Identification of Respiratory Profiles From Nasal Pressure Signals (IPR-SAINS)

Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease caused by smoking and associated with significant morbidity due to recurrent exacerbations or even hospitalizations. It is one of the leading causes of death in rich countries.

Early detection of exacerbations of the disease is thus an economic and public health issue in the world. Finding tools for automatic and early detection of an exacerbation is the subject of the study. A continuous analysis of the frequency and shape of the patients' breathing will be used.

As a first step in this study, investigators want to measure the frequency and shape of breathing in healthy subjects as they execute standard activities. These activities include resting, drinking, coughing, speaking, breathing through the mouth, physical exercise and recuperation.
