Recording breathing volumes with magnetic motion sensors, dedicated to COPD during the CPT session

摘要

COPD is the third leading cause of death worldwide. Such pathologies require airway clearance methods implemented during CPT sessions. Monitoring breathing volumes during a session could provides the understanding of the techniques, as well as the time tracking of obstructions. Spirometry and thoracic movement measurements are performed on healthy subjects thanks to a dedicated innovative device, to calculate FEV1/FVC% index. We compare the obtained results with the motion sensors with those of the spirometer using the Bland-Altman plot method. This measuring system allows monitoring the evolution of the respiratory volumes during a CPT session.
