PULMONARY VENTILATION REGIONALIZATION OPTIMIZATION DEVICE BY TITRATION EXTRATHORACIC POSITIVE PRESSURE

Lung injury is not homogeneous because lesions are frequently distributed in the posterior regions. This exposes the lungs to inhomogeneous ventilation under mechanical ventilation with risk of overdistension of the anterior and
cyclic opening-closing of the posterior regions. These two phenomena can aggravate lung damage and lead to excess mortality. Today, no technical solution allows the homogenization of the pulmonary aeration except the prone position. The research team develops «STRAPVENT», a device whose objective is to apply a titrated compression on the compliant anterior chest wall of the thorax. This device allows a more homogeneous distribution of ventilation, protecting the anterior areas from overdistension and favoring the redistribution of ventilation towards the posterior regions. Dramatic improvement in the airways mechanics has been reported in patients with ARDS.
