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 HR 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
signal. Install a sensor at the tip of the animal's tongue for the SpO2 measurement.
Only use sensors provided by Bionet and apply them according to manufacturer's
recommendations on a per-sensor basis.
If the sensor is not attached correctly, the ambient light may interfere with the pulse oximetry,
making the measurement irregular or causing the value to disappear. If you suspect interference
from ambient light, make sure that the sensor is properly positioned and that the sensor cover
