Cautions (Continued)
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 qualified 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.
The oximeter sensor might not work on cold extremities due to reduced circulation. Warm the sensor site to
increase circulation, or reposition the sensor.
Inspect the pulse oximeter sensor application site periodically to ensure correct sensor alignment and skin
integrity.
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:
- excessive ambient light
- excessive motion
- electrosurgical interference
- blood flow restrictors (arterial catheters, blood
pressure cuffs, infusion lines, etc.)
- moisture in the sensor
- improperly applied sensor
- incorrect sensor type
All parts and accessories connected to the serial port of this device must be certified according to at least IEC
Standard EN 60950 or UL 1950 for data-processing equipment.
The monitor is equipped with automatic barometric pressure compensation. End tidal pCO

Water or other liquid in the sampling tube may cause erroneous CO
Ensure that all connections are tight, leak-free, and properly attached.
Radios and cell phones or similar devices may affect the LifeSense Vet and should be kept at least 2.5 meters
(8 feet) away from the device. 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 towers and TV
broadcast towers may affect accuracy.
