6.1 Outline
SPO2 monitoring is a noninvasive technique used to measure the amount of oxygenated
hemoglobin 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 an electrical signal by the
photodetector in the probe. The monitor processes the electrical signal and displays on the screen a
waveform and digital values for SpO2 and pulse rate. It detects SpO2 in the way of transmitting the
red and infrared rays into the capillary vessel to take the pulsation. Also perform the alarm function
according to the setting value.
