Health monitor is based on emission spectroscopy in the visible wavelength range of glow discharge. The device has a high spectral selectivity.
Application of the signal normalization using discharge parameters can dramatically increase the accuracy of measurement in the patient's breathing
Also, this principle excludes the presence of water vapor and other gases, isolating the necessary spectru
Thus, before each test, a "calibration" occurs. Environmental factors are taken into account, after which the patient is offered to conduct testing.
