Title (EN) CONTINUOUS MONITORING OF THE PERFUSION OF AN ORGAN OR EXTREMITY
(FR) SURVEILLANCE CONTINUE DE LA PERFUSION D'UN ORGANE OU D'UNE EXTRÉMITÉ
Abstract:
(EN) A method and system are provided for continuous monitoring perfusion of an organ or extremity, and for early detection of progressive partial occlusion of arterial blood supply or venous drainage of tissue. The method and system measure a delay in wave propagation of a blood perfusion wave, which is associated with flow of blood through a blood vessel. The delay is correlated to an amount of obstruction in the blood vessel.
(FR) La présente invention concerne un procédé et un système de surveillance continue de perfusion d'un organe ou d'une extrémité, et de détection précoce d'occlusion partielle progressive de l'irrigation artérielle ou du drainage veineux de tissu. Le procédé et le système mesurent un retard dans la propagation d'onde d'une onde de perfusion sanguine, qui est associée à un flux de sang à travers un vaisseau sanguin. Le retard est corrélé à un degré d'obstruction dans le vaisseau sanguin.
