  • METHOD OF GENERATION OF A STATE INDICATOR OF A PERSON IN COMA
    Publication number: 20210022638
    Abstract: This method for generating an indicator of the state of a patient in coma includes: generating at least one auditory stimulation by generating a sequence of auditory stimuli, the sequence producing evoked potentials in the patient; acquiring a first electroencephalographic signal produced by patient from at least one electrode; estimating at least one pair of values corresponding to a first parameter and a second parameter extracted from the first acquired signal, including estimating a first pair of values such that calculating the first parameter includes an estimation of the amplitude variance of the first signal within a predefined time window and the calculation of the second parameter includes an estimation of the correlation of two segments of the first signal; generating a state indicator for the or each pair of values of the first and second parameters, the values defining coordinates of a point in a reference base.
