Ventilación diferencial en el manejo del síndrome de distress respiratorio agudo secundario a mediastinitis necrotizante descendente: rol de la tomografía axial computarizada dinámica de pulmón / Use of dinamic lung computed tomography to orient mechanical ventilation in adult respiratory distress syndrome: report of 1 case with acute mediastinitis

ABSTRACT

Lung computed tomography (CT) is being used increasingly to assess lung morphology in patients on mechanical ventilation. Lung CT under known levels of airway pressure (dynamic CT) can also assess the response of lung parenchyma to ventilatory therapy. We report a patient with acute respiratory distress syndrome secondary to descending necrotizing mediastinitis, in whom lung dynamic CT oriented ventilatory management. Independent lung ventilation improved gas exchange and helped patient recovery
