10. SpO2
Overview
SpO2 monitoring is a non-invasive technique that measures the total amount of oxygen in
hemoglobin. The pulse rate is measured by measuring the absorption of the wavelength of the
selected light. The light emitted by the sensor in the probe passes through the tissue and is
converted into an electrical signal by the light-detecting sensor in the probe. The monitor processes
the electrical signal and displays the waveform, %SpO2, and pulse rate on the screen as quantified
values. Red and infrared light are passed through the capillaries of the animal's tongue to detect
pulsating waveforms, calculate pulse rate and blood oxygen saturation, and perform alarm functions
according to the set alarm value.
Precaution
SpO2 measurements are particularly sensitive to arterial and arteriolar pulse rates. Animals
experiencing shock, hypothermia, anemia, or animals taking medications that reduce arterial blood
flow may have incorrect measurements.
Warning
The pulse oximeter cannot be used as an apnea monitor.
Visually check the attachment state of the sensor frequently and make sure it
is properly attached.
Use only Bionet-designated sensors. Other sensors may not provide
adequate protection against defibrillation or may put the animal at risk.
Disposable accessories (disposable electrodes, transducers, etc.) should be
used only once. Do not reuse disposable accessories.
Animal preparation
The accuracy of SpO2 monitoring is largely dependent on the strength and quality of the SpO2
