Abstract

The occurrence of a hypopnoea can be detected with high reliability based on a recorded number of sample values describing a respiratory sound if an energetic value is calculated from the sample values, said value describing the energy contained in the respiratory sound within a given period. The occurrence of an hypopnoea can be detected by carrying out the energetic value with a variable reference value which depends on the respective patient, thereby eliminating negative external influences such as e.g. different sensitivities of the microphone or different noise intensities of the respiratory sound of different patients.
