Title
(EN) QUANTITATIVE NEUROMUSCULATURE BLOCKADE SENSING SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION QUANTITATIVE D'UN BLOCAGE NEUROMUSCULATURE
Abstract
(EN) Neuromuscular monitoring is described that uses a novel lead assembly and a monitor that can select the appropriate electrodes on the lead assembly and calibrate the stimulation signals applied to the patient through the lead assembly. The monitoring can also set a noise floor value to reduce the likelihood of an erroneous train of four calculations. The present system can automatically sense train of four response of a patient and reduce the likelihood of false train of four indications.
(FR) La présente invention concerne une surveillance neuromusculaire qui utilise un nouvel ensemble câblage et un moniteur qui peut sélectionner les électrodes appropriées sur l'ensemble câblage et étalonner les signaux de stimulation appliqués au patient par l'intermédiaire de l'ensemble câblage. La surveillance peut également régler une valeur plancher de bruit pour réduire la probabilité d'un train erroné de quatre calculs. Le présent système peut détecter automatiquement un train de quatre réponses d'un patient et réduire la probabilité d'un faux train de quatre indications.
