To provide a method for measuring a consciousness level of an object body, using a learned artificial neural network, and a computer program.SOLUTION: A method for measuring a consciousness level of a patient comprises: a step of extracting a component of one or more frequency bands from a first section of a brain wave; a step of calculating a first index for each component of the one or more frequency bands, that is a step of calculating the first index on the basis of a degree at which, magnitude of each component of the one or more frequency bands with respect to magnitude of a prescribed standard component in the first section, exceeds a prescribed critical value; a step of calculating a probability value for one or more states of each patient, on the basis of the first index with respect to each component of the one or more frequency bands, using a learned artificial neural network; and a step of determining a consciousness level of the patient, on the basis of the probability value with respect to the calculated one or more states of each patient.SELECTED DRAWING: Figure 11
