Abstract

A device and a method for evaluating a signal that can indicate the respiration of a person, particularly suitable for examining a patient with respect to the occurrence of sleep-related breathing disturbances. In one example, a device for evaluating a signal indicative of the temporal course of the respiration of a patient, in particular a respiratory flow signal, includes an electronic evaluation program or circuitry which is configured in such a manner that it evaluates the signal by continuously generating intermediate evaluation results for short signal periods and for longer signal periods being parallel thereto, and performs an identification of respiratory patterns in the time signal or in specific time periods on the basis of the position of the intermediate evaluation results of the short signal periods relative to the intermediate evaluation results of the longer signal periods.
