Using the 2500A VET Pulse Oximeter
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 small lingual clip is on the tongue of a small animal (dog,
cat, etc.) (figure 5).
Position the tongue clip so it is fully onto the tongue. If the clip is only partially on the tongue, the
sensor light may bypass the edge of the tongue, resulting in SpO
2
measurement error.

CAUTION:
This device is designed to determine the percentage of arterial oxygen
saturation of functional hemoglobin. Factors that may degrade pulse oximeter
performance or affect the accuracy of the measurement include the following:
CAUTION:
Sensor sites must be checked periodically to determine circulation,
sensor positioning, and tissue sensitivity.
CAUTION:
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.
!
• excessive ambient light
• excessive motion
• electrosurgical interference
• blood flow restrictors (arterial catheters,
blood pressure cuffs, infusion lines, etc.)
• moisture in the sensor (for non-lingual
applications)
• improperly applied sensor
• incorrect sensor type
• inadequate signal
• venous pulsations
• anemia or low hemoglobin concentrations
• cardiogreen and other intravascular dyes
• carboxyhemoglobin
• methemoglobin
• dysfunctional hemoglobin
• residue (e.g., dried blood, dirt, grease, oil)
in the light path
