Introduction
The
Trio
portable patient monitor uses a parameter module as the basis for acquiring patient
data. The results are transmitted to the main control board to process and display the data
and waveforms. CPU board commands and status messages of modules are transmitted via
databus. The structure of the entire system is shown in the figure below.
