Abstract

The invention relates to a method and device for carrying out a signal-processing viewing of a measurement signal that is correlated with the respiratory activity of an individual, for example, of a measurement signal that is correlated with the respiratory gas. The aim of the invention is to provide solutions with which an improved electronic analysis of the signals that are representative with regard to respiratory activity can be achieved. To this end, the invention provides that viewing results are obtained within the scope of a signal-processing viewing of said measurement signal and make a differentiation between obstructive and central respiratory disorders possible. The viewing results are determined, in particular, while taking into account changes of selected breathing characteristics such as, for example, the change in the ratio of inhalation time to exhalation time.
