1. A device, comprising:

  • a signal processing module configured to;

    receive photoplethysmography (PPG) signals, wherein the PPG signals include a first spectral response obtained from light reflected around a first wavelength from skin tissue of a patient and a second spectral response obtained from light reflected around a second wavelength from skin tissue of a patient, and wherein the first wavelength has a high absorption coefficient for nitric oxide (NO) and wherein the second wavelength has a lower absorption coefficient for NO;

    generate PPG input data using the PPG signals, wherein the PPG input data includes at least one of;

    the first spectral response and the second spectral response;

    orone or more parameters obtained from the first spectral response and the second spectral response; and

    a neural network processing device configured to;

    generate an input vector including the PPG input data; and

    determine an output vector including health data, wherein the health data includes one or more of;

    an oxygen saturation level, an NO concentration level or a glucose concentration level.
