The baseline evaluation will include sociodemographic, anthropometric and clinical data, the calculation of Wang's score and well as computerized lung auscultation. The lung sounds are recorded on 7 anatomic regions: trachea (sternum node) left and right anterior regions (middle clavicular line over the 2nd intercostal space), left and right lateral regions (axillary line over the 4th / 5th intercostal space), left and right back regions (5 cm from the para-vertebral line and 7 cm under the inferior angle of scapular) for approximately 20 seconds.
