CA 2487393

A method and system for extracting cardiac parameters from a plethysmographic signal is described wherein the plethysmographic signal is passed through a first filter to remove non-cardiac components of the signal. A second filter averages a plurality of cardiac cycles and cardiac parameters are extracted from the averaged cardiac signal.

L'invention concerne un procédé et un système d'extraction de paramètres cardiaques de signaux de pléthysmographie, signal envoyé dans un premier filtre pour que les composantes non cardiaques du signal soient éliminées. Un second filtre moyenne plusieurs cycles cardiaques et des paramètres cardiaques sont extraits du signal cardiaque moyenné.
