Acoustic and volumetric measurements to assess bronchial congestion in patients with obstructive respiratory pathologies as part of their management in de-congestion Respiratory Physiotherapy.

Objectives

The aim of this project is to objectively determine the state of congestion of patients suffering from respiratory diseases such as chronic obstructive pulmonary disease (COPD, 3rd cause of death according to the WHO). At present, there is no cure for this disease, and treatment consists in prescribing respiratory physiotherapy (RK) sessions to perform, in particular, bronchial cleansing. Various de-cluttering techniques are used, but the level of scientific evidence on their efficacy remains insufficient, and there is no consensus among professionals. A device capable of objectivizing patients' state of congestion before, during and after their session would enable us to better understand these techniques, and thus to address this issue, and even to adapt the management technique to the patient's profile.

We have therefore developed the SYBILLE device to perform measurements on patients undergoing outpatient treatment, as well as on a control group. This vest simultaneously measures respiratory volumes using 8 position sensors (TrakStar © system), and chest sounds using 10 stethoscope horns associated with electret microphones. It has also been optimized to meet the constraints imposed by our clinical study (ease of disinfection, rapid implementation, etc.). The measurements obtained with this vest will be used to define and calculate a score representative of the patient's encumbrance. This score will be compared with that determined by formalizing practitioners' clinical observations.
