Pulsed Eco Doppler for Polmonal Discharge Velocity

Sponsor: IRCCS Azienda Ospedaliero-Universitaria di Bologna

Summary

Chest ultrasound is increasingly being used in the diagnosis and management of the respiratory patient. With ultrasound, ultrasound artifacts representing the lung during inspiration and during exhalation are visualized and analyzed. During inspiration, the lung inflates with air while when exhaling, the lung empties. These two phases are visualized on ultrasound with a sliding motion of the pleural line, which represents the margin of the lung. The aim of the study is to identify the speed of filling and emptying of the lung by studying the characteristics of the pulsed Doppler wave to measure the speed of lung sliding as the significance of this finding has not yet been clarified. In both healthy subjects and patients with lung disease, it is not known whether there is a correlation between velocity measured by the Doppler wave with the main data recorded by a mechanical ventilator or spirometer.
