[Mechanical ventilation of acute lung injury].
Acute lung injury (ALI) is of paramount importance for modern intensive care since it is one of the most frequent conditions necessitating admission to an ICU. ALI is characterised by severe life threatening hypoxemia which is based on ventilation perfusion mismatching within the lung. This is mostly resulting from atelectasis formation due to primary or secondary inflammation of lung tissue. Many studies showed that this inflammatory process is not restricted to the respiratory system but might result in non pulmonary organ failure and hemodynamic compromise as well. Mechanical ventilation is considered the hallmark treatment for ALI patients aimed to recruit lung tissue and thereby reverse hypoxemia without causing additional lung injury potentially resulting from overdistention or cycling collapse during expiration. Scientific evidence shows us that prevention of ventilator induced lung injury by protective ventilation with reduced tidal volumes is resulting in better clinical outcomes. Moreover, different technologies and adjunctive therapies have been suggested based on their pathophysiology. All these treatment options will be summarized in this article. Given the clear evidence for protective ventilation and bearing in mind that clinical application of this easy concept is still not widespread we will focus on this aspect.
