Reversal of Acute Exacerbations of Chronic Obstructive Lung Disease by Inspiratory Assistance with a Face Mask

Abstract
Patients with acute exacerbations of chronic obstructive pulmonary disease may require endotracheal intubation with mechanical ventilation. We designed, and here report on the efficacy of, a noninvasive ventilatory-assistance apparatus to provide inspiratory-pressure support by means of a face mask.
