTION: Sensor sites must be checked periodically to determine circulation, sensor positioning and skin sensitivity.
NOTE: The Model 2000SL Small Lingual Clip, 2000T Transflectance, and 2000SA Small Animal Flex sensors differ
only in the configuration of the attachment housing. These sensor configurations enable pulse oximetry
measurement with the sensor positioned on the tongue (primary), toe (alternate), or at the base of the tail
(alternate).

Sensor Placement:
Model 2000SL Small Lingual Clip Application
The recommended application site for the Nonin Small Lingual Clip is on the tongue of a small animal (dog,
cat, etc.)
Position the tongue clip so it is fully onto the tongue. If the clip is only partially on the tongue, sensor light
may bypass the edge of the tongue, resulting in SpO
CAUTION: If the sensor does not track the pulse reliably, it may be positioned incorrectly or perfusion may be too
low. The oximeter must be able to track the pulse to give accurate readings. Try one of the other sensors
positioned on a different site.
measurement error.

Figure 2. Small Lingual Clip Placement
Model 2000SA Small Animal Flex Sensor Application
The Small Animal Flex Sensor is suitable for use on the toe of a dog or the base of the tail on very small
animals such as rats.
Shave the site completely before sensor application. Position the light emitter and light detector of the sensor
such that sensor light is directed through the tail or toe.
NOTE: Mis-positioning might allow sensor light to bypass the toe or tail resulting in SpO
measurement error.

Secure the sensor with tape, ensuring that the tape does not restrict perfusion.
Model 2000T Transflectance Sensor Application
The 2000T Transflectance sensor is designed for placement on the underside, base of the tail (near the anal
orifice) of a dog.
Shave the site completely before sensor application. Position the light emitter and light detector of the sensor
against the underside of the tail at the base near the anal orifice. Secure the sensor with tape, ensuring that the
tape does not restrict perfusion.
Batteries
The Model 8500AV Oximeter is powered by 6 AA Alkaline cells that will typically allow 100 hours of continuous
operation. The Model 8500AV Oximeter indicates when the batteries are low by flashing the digital displays at a one
second rate. The batteries should be replaced as soon as possible. Replace the batteries by removing the door on the
bottom of the Model 8500AV Oximeter. Be sure to follow the polarity markings on the case when installing new
batteries. Rechargeable Nickel Cadmium batteries may be used in the Model 8500AV Oximeter. Since NiCad batteries
have less than half of the capacity of alkaline batteries, they will have to be replaced more often.
If the clock functions are being used, they need to be reset after the batteries are replaced.

Features
Controls
All functions of the Model 8500V series are controlled by switches found on the front of the unit.
Power
Pressing the "1" switch causes power to be applied to all the internal circuitry upon actuation. The "1" switch has
additional clock and printer mode setting functions when used with the arrow switch. The "0" switch causes power to
be removed from the displays and puts the oximetry circuitry into a low power standby mode when pressed. The clock
continues to function in the low power standby mode (when enabled). In order to conserve battery life, the 8500AV
will shut itself off after 10 minutes of inactivity. Inactivity is indicated by dashes in the displays and is caused by:
• no sensor connected to the 8500AV oximeter
• the pulse is too low
• the sensor is not attached to a patient
Each time a reading is displayed, the 10 minute timer is restarted.
Audible Heart Beat Tick or Display Intensity
On the 8500AV, the arrow switch causes the Audible Heart Beat Tick to toggle status on or off. The arrow switch has
additional clock and alarm mode setting functions when used with the "1" switch.
Setup Mode
Setup mode is used to control the options of the 8500AV oximeter. These options include time-of-day clock and alarm
settings. The setup mode is initiated by holding the arrow key when the unit is turned on by pressing the "1" key. In
setup mode, the "1" key and the arrow key are used to make the selections. The "1" key is used to advance to the next
setup entry and the arrow key is used to advance the optional value for this entry.
Alarm Settings
"Alr" will appear in the left-hand display, indicating the Alarm mode. "dft" will appear in the right-hand
display. Each time the arrow switch is pressed, the option on the right-hand display will advance. When the correct
value appears in the right-hand display, pressing the "1" switch will advance the left-hand display to the next
parameter listed in Table I. If the "OFF" option is selected, then the alarm functions are disabled and the setup
skips immediately to the printer/clock setup. If the "dft" option is selected, then the standard default values are
loaded into memory, but if the "rcl" option is selected, then the previous user programmed values are reloaded.
These values may be changed with the remaining alarm setting entries. This process is continued until all alarm
parameters are set. When the alarm setting sequence has been completed, the 8500AV continues to the printer and
clock settings (see below).
Printer and Clock Settings
"Prn" will appear in the left-hand display, indicating print setup mode. The "Prn" mode is currently not used.
Advance to the clock setting mode by pressing the "1" switch. Each time the arrow switch is pressed, the number
on the right-hand display will increment. It starts with the current value for the parameter currently stored in
memory. When the correct value appears in the right-hand display, pressing the "1" switch will advance the lefthand display to the next parameter listed in Table I. This process is continued until all parameters are set. The
settings can be checked easily, since the first value displayed for each parameter represents the current setting.
When the setting sequence has been completed, the 8500AV exits the clock setting modes and begins normal
operation.
NOTE: Setting the month to 00 disables the clock function and helps conserve battery life.

