Using the 2500A VET Pulse Oximeter
7. Three beeps sound.
8. A dash ( - ) appears in the center digit of the SpO
2
and pulse rate displays until a valid pulse
signal is detected.
NOTES:
• The 2-minute alarm silence feature is automatically enabled immediately after the startup
sequence.
• This startup sequence varies slightly when entering Setup mode at power on.
Monitoring
Verify the pulse oximeter sensor is properly positioned on the animal. Ensure the pulse oximeter is
sensing adequate pulse quality by verifying:
1. Pulse Quality indicator blinks green
.
2. Pulse rate and SpO
2
displays show readings.
3. Pulse Quality indicator blinks in time with the pulse rate for at least 10 seconds.
If the Pulse Quality indicator blinks red or amber or blinks erratically, reposition or replace the sensor.
If the sensor is not properly positioned, or a sensor is not attached to the pulse oximeter after startup
(a few seconds after powering on), both the SpO
2
and pulse rate displays will display a single dash
until a valid pulse signal is detected.
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.
