This sensor can be placed on the right side, left side, or the end of the tongue. Wait approximately 10 to 15 seconds for an adequate pulse signal. If you are unable to obtain an SpO2 reading, move the sensor to another site on the tongue and wait 10 to 15 seconds until an adequate pulse signal is displayed. It is a good idea to secure the cables so the weight of the cable doesn’t move the sensor. If you still have difficulty getting an SpO2 reading, examine the tongue to see if it is quivering. This could be a reaction to certain medications. If the tongue continues to quiver, choose a different sensor site.

• The vulva or prepuce
  • If the animal is large enough, it has been reported by some veterinarians that the prepuce or vulva might be an alternate site for the lingual clip sensor. Remember that this site must be well perfused and not pigmented.
• Achilles tendon: On light colored animals (a color of gray or lighter), an alternate application site may be the Achilles tendon. Remove the hair and make sure the skin is not pigmented.
