Cautions (Continued)
Portable and mobile RF communications equipment can affect medical electrical equipment.
Place a dark cloth or surgical drape over the pulse oximeter sensor in order to reduce interference from ambient light.
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 SpO
- excessive ambient light
- excessive motion
- electrosurgical interference
- blood flow restrictors (arterial catheters, blood
pressure cuffs, infusion lines, etc.)
- improperly applied sensor
- incorrect sensor type
- inadequate signal
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.
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor.
Ensure all connections to the airway adapter tube are tight and leak-free, and that the airway adapter tube is properly
attached to the CO
sensor.

Observe six breaths before interpreting results.
Do not block the audible indicator speaker holes. Blocking the speakers will significantly reduce the sound volume.
Verify the audible alarms can be heard over the ambient noise of the operating environment.
Failure of a network data coupling (serial cable/connectors) will result in loss of data transfer.

- 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
O have a smaller effect.
