ARDS – Ein Update – Teil 2: Therapie und Outcome

Abstract

The Acute Respiratory Distress Syndrome (ARDS) is defined by hypoxemic respiratory failure due to inflammatory response within the lung usually requiring invasive mechanical ventilation. Despite more than 50 years of scientific research numerous issues especially regarding mechanical ventilation as the most important treatment option remain unclear. Most important, adjustment of mechanical ventilation is challenging due to desirable beneficial effects on pulmonary gas exchange on the one hand and deleterious effects in terms of ventilator-associated lung injury on the other. Specifically, optimal settings of positive end-expiratory pressure and the role of spontaneous breathing activity are still controversial. Because no specific pharmacological therapy revealed beneficial effects until today, adjunctive treatment is actually limited to prone positioning and restrictive fluid balance. Long-term outcome of ARDS survivors is often affected by anxiety and mental health disorders.
