Abstract

La présente invention concerne un système d'assistance respiratoire configuré pour travailler avec un mécanisme pour réaliser un exercice physique. Le système d'assistance comprend un capteur d'activité qui génère des données de mesure d'activité, et un capteur respiratoire qui génère des données de mesure respiratoire. Une unité de commande est utilisée pour stocker les données générées et mettre en corrélation les données de mesure d'activité avec les données de performances pulmonaires. Le système comprend facultativement un régulateur de gaz configuré pour pouvoir être relié à une source de gaz et pour commander la distribution de gaz à un patient.
