Protective ventilation strategy in the acute respiratory distress syndrome

Abstract

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) contribute to progressive hypoxemia in critically ill patients. It has been proved that conventional mechanical ventilation with physiological respiratory volume contributes to further lung damage. In this respect, application of protective ventilatory strategy--pulmonary ventilation with limited volume and pressure can avoid mentioned consequences. The aim of this paper is to discuss mechanims by which elements contained in protective mechanical ventilation of patients with ALI/ARDS prevent further progrssive lung injury, to argue the effects of positive end--expiratory pressure and present insturctions for its application.
