Title
(EN) SYSTEM AND METHOD FOR QUANTIFYING LUNG COMPLIANCE IN A SELF-VENTILATING SUBJECT
(FR) SYSTÈME ET PROCÉDÉ DE QUANTIFICATION DE LA COMPLIANCE PULMONAIRE CHEZ UN SUJET EN VENTILATION AUTOMATIQUE
Abstract
(EN)
The lung compliance of a subject that is at least partially self-ventilating is determined. The quantification of lung compliance may be an estimation, a measurement, and/or an approximate measurement. The quantification of lung compliance may be enhanced over conventional techniques and/or systems for quantifying lung compliance of self-ventilating subjects in the lung compliance may be quantified relatively accurately without an effort belt or other external sensing device that directly measures diaphragmatic muscle pressure, and without requiring the subject to manually control diaphragmatic muscle pressure. Quantification of lung compliance may be a useful tool in evaluating the health of the subject, including detection of fluid retention associated with developing acute congestive heart failure.
(FR)
L'invention porte sur la détermination de la compliance pulmonaire d'un sujet qui est au moins partiellement en ventilation automatique. La quantification de la compliance pulmonaire peut être une estimation, une mesure et/ou une mesure approximative. La quantification de la compliance pulmonaire peut être améliorée, par rapport aux techniques et/ou systèmes classiques de quantification de la compliance pulmonaire des sujets en ventilation automatique, et peut être quantifiée avec une relative précision sans ceinture d'effort ni autre dispositif de détection externe qui mesure directement la pression du muscle du diaphragme, et sans avoir besoin que le sujet commande manuellement la pression du muscle du diaphragme. La quantification de la compliance pulmonaire peut être un outil utile dans l'évaluation de la santé du sujet, notamment pour la détection de la rétention hydrique associée au développement de l'insuffisance cardiaque congestive aiguë.
