The present invention refers to a system and a method for the automatic detection of the expiratory flow limitation of a subject. In an embodiment thereof the system for the automatic detection of expiratory flow limitation of a subject comprises: means for determining the respiratory impedance of said subject composed of an imaginary component and, eventually, of a real part or, at least, means to apply a forcing signal with one or more spectral components to the airway opening of a subject combined with means to measure time courses of pressure and flow at the airway opening; means for determining at least one index linked to said respiratory impedance or pressure and flow time courses; means for indicating the positioning of said at least one index in relation to a preset threshold value.

Abstract
The present invention refers to a system and a method for the automatic detection of the expiratory flow limitation of a subject. In an embodiment thereof the system for the automatic detection of expiratory flow limitation of a subject comprises: means for determining the respiratory impedance of said subject composed of an imaginary component and, eventually, of a real part or, at least, means to apply a forcing signal with one or more spectral components to the airway opening of a subject combined with means to measure time courses of pressure and flow at the airway opening; means for determining at least one index linked to said respiratory impedance or pressure and flow time courses; means for indicating the positioning of said at least one index in relation to a preset threshold value.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
