3.2.6 SPO2 Module
There are 3 types of SPO2 modules: Analog SPO2, Masimo SPO2 and Nellcor SPO2 module.
The SPO2
board implements SPO2
signals collection, amplified simulation, relative digital/analog
conversion and signal processing.
The pulse extent of optical signal changes during monitoring. SPO2 parameter, pulse rate signal and pleth
waveform will be acquired after calculation. These data will be transmitted to the main board with special
communication protocol.