Displays
Equipment Indications
Sensor
If the Model 8500AV determines that a sensor fault exists (sensor disconnect, sensor failure, or sensor
dislodgment), a minus (-) sign appears in the left-most digit of the SpO
display. The readings that are being
2
displayed will remain unchanged while the sensor fault exists. Dashes will be displayed 10 seconds after the minus
sign appears if the sensor fault is not corrected.
Battery Low
If the Model 8500AV determines that a battery low condition exists, then the numerical displays will flash on and
off at a one second rate and the batteries must be replaced.
Status Indicator
Perfusion
The perfusion indicator (identified by the waveform symbol) will flash green for each adequate strength pulse for
measuring oxygen saturation. If the pulse becomes non discernible, the indicator will blink red until this condition
terminates. If the pulse strength is marginal or the oximeter recognizes artifact, the light will blink yellow with each
pulse while this condition exists.
The perfusion LED is a simple method of alerting the user to changes in the pulse waveform signal that may affect
the SpO
data. The following is a simple illustration of how to interpret the perfusion LED:
2
• Perfusion LED blinks "GREEN"—pulse waveform signal is of good quality and SpO
data is accurate.
2
• Perfusion LED blinks "Yellow"—pulse waveform signal is of marginal quality and although SpO
acceptable, corrective measures should be considered to improve sensor placement or change sensor type.
• Perfusion LED blinks "RED”—pulse waveform signal is too small or the quality is very poor. SpO
displays will go to dashes after approximately 10 seconds to avoid confusing the user with inaccurate SpO
data.
This simple method gives the user a pulse by pulse visual indication of waveform signal quality without requiring
the user to perform complex waveform analysis during critical patient care situations.
Digital Displays
SpO2 Display
The left digital display is a 3 digit light emitting diode (LED) digital display that displays oxygen saturation
percentage. Reference Figure 1. Oxygen saturation is calculated and displayed using a four beat exponential
averaging technique.

Service and Maintenance
The solid state circuitry within the Model 8500AV Oximeter requires no periodic maintenance or calibration other than
battery replacement. It may be cleaned with a mild detergent and a soft cloth.
NOTE: Do not use caustic or abrasive cleaning agents.
The reusable sensors may be cleaned with isopropyl alcohol solution.
Nonin does not recommend field repair of the Model 8500AV. The circuit board in the 8500AV is a multilayer board
using traces 0.01" wide. Due to the very small trace size, extreme care must be used when replacing components to
prevent permanent nonrepairable damage to the circuit board. Components are surface mounted and require special hot
air jet soldering and desoldering equipment. Most of the work should be done under a microscope set at 25 times
magnification. Use of regular soldering equipment will damage the board and void any applicable warranty.
Nonin will repair out of warranty oximeters for a nominal hourly rate plus parts costs. All repairs include a complete
retest of the oximeter using factory test fixtures.
However, if you choose to repair the oximeter, observe the following cautions:
CAUTION: Any attempt to service by unauthorized individuals will void the warranty.
CAUTION: To prevent damage to the electronic circuitry, work at an anti-static workstation, use ground straps and a
grounded hot air jet soldering system.
CAUTION: After any soldering, thoroughly clean the circuit board with circuit board cleaner (Freon TMS).
CAUTION: Circuitry in the input section must be thoroughly cleaned and protected with Humiseal conformal coating.
After any repairs are made, the oximeter must be tested to ensure correct operation.
