Non-invasive monitoring system for cardiac output

The invention discloses a non-invasive monitoring system for cardiac output. The non-invasive monitoring system comprises a data acquisition control module, a non-invasive peripheral arterial blood pressure measurement module, a waveform screening module, a data preprocessing module, a cardiac output calculation module and a data display module; the data acquisition control module is used for controlling a data acquisition and data transmission process; the waveform screening module is used for classifying and screening peripheral arterial blood pressure waveforms to obtain A-type waveforms; the data preprocessing module is used for preprocessing A-type waveforms and sending the A-type waveforms to the cardiac output calculation module; the cardiac output calculation module comprises a neural network trained through a sample set, the trained neural network has the end-to-end recognition capability, namely, peripheral arterial blood pressure waveforms are input, corresponding cardiac output is output, and the
