Indications for Use
Warnings (Continued)
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.
Verify all alarm settings and limits during system startup to ensure that they are set as intended.
Before changing the batteries, make sure the device is off and the sensor is not applied to the animal.
Cautions
Before use, carefully read the package insert provided with the sensors.
This device is not an apnea monitor.
Verify that all visible indicators illuminate and that an audible indicator sounds during the startup (initialization)
sequence. If any indicator is not lit or the audible indicator does not sound, do not use the device. Contact Nonin
Technical Service for assistance.
Review all limits to ensure they are appropriate for the animal.
Setting alarm limits to extremes can render the alarm system useless.
The presence of a defibrillator may interfere with the performance of this device.
This device may not work on all animals. If you are unable to achieve stable readings, discontinue use.
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 “Monitoring.” If proper
operation cannot be verified, remove the sensor from the animal and DO NOT use the oximeter on the animal.
This device has motion tolerant software that minimizes the likelihood of motion artifact being misinterpreted as good
pulse quality. In some circumstances, however, the device may still interpret motion as good pulse quality. Minimize
animal motion as much as possible.
Do not place the Model 2500A VET in liquid or clean it with agents containing ammonium chloride, isopropyl alcohol, or
products that are not listed in this operator’s manual.
Do not autoclave or immerse the device or sensors in liquid. Do not expose the device or components to excessive
moisture or liquids.
Do not use caustic or abrasive cleaning agents on the device or the sensors.
The oximeter sensor might not work on cold extremities due to reduced circulation. Warm or rub the sensor site to
increase circulation, or reposition the sensor.
Sensor sites must be checked periodically to determine circulation, sensor positioning, and tissue sensitivity.
Replace the batteries as soon as possible after a low battery indication. Always replace the batteries with fully charged
batteries.
Use only Nonin-specified battery types with this device.
Do not use fully charged and partially charged batteries at the same time. This may cause the batteries to leak.
Do not remove any covers other than the battery cover when replacing batteries. There are no user-serviceable parts
inside other than the replaceable batteries.
Follow local, state, and national governing ordinances and recycling instructions regarding disposal or recycling of the
device and device components, including batteries.
Batteries may leak or explode if used or disposed of improperly.

Replace batteries within 30 seconds to avoid losing settings (date, time, and data stored in memory) or corrupting data.
Use only the Nonin-branded Model 2000SL, 2000T, or 2000SA veterinary sensors for monitoring. These sensors are
manufactured to meet the calibration requirements for the Nonin Model 2500A VET 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.
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 veterinary professional 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 pulse oximeter sensor, make sure to secure the sensor in a manner that will not restrict perfusion.
An improperly applied sensor could inhibit proper function of the pulse oximeter and cause discomfort or localized
ischemia to the animal.
Failure of a network data coupling (serial cable/connectors) will result in loss of data transfer.

Veterinary Sensors
The Model 2500A VET pulse oximeter features sensors ideal for a variety of veterinary applications.
Each sensor is designed for a specific site application and specific animal size. The sensors include:
• Small Lingual Clip (2000SL) – Recommended for spot checks or short-term continuous
monitoring. For most small animals, the sensor performs best when used on the tongue.
• Small Animal Flex Sensor (2000SA) – Suitable for use on the toe of a dog and on the paw or at
the base of the tail on very small animals (e.g., rats).
• Transflectance Sensor (2000T) – Suitable for placement on the underside, base of the tail (near
the anal orifice) of a dog.
Nonin’s veterinary sensors are reusable. Clean them with a mild detergent. Allow enough time for
the sensor to dry thoroughly before reusing.
CAUTION: Use only the Nonin-branded Model 2000SL, 2000T, or 2000SA veterinary
sensors for monitoring. These sensors are manufactured to meet the calibration
requirements for the Nonin Model 2500A VET 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.
• moisture in the sensor (for non-lingual
applications)
• improperly applied sensor
• incorrect sensor type
• inadequate signal

Alarms
This section describes the alarm functions of the Model 2500A VET. The device features audible
and visual alarms that indicate both high and medium priority alarm conditions.
WARNING: 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.
High Priority Alarms
High priority alarms (table 4) are animal-specific and are indicated by a flashing red Alarm Bar and
a high priority audible alarm.
High priority alarms sound as 3 beeps, a pause, 2 beeps, and a 10-second pause. This cycle repeats
until silenced.

