Chapter 8: Oximetry
Veterinary Vital Signs Monitor Operation Manual 8-5
•
The monitor will automatically detect when the SpO2 patient cable is
connected and the oximetry parameter will be active.
5. Attach the sensor to the patient.
a) Make sure the red light in the sensor is illuminated.
b) Select the appropriate sensor size.
8.5 Performance Considerations
WARNING! Pulse oximetery readings and pulse signal can be affected by
certain ambient environmental conditions, sensor application
errors, and certain patient conditions.
NOTE! A Patient Simulator does not calibrate the oximeter. The oximeter
does not require calibration. A Patient Simulator provides a known
SpO
2
value and pulse rate to the oximeter that allows the oximeter's
performance to be checked.
Inaccurate measurements can be caused by:
• Incorrect application of the sensor
• Placement of the sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line
• Ambient light
• Prolonged patient movement
Loss-of-pulse signal can occur for the following reasons:
• The sensor is too tight
• A blood pressure cuff is inflated on the same extremity as the one with the
sensor attached
• There is arterial occlusion proximal to the sensor
Select an appropriate sensor, apply it as directed, and observe all warnings
and Cautions presented in the directions for use accompanying the sensor.
Clean and remove any substance such as nail polish from the application site.
Periodically check to ensure that the sensor remains properly positioned on
the patient.
WARNING! Tissue damage can be caused by incorrect application or
duration of use of a SpO
2
sensor. Inspect the sensor site as
