CA 2473582

An apparatus and method for detection and monitoring of autonomic nervous system (ANS) activity in humans, primarily in the field of sleep research. The present invention discloses a portable, simple and cost-effective electronic device containing hardware and software that permits real-time monitoring of a pulsatile blood volume obtained through the use of a photoplethysmographic (optical volume detecting) probe (83), thereby allowing signal conditioning, waveform slope analysis, display, recording, and output of pulse transitional slope data representative of activity in the ANS.

L'invention concerne un appareil et un procédé permettant de détecter et de surveiller l'activité du système nerveux autonome (ANS) chez l'être humain, principalement dans le domaine de la recherche sur le sommeil. L'invention concerne un dispositif électronique portable, simple, et économique contenant du matériel informatique et un logiciel permettant de surveiller en temps réel la forme d'onde pulsatile du volume sanguin obtenue au moyen d'une sonde de photopléthysmographe (détection optique du volume), ce qui permet de procéder au conditionnement de signaux, à l'analyse de l'inclinaison de la forme d'onde, à l'affichage, à l'enregistrement et à la sortie de données d'inclinaison de transition d'impulsion représentant l'activité dans l'ANS.
