About

hronic obstructive pulmonary disease (COPD) is a common lung disease that can worsen suddenly, leading to hospital admission. During these exacerbations, breathing becomes unstable and recovery is difficult to predict. Currently, doctors lack simple tools to monitor how patients recover day by day during hospitalization and after discharge.

This observational study aims to describe how breathing patterns during sleep change over time in patients hospitalized for a COPD exacerbation. Breathing will be monitored using standard sleep recordings and a non-contact sensor placed under the mattress, which measures breathing without disturbing the patient.

By better understanding how nocturnal breathing variability evolves during recovery, this study may help identify early signs of improvement or deterioration, support safer hospital discharge decisions, and improve follow-up after hospitalization for COPD exacerbation
