Pulse-Ox Transflectance Sensor (A-PO2-ATR)

Transflectance Sensor used in conjunction with the PO2-300 Pulse Oximeter for measuring blood oxygen saturation (SPO2) in small animals.


SKU A-PO2-ATR Category

The smallest probe we offer; ideally suited for continuous monitoring. Can be placed on the underside of the animal, at the base of the tail, or on other well-perfused surfaces. An excellent option during dental procedures.

The transflectance sensor requires more technique to use than the lingual sensor.

Tips for using the transflectance sensor are:

  • If you wrap this sensor too tightly, you may impede perfusion to the sensor site. Wrap this sensor so that it is “snug”. If the sensor is wrapped too loosely, it may move and display erroneous readings.
  • The most common site for this sensor is at the base of the tail close to the anus. Be sure there is no hair at this site and that the skin is not pigmented.
  • Another site to consider is a pink paw pad*. Be sure the pink area of the pad will cover the front and back diodes on the sensor. Don’t wrap it too tightly. Wait 10 to 15 seconds for an adequate pulse signal. If the transflectance sensor is used between the toes*, in the webbed area, make sure to remove any dark hair and position the sensor up against the webbing. Wrap the whole foot with enough pressure to hold the sensor in place, but not enough to impede perfusion.
  • An optional site is the metatarsal*. There is a spot immediately behind the large pad that has a slight indentation. Remove the hair and wrap the ankle securely, without too much pressure, and wait 10 to 15 seconds to see if you get a good pulse signal every time the heart beats.

When monitoring oxygen saturation (SpO2), the sensor site must meet the following criteria:

  • Sensor site must be well perfused.
  • Sensor site must allow light to be transmitted through the tissue. (Skin must not be overly pigmented and fur/feathers etc. may need to be removed.)
  • Sensor site must allow proper attachment of the sensor.
    (Note: Certain veterinary drugs may cause reduced perfusion to the sensor site. This could compromise the function of a pulse oximeter.)
