Abstract

L'invention concerne un calorimètre indirect permettant de mesurer la vitesse de métabolisme d'un sujet. Ce calorimètre comprend un calorimètre respiratoire (10) prévu pour être supporté en contact avec le sujet de manière à laisser passer les gaz inspirés et expirés lorsque ce sujet respire. Un voie d'écoulement (22) peut fonctionner pour recevoir et laisser passer les gaz inspirés et expirés. Une première extrémité de la voie est en communication par le fluide avec le connecteur respiratoire (20) et une deuxième extrémité est en communication par le fluide avec une source et un puits pour les gaz respiratoires. Un débitmètre génère des signaux électriques en fonction du volume d'écoulement instantané de gaz inspirés et expirés passant dans cette voie. Un capteur de concentration (84) des gaz composants génère des signaux électriques en fonction de la fraction instantanée d'un gaz composant prédéterminé dans les gaz expirés lors du passage des gaz dans la voie. Une unité de calcul (96) reçoit les signaux électriques fournis par le débitmètre et le capteur de concentration (84) des gaz composants et calcule au moins un paramètre respiratoire pour le sujet lors de la respiration de ce dernier dans le calorimètre (10).
