METHOD FOR CLASSIFYING A POLYSOMNOGRAPHY RECORDING INTO DEFINED SLEEP STAGES

摘要

The invention relates to a method for classifying a polysomnography recording into defined sleep stages, the method comprising essentially the following steps: - dividing the sleep of a person into a pattern with various sleep stages, - acquiring a multiplicity of items of information relating to bodily functions over a predefined period in the form of data, wherein the acquisition of the multiplicity of items of information comprises at least measuring and storing the electrical activity of the brain over a predefined period while a test person is sleeping, - subdividing the acquired data into time-dependent data blocks, - selecting a predefined number of data blocks from the data blocks, wherein these data blocks contain information relating to the electrical activity of the brain, - automatically evaluating the data relating to the electrical activity of the brain in each selected data block by means of a cross-frequency coupling method, - automatically assigning the evaluated data blocks to a sleep stage.