Memory Functions
Memory Functions
Data Collection
Each time the Model 2500A VET is turned on (except during Setup mode), data are automatically
collected in memory. The device can collect and store up to 72 hours of SpO
information.
NOTE: Only recording sessions longer than 1 minute are stored in memory. Memory will clear
approximately 30 seconds after removing the batteries. Replace batteries immediately to avoid
losing stored data.
The memory in the device functions as an “endless loop.” When the memory fills up, the unit begins
overwriting the oldest data with the newest.
Each time the device is turned on, the current time/date information (if the clock is set correctly) is
stored in memory to allow quick differentiation of recording sessions. SpO

Oxygen saturation values are stored in 1% increments in the range of 0 to 100%.
The 2500A VET memory stores pulse rates from 18 to 450 beats per minute. The stored values are
in increments of 1 pulse per minute.
During the printing of the data, the last data recorded are the first data printed. For example, the last
4 minutes of data recorded would be the first 4 minutes of printout.
Memory Playback
NOTE: Playing back the data in memory does not clear the data from memory.
1. Connect the 2500A VET to a computer with the Memory Cable (1000MC), Real-Time Cable
(1000RTC), or USB Interface Adapter (1000USB/1000USB-C).
2. Enter Setup mode (see “Entering Setup Mode”).

4. After 8 seconds, data automatically plays back from the memory at a rate of 20 minutes of
data per second. A 72-hour recording session (the maximum memory saved) is played back in
approximately 3.5 minutes.

Animal information is held in memory as long as the batteries are sufficiently charged. If the memory
must be cleared, see “Clearing the Memory.”

Serial Output
The Model 2500A VET provides real-time data output capability via the pulse oximeter sensor
connector (a 9-pin Sub-D connector). The pulse oximeter sensor connector pin assignments are
listed in table 6.
Information from the device, in the real-time mode, is sent in an ASCII serial format at 9600 baud
with 9 data bits, 1 start bit, and 1 stop bit. The data are output at a rate of once per second.
NOTE: The 9th data bit is used for odd parity in memory playback mode. In real-time mode, it is
always set to the mark condition. Therefore the real-time data may be read as 8 data bits, no
parity.
Real-time data may be printed or displayed by devices other than the pulse oximeter. On power up,
a header is sent identifying the format and the time and date. Thereafter, the data are sent once per
second in the following format:
SPO2=XXX HR=YYY
Where “XXX” represents the SpO
value and “YYY” represents the pulse rate. The SpO2 and pulse

Connecting the Device into a Medical System
Incorporating the device into a medical system requires the integrator to identify, analyze, and
evaluate the risks to patient, operators, and third parties. Subsequent changes to the medical
system after device integration could introduce new risks and will require additional analysis.
Changes to the medical system that must be evaluated include:
• Changing the system configuration
• Adding devices to or disconnecting devices from the system
• Updating or upgrading equipment connected to the system
Issues resulting from user-initiated system changes may include corruption or loss of data.
NOTES:
• When using the serial port to connect the device to other equipment, follow each device’s
cleaning instructions.
• Verify all equipment connected to the device is suitable for the patient’s environment.
CAUTION: Failure of a network data coupling (serial cable/connectors) will result in
loss of data transfer.

NOTES:
• At 80 MHz and 800 MHz, the higher frequency range applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the device is used exceeds the applicable RF
compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Testing Summary
SpO2 accuracy, and low perfusion testing were conducted by Nonin Medical, Inc., as described
below:
SpO2 Accuracy Testing
During motion and no-motion conditions at an independent research laboratory, SpO2 accuracy
testing is conducted during induced hypoxia studies on healthy, male and female, non-smoking,
light- to dark-skinned human subjects that are 18 years of age and older. The measured arterial
hemoglobin saturation value (SpO
(SaO
) value, determined from blood samples with a laboratory co-oximeter. The accuracy of the
2
sensors in comparison to the co-oximeter samples measured over the SpO
Accuracy data is calculated using the root-mean-squared (A
ISO 80601-2-61 Medical Electrical Equipment—Particular requirements for the basic safety and
essential performance of pulse oximeter equipment for medical use.
Pulse Rate Motion Testing
This test measures pulse rate oximeter accuracy with motion artifact simulation introduced by a
pulse oximeter tester. This test determines whether the oximeter meets the criteria of ISO 80601-261 for pulse rate during simulated movement, tremor, and spike motions.

Technical Information
Principles of Operation
Pulse oximetry is a non-invasive method that passes red and infrared light through perfused tissue
and detects the fluctuating signals caused by arterial pulses. Well-oxygenated blood is bright red,
while poorly oxygenated blood is dark red. The pulse oximeter determines functional oxygen
saturation of arterial hemoglobin (SpO
) from this color difference by measuring the ratio of
2
absorbed red and infrared light as volume fluctuates with each pulse.
