Indications for Use
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.
