Study of Physiological Signals During and After COPD Exacerbations

Background : Acute exacerbations of COPD (Chronic Obstructive Pulmonary Disease) are frequent events in the course of the disease and they can deteriorate the respiratory function of the patients, impact their quality of life and even potentially threaten their life. It is therefore crucial to prevent these exacerbations from occurring. Aim of the study : Investigate how cardiorespiratory parameters of COPD patients differ between exacerbation phases and their nominal state in order to identify predictors of COPD exacerbations. Study design : Patients admitted at one of the investigation centers on a suspicion of COPD exacerbation will be enrolled on a voluntary basis. Enrolled patients' cardiorespiratory parameters will be monitored with a connected wrist-worn pulse oximeter (BORA Band) during the hospitalisation phase and one month after they have been discharged. Setting : 4 investigative centers across Brittany Patients : 50 patients will be enrolled in the study
