Monitoring SpO

8.1 Introduction
SpO
2
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 SpO
2
module processes the electrical signal
and displays a waveform and digital values for SpO
2
and pulse rate. It provides four
measurements:
1. Pleth waveform (Pleth): visual indication of patient’s pulse.
2. Oxygen saturation of arterial blood (SpO
2
): percentage of oxygenated hemoglobin in
relation to the sum of oxyhemoglobin and deoxyhemoglobin.
3. Pulse rate (derived from pleth wave): detected pulsations per minute.
4. Perfusion indicator: the pulsatile portion of the measured signal caused by arterial
pulsation.
