5.2 SpO2 Monitoring
5.2.1 Introduction
SpO2 monitoring is a non-invasive technique used to measure the amount
of oxygenated haemoglobin and pulse rate by measuring the absorption of
selected wavelengths of light. The light generated in the probe passes
through the tissue and is converted into electrical signals by the
photodetector in the probe. The MCU processes the electrical signal and
displays on the TFT LCD digital values for SpO2 and pulse rate.
The sensor measurement wavelengths are 666nm for the red LED and
905nm for infrared LED.
5.2.2 Monitoring Procedure
Sensor selection for SpO2 measurement depends on the animal type. For
an adult animal, choose a finger SpO2 sensor; for an infant animal,
choose a hand or toe sensor. Refer to the following procedure.
1. Power on the monitor.
2. Attach the sensor to the proper site on the animal, as Figure 5-2.
3. Plug the connector of the sensor extension cable into the SpO2
connector on monitor.
